- Nuklear - 2.00.0 - public domain
- no warranty implied; use at your own risk.
- authored from 2015-2017 by Micha Mettke
-
-ABOUT:
-    This is a minimal state graphical user interface single header toolkit
-    written in ANSI C and licensed under public domain.
-    It was designed as a simple embeddable user interface for application and does
-    not have any dependencies, a default renderbackend or OS window and input handling
-    but instead provides a very modular library approach by using simple input state
-    for input and draw commands describing primitive shapes as output.
-    So instead of providing a layered library that tries to abstract over a number
-    of platform and render backends it only focuses on the actual UI.
-
-VALUES:
-    - Graphical user interface toolkit
-    - Single header library
-    - Written in C89 (a.k.a. ANSI C or ISO C90)
-    - Small codebase (~18kLOC)
-    - Focus on portability, efficiency and simplicity
-    - No dependencies (not even the standard library if not wanted)
-    - Fully skinnable and customizable
-    - Low memory footprint with total memory control if needed or wanted
-    - UTF-8 support
-    - No global or hidden state
-    - Customizable library modules (you can compile and use only what you need)
-    - Optional font baker and vertex buffer output
-
-USAGE:
-    This library is self contained in one single header file and can be used either
-    in header only mode or in implementation mode. The header only mode is used
-    by default when included and allows including this header in other headers
-    and does not contain the actual implementation.
-
-    The implementation mode requires to define  the preprocessor macro
-    NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.:
-
-        #define NK_IMPLEMENTATION
-        #include "nuklear.h"
-
-    Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
-    below in header and implementation mode if you want to use additional functionality
-    or need more control over the library.
-    IMPORTANT:  Every time you include "nuklear.h" you have to define the same flags.
-                This is very important not doing it either leads to compiler errors
-                or even worse stack corruptions.
-
-FEATURES:
-    - Absolutely no platform dependent code
-    - Memory management control ranging from/to
-        - Ease of use by allocating everything from standard library
-        - Control every byte of memory inside the library
-    - Font handling control ranging from/to
-        - Use your own font implementation for everything
-        - Use this libraries internal font baking and handling API
-    - Drawing output control ranging from/to
-        - Simple shapes for more high level APIs which already have drawing capabilities
-        - Hardware accessible anti-aliased vertex buffer output
-    - Customizable colors and properties ranging from/to
-        - Simple changes to color by filling a simple color table
-        - Complete control with ability to use skinning to decorate widgets
-    - Bendable UI library with widget ranging from/to
-        - Basic widgets like buttons, checkboxes, slider, ...
-        - Advanced widget like abstract comboboxes, contextual menus,...
-    - Compile time configuration to only compile what you need
-        - Subset which can be used if you do not want to link or use the standard library
-    - Can be easily modified to only update on user input instead of frame updates
-
-OPTIONAL DEFINES:
-    NK_PRIVATE
-        If defined declares all functions as static, so they can only be accessed
-        inside the file that contains the implementation
-
-    NK_INCLUDE_FIXED_TYPES
-        If defined it will include header <stdint.h> for fixed sized types
-        otherwise nuklear tries to select the correct type. If that fails it will
-        throw a compiler error and you have to select the correct types yourself.
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_DEFAULT_ALLOCATOR
-        if defined it will include header <stdlib.h> and provide additional functions
-        to use this library without caring for memory allocation control and therefore
-        ease memory management.
-        <!> Adds the standard library with malloc and free so don't define if you
-            don't want to link to the standard library <!>
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_STANDARD_IO
-        if defined it will include header <stdio.h> and provide
-        additional functions depending on file loading.
-        <!> Adds the standard library with fopen, fclose,... so don't define this
-            if you don't want to link to the standard library <!>
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_STANDARD_VARARGS
-        if defined it will include header <stdarg.h> and provide
-        additional functions depending on variable arguments
-        <!> Adds the standard library with va_list and  so don't define this if
-            you don't want to link to the standard library<!>
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_VERTEX_BUFFER_OUTPUT
-        Defining this adds a vertex draw command list backend to this
-        library, which allows you to convert queue commands into vertex draw commands.
-        This is mainly if you need a hardware accessible format for OpenGL, DirectX,
-        Vulkan, Metal,...
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_FONT_BAKING
-        Defining this adds `stb_truetype` and `stb_rect_pack` implementation
-        to this library and provides font baking and rendering.
-        If you already have font handling or do not want to use this font handler
-        you don't have to define it.
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_DEFAULT_FONT
-        Defining this adds the default font: ProggyClean.ttf into this library
-        which can be loaded into a font atlas and allows using this library without
-        having a truetype font
-        <!> Enabling this adds ~12kb to global stack memory <!>
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INCLUDE_COMMAND_USERDATA
-        Defining this adds a userdata pointer into each command. Can be useful for
-        example if you want to provide custom shaders depending on the used widget.
-        Can be combined with the style structures.
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_BUTTON_TRIGGER_ON_RELEASE
-        Different platforms require button clicks occurring either on buttons being
-        pressed (up to down) or released (down to up).
-        By default this library will react on buttons being pressed, but if you
-        define this it will only trigger if a button is released.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_ZERO_COMMAND_MEMORY
-        Defining this will zero out memory for each drawing command added to a
-        drawing queue (inside nk_command_buffer_push). Zeroing command memory
-        is very useful for fast checking (using memcmp) if command buffers are
-        equal and avoid drawing frames when nothing on screen has changed since
-        previous frame.
-
-    NK_ASSERT
-        If you don't define this, nuklear will use <assert.h> with assert().
-        <!> Adds the standard library so define to nothing of not wanted <!>
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_BUFFER_DEFAULT_INITIAL_SIZE
-        Initial buffer size allocated by all buffers while using the default allocator
-        functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't
-        want to allocate the default 4k memory then redefine it.
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_MAX_NUMBER_BUFFER
-        Maximum buffer size for the conversion buffer between float and string
-        Under normal circumstances this should be more than sufficient.
-        <!> If used needs to be defined for implementation and header <!>
-
-    NK_INPUT_MAX
-        Defines the max number of bytes which can be added as text input in one frame.
-        Under normal circumstances this should be more than sufficient.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_MEMSET
-        You can define this to 'memset' or your own memset implementation
-        replacement. If not nuklear will use its own version.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_MEMCPY
-        You can define this to 'memcpy' or your own memcpy implementation
-        replacement. If not nuklear will use its own version.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_SQRT
-        You can define this to 'sqrt' or your own sqrt implementation
-        replacement. If not nuklear will use its own slow and not highly
-        accurate version.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_SIN
-        You can define this to 'sinf' or your own sine implementation
-        replacement. If not nuklear will use its own approximation implementation.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_COS
-        You can define this to 'cosf' or your own cosine implementation
-        replacement. If not nuklear will use its own approximation implementation.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_STRTOD
-        You can define this to `strtod` or your own string to double conversion
-        implementation replacement. If not defined nuklear will use its own
-        imprecise and possibly unsafe version (does not handle nan or infinity!).
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_DTOA
-        You can define this to `dtoa` or your own double to string conversion
-        implementation replacement. If not defined nuklear will use its own
-        imprecise and possibly unsafe version (does not handle nan or infinity!).
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_VSNPRINTF
-        If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO`
-        and want to be safe define this to `vsnprintf` on compilers supporting
-        later versions of C or C++. By default nuklear will check for your stdlib version
-        in C as well as compiler version in C++. if `vsnprintf` is available
-        it will define it to `vsnprintf` directly. If not defined and if you have
-        older versions of C or C++ it will be defined to `vsprintf` which is unsafe.
-        <!> If used it is only required to be defined for the implementation part <!>
-
-    NK_BYTE
-    NK_INT16
-    NK_UINT16
-    NK_INT32
-    NK_UINT32
-    NK_SIZE_TYPE
-    NK_POINTER_TYPE
-        If you compile without NK_USE_FIXED_TYPE then a number of standard types
-        will be selected and compile time validated. If they are incorrect you can
-        define the correct types by overloading these type defines.

- *  Usage
- *  -------------------
- *  To use a context it first has to be initialized which can be achieved by calling
- *  one of either `nk_init_default`, `nk_init_fixed`, `nk_init`, `nk_init_custom`.
- *  Each takes in a font handle and a specific way of handling memory. Memory control
- *  hereby ranges from standard library to just specifying a fixed sized block of memory
- *  which nuklear has to manage itself from.

- *                                  DRAWING
- *
- * =============================================================================*/
-/*  This library was designed to be render backend agnostic so it does
- *  not draw anything to screen directly. Instead all drawn shapes, widgets
- *  are made of, are buffered into memory and make up a command queue.
- *  Each frame therefore fills the command buffer with draw commands
- *  that then need to be executed by the user and his own render backend.
- *  After that the command buffer needs to be cleared and a new frame can be
- *  started. It is probably important to note that the command buffer is the main
- *  drawing API and the optional vertex buffer API only takes this format and
- *  converts it into a hardware accessible format.
- *
- *  Usage
- *  -------------------
- *  To draw all draw commands accumulated over a frame you need your own render
- *  backend able to draw a number of 2D primitives. This includes at least
- *  filled and stroked rectangles, circles, text, lines, triangles and scissors.
- *  As soon as this criterion is met you can iterate over each draw command
- *  and execute each draw command in a interpreter like fashion:
- *
- *      const struct nk_command *cmd = 0;
- *      nk_foreach(cmd, &ctx) {
- *      switch (cmd->type) {
- *      case NK_COMMAND_LINE:
- *          your_draw_line_function(...)
- *          break;
- *      case NK_COMMAND_RECT
- *          your_draw_rect_function(...)
- *          break;
- *      case ...:
- *          [...]
- *      }
- *
- *  In program flow context draw commands need to be executed after input has been
- *  gathered and the complete UI with windows and their contained widgets have
- *  been executed and before calling `nk_clear` which frees all previously
- *  allocated draw commands.
- *
- *      struct nk_context ctx;
- *      nk_init_xxx(&ctx, ...);
- *      while (1) {
- *          Event evt;
- *          nk_input_begin(&ctx);
- *          while (GetEvent(&evt)) {
- *              if (evt.type == MOUSE_MOVE)
- *                  nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
- *              else if (evt.type == [...]) {
- *                  [...]
- *              }
- *          }
- *          nk_input_end(&ctx);
- *
- *          [...]
- *
- *          const struct nk_command *cmd = 0;
- *          nk_foreach(cmd, &ctx) {
- *          switch (cmd->type) {
- *          case NK_COMMAND_LINE:
- *              your_draw_line_function(...)
- *              break;
- *          case NK_COMMAND_RECT
- *              your_draw_rect_function(...)
- *              break;
- *          case ...:
- *              [...]
- *          }
- *          nk_clear(&ctx);
- *      }
- *      nk_free(&ctx);
- *
- *  You probably noticed that you have to draw all of the UI each frame which is
- *  quite wasteful. While the actual UI updating loop is quite fast rendering
- *  without actually needing it is not. So there are multiple things you could do.
- *
- *  First is only update on input. This of course is only an option if your
- *  application only depends on the UI and does not require any outside calculations.
- *  If you actually only update on input make sure to update the UI two times each
- *  frame and call `nk_clear` directly after the first pass and only draw in
- *  the second pass. In addition it is recommended to also add additional timers
- *  to make sure the UI is not drawn more than a fixed number of frames per second.
- *
- *      struct nk_context ctx;
- *      nk_init_xxx(&ctx, ...);
- *      while (1) {
- *          [...wait for input ]
- *
- *          [...do two UI passes ...]
- *          do_ui(...)
- *          nk_clear(&ctx);
- *          do_ui(...)
- *
- *          const struct nk_command *cmd = 0;
- *          nk_foreach(cmd, &ctx) {
- *          switch (cmd->type) {
- *          case NK_COMMAND_LINE:
- *              your_draw_line_function(...)
- *              break;
- *          case NK_COMMAND_RECT
- *              your_draw_rect_function(...)
- *              break;
- *          case ...:
- *              [...]
- *          }
- *          nk_clear(&ctx);
- *      }
- *      nk_free(&ctx);
- *
- *  The second probably more applicable trick is to only draw if anything changed.
- *  It is not really useful for applications with continuous draw loop but
- *  quite useful for desktop applications. To actually get nuklear to only
- *  draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and
- *  allocate a memory buffer that will store each unique drawing output.
- *  After each frame you compare the draw command memory inside the library
- *  with your allocated buffer by memcmp. If memcmp detects differences
- *  you have to copy the command buffer into the allocated buffer
- *  and then draw like usual (this example uses fixed memory but you could
- *  use dynamically allocated memory).
- *
- *      [... other defines ...]
- *      #define NK_ZERO_COMMAND_MEMORY
- *      #include "nuklear.h"
- *
- *      struct nk_context ctx;
- *      void *last = calloc(1,64*1024);
- *      void *buf = calloc(1,64*1024);
- *      nk_init_fixed(&ctx, buf, 64*1024);
- *      while (1) {
- *          [...input...]
- *          [...ui...]
- *
- *          void *cmds = nk_buffer_memory(&ctx.memory);
- *          if (memcmp(cmds, last, ctx.memory.allocated)) {
- *              memcpy(last,cmds,ctx.memory.allocated);
- *              const struct nk_command *cmd = 0;
- *              nk_foreach(cmd, &ctx) {
- *                  switch (cmd->type) {
- *                  case NK_COMMAND_LINE:
- *                      your_draw_line_function(...)
- *                      break;
- *                  case NK_COMMAND_RECT
- *                      your_draw_rect_function(...)
- *                      break;
- *                  case ...:
- *                      [...]
- *                  }
- *              }
- *          }
- *          nk_clear(&ctx);
- *      }
- *      nk_free(&ctx);
- *
- *  Finally while using draw commands makes sense for higher abstracted platforms like
- *  X11 and Win32 or drawing libraries it is often desirable to use graphics
- *  hardware directly. Therefore it is possible to just define
- *  `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output.
- *  To access the vertex output you first have to convert all draw commands into
- *  vertexes by calling `nk_convert` which takes in your preferred vertex format.
- *  After successfully converting all draw commands just iterate over and execute all
- *  vertex draw commands:
- *
- *      struct nk_convert_config cfg = {};
- *      static const struct nk_draw_vertex_layout_element vertex_layout[] = {
- *          {NK_VERTEX_POSITION, NK_FORMAT_FLOAT, NK_OFFSETOF(struct your_vertex, pos)},
- *          {NK_VERTEX_TEXCOORD, NK_FORMAT_FLOAT, NK_OFFSETOF(struct your_vertex, uv)},
- *          {NK_VERTEX_COLOR, NK_FORMAT_R8G8B8A8, NK_OFFSETOF(struct your_vertex, col)},
- *          {NK_VERTEX_LAYOUT_END}
- *      };
- *      cfg.shape_AA = NK_ANTI_ALIASING_ON;
- *      cfg.line_AA = NK_ANTI_ALIASING_ON;
- *      cfg.vertex_layout = vertex_layout;
- *      cfg.vertex_size = sizeof(struct your_vertex);
- *      cfg.vertex_alignment = NK_ALIGNOF(struct your_vertex);
- *      cfg.circle_segment_count = 22;
- *      cfg.curve_segment_count = 22;
- *      cfg.arc_segment_count = 22;
- *      cfg.global_alpha = 1.0f;
- *      cfg.null = dev->null;
- *
- *      struct nk_buffer cmds, verts, idx;
- *      nk_buffer_init_default(&cmds);
- *      nk_buffer_init_default(&verts);
- *      nk_buffer_init_default(&idx);
- *      nk_convert(&ctx, &cmds, &verts, &idx, &cfg);

- *
- *                                  WINDOW
- *
- * =============================================================================
- * Windows are the main persistent state used inside nuklear and are life time
- * controlled by simply "retouching" (i.e. calling) each window each frame.
- * All widgets inside nuklear can only be added inside function pair `nk_begin_xxx`
- * and `nk_end`. Calling any widgets outside these two functions will result in an
- * assert in debug or no state change in release mode.
- *
- * Each window holds frame persistent state like position, size, flags, state tables,
- * and some garbage collected internal persistent widget state. Each window
- * is linked into a window stack list which determines the drawing and overlapping
- * order. The topmost window thereby is the currently active window.
- *
- * To change window position inside the stack occurs either automatically by
- * user input by being clicked on or programmatically by calling `nk_window_focus`.
- * Windows by default are visible unless explicitly being defined with flag
- * `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag
- * `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling
- * `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.
- *
- * Usage
- * -------------------
- * To create and keep a window you have to call one of the two `nk_begin_xxx`
- * functions to start window declarations and `nk_end` at the end. Furthermore it
- * is recommended to check the return value of `nk_begin_xxx` and only process
- * widgets inside the window if the value is not 0. Either way you have to call
- * `nk_end` at the end of window declarations. Furthermore, do not attempt to
- * nest `nk_begin_xxx` calls which will hopefully result in an assert or if not
- * in a segmentation fault.
- *
- *      if (nk_begin_xxx(...) {
- *          [... widgets ...]
- *      }
- *      nk_end(ctx);
- *
- * In the grand concept window and widget declarations need to occur after input
- * handling and before drawing to screen. Not doing so can result in higher
- * latency or at worst invalid behavior. Furthermore make sure that `nk_clear`
- * is called at the end of the frame. While nuklear's default platform backends
- * already call `nk_clear` for you if you write your own backend not calling
- * `nk_clear` can cause asserts or even worse undefined behavior.

- *                                  LAYOUT
- *
- * ============================================================================= */
-/*  Layouting in general describes placing widget inside a window with position and size.
- *  While in this particular implementation there are five different APIs for layouting
- *  each with different trade offs between control and ease of use.
- *
- *  All layouting methods in this library are based around the concept of a row.
- *  A row has a height the window content grows by and a number of columns and each
- *  layouting method specifies how each widget is placed inside the row.
- *  After a row has been allocated by calling a layouting functions and then
- *  filled with widgets will advance an internal pointer over the allocated row.
- *
- *  To actually define a layout you just call the appropriate layouting function
- *  and each subsequent widget call will place the widget as specified. Important
- *  here is that if you define more widgets then columns defined inside the layout
- *  functions it will allocate the next row without you having to make another layouting
- *  call.
- *
- *  Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API
- *  is that you have to define the row height for each. However the row height
- *  often depends on the height of the font.
- *
- *  To fix that internally nuklear uses a minimum row height that is set to the
- *  height plus padding of currently active font and overwrites the row height
- *  value if zero.
- *
- *  If you manually want to change the minimum row height then
- *  use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to
- *  reset it back to be derived from font height.
- *
- *  Also if you change the font in nuklear it will automatically change the minimum
- *  row height for you and. This means if you change the font but still want
- *  a minimum row height smaller than the font you have to repush your value.
- *
- *  For actually more advanced UI I would even recommend using the `nk_layout_space_xxx`
- *  layouting method in combination with a cassowary constraint solver (there are
- *  some versions on github with permissive license model) to take over all control over widget
- *  layouting yourself. However for quick and dirty layouting using all the other layouting
- *  functions should be fine.
- *
- *  Usage
- *  -------------------
- *  1.) nk_layout_row_dynamic
- *  The easiest layouting function is `nk_layout_row_dynamic`. It provides each
- *  widgets with same horizontal space inside the row and dynamically grows
- *  if the owning window grows in width. So the number of columns dictates
- *  the size of each widget dynamically by formula:
- *
- *      widget_width = (window_width - padding - spacing) * (1/colum_count)
- *
- *  Just like all other layouting APIs if you define more widget than columns this
- *  library will allocate a new row and keep all layouting parameters previously
- *  defined.
- *
- *      if (nk_begin_xxx(...) {
- *          // first row with height: 30 composed of two widgets
- *          nk_layout_row_dynamic(&ctx, 30, 2);
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // second row with same parameter as defined above
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // third row uses 0 for height which will use auto layouting
- *          nk_layout_row_dynamic(&ctx, 0, 2);
- *          nk_widget(...);
- *          nk_widget(...);
- *      }
- *      nk_end(...);
- *
- *  2.) nk_layout_row_static
- *  Another easy layouting function is `nk_layout_row_static`. It provides each
- *  widget with same horizontal pixel width inside the row and does not grow
- *  if the owning window scales smaller or bigger.
- *
- *      if (nk_begin_xxx(...) {
- *          // first row with height: 30 composed of two widgets with width: 80
- *          nk_layout_row_static(&ctx, 30, 80, 2);
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // second row with same parameter as defined above
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // third row uses 0 for height which will use auto layouting
- *          nk_layout_row_static(&ctx, 0, 80, 2);
- *          nk_widget(...);
- *          nk_widget(...);
- *      }
- *      nk_end(...);
- *
- *  3.) nk_layout_row_xxx
- *  A little bit more advanced layouting API are functions `nk_layout_row_begin`,
- *  `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly
- *  specify each column pixel or window ratio in a row. It supports either
- *  directly setting per column pixel width or widget window ratio but not
- *  both. Furthermore it is a immediate mode API so each value is directly
- *  pushed before calling a widget. Therefore the layout is not automatically
- *  repeating like the last two layouting functions.
- *
- *      if (nk_begin_xxx(...) {
- *          // first row with height: 25 composed of two widgets with width 60 and 40
- *          nk_layout_row_begin(ctx, NK_STATIC, 25, 2);
- *          nk_layout_row_push(ctx, 60);
- *          nk_widget(...);
- *          nk_layout_row_push(ctx, 40);
- *          nk_widget(...);
- *          nk_layout_row_end(ctx);
- *
- *          // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75
- *          nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2);
- *          nk_layout_row_push(ctx, 0.25f);
- *          nk_widget(...);
- *          nk_layout_row_push(ctx, 0.75f);
- *          nk_widget(...);
- *          nk_layout_row_end(ctx);
- *
- *          // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75
- *          nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2);
- *          nk_layout_row_push(ctx, 0.25f);
- *          nk_widget(...);
- *          nk_layout_row_push(ctx, 0.75f);
- *          nk_widget(...);
- *          nk_layout_row_end(ctx);
- *      }
- *      nk_end(...);
- *
- *  4.) nk_layout_row
- *  The array counterpart to API nk_layout_row_xxx is the single nk_layout_row
- *  functions. Instead of pushing either pixel or window ratio for every widget
- *  it allows to define it by array. The trade of for less control is that
- *  `nk_layout_row` is automatically repeating. Otherwise the behavior is the
- *  same.
- *
- *      if (nk_begin_xxx(...) {
- *          // two rows with height: 30 composed of two widgets with width 60 and 40
- *          const float size[] = {60,40};
- *          nk_layout_row(ctx, NK_STATIC, 30, 2, ratio);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75
- *          const float ratio[] = {0.25, 0.75};
- *          nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *
- *          // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75
- *          const float ratio[] = {0.25, 0.75};
- *          nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *      }
- *      nk_end(...);
- *
- *  5.) nk_layout_row_template_xxx
- *  The most complex and second most flexible API is a simplified flexbox version without
- *  line wrapping and weights for dynamic widgets. It is an immediate mode API but
- *  unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called
- *  before calling the templated widgets.
- *  The row template layout has three different per widget size specifier. The first
- *  one is the static widget size specifier with fixed widget pixel width. They do
- *  not grow if the row grows and will always stay the same. The second size
- *  specifier is nk_layout_row_template_push_variable which defines a
- *  minimum widget size but it also can grow if more space is available not taken
- *  by other widgets. Finally there are dynamic widgets which are completely flexible
- *  and unlike variable widgets can even shrink to zero if not enough space
- *  is provided.
- *
- *      if (nk_begin_xxx(...) {
- *          // two rows with height: 30 composed of three widgets
- *          nk_layout_row_template_begin(ctx, 30);
- *          nk_layout_row_template_push_dynamic(ctx);
- *          nk_layout_row_template_push_variable(ctx, 80);
- *          nk_layout_row_template_push_static(ctx, 80);
- *          nk_layout_row_template_end(ctx);
- *
- *          nk_widget(...); // dynamic widget can go to zero if not enough space
- *          nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space
- *          nk_widget(...); // static widget with fixed 80 pixel width
- *
- *          // second row same layout
- *          nk_widget(...);
- *          nk_widget(...);
- *          nk_widget(...);
- *      }
- *      nk_end(...);
- *
- *  6.) nk_layout_space_xxx
- *  Finally the most flexible API directly allows you to place widgets inside the
- *  window. The space layout API is an immediate mode API which does not support
- *  row auto repeat and directly sets position and size of a widget. Position
- *  and size hereby can be either specified as ratio of allocated space or
- *  allocated space local position and pixel size. Since this API is quite
- *  powerful there are a number of utility functions to get the available space
- *  and convert between local allocated space and screen space.
- *
- *      if (nk_begin_xxx(...) {
- *          // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
- *          nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX);
- *          nk_layout_space_push(ctx, nk_rect(0,0,150,200));
- *          nk_widget(...);
- *          nk_layout_space_push(ctx, nk_rect(200,200,100,200));
- *          nk_widget(...);
- *          nk_layout_space_end(ctx);
- *
- *          // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
- *          nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX);
- *          nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1));
- *          nk_widget(...);
- *          nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1));
- *          nk_widget(...);
- *      }
- *      nk_end(...);

- *                          FONT
- *
- * ===============================================================*/
-/*  Font handling in this library was designed to be quite customizable and lets
-    you decide what you want to use and what you want to provide. There are three
-    different ways to use the font atlas. The first two will use your font
-    handling scheme and only requires essential data to run nuklear. The next
-    slightly more advanced features is font handling with vertex buffer output.
-    Finally the most complex API wise is using nuklear's font baking API.
-
-    1.) Using your own implementation without vertex buffer output
-    --------------------------------------------------------------
-    So first up the easiest way to do font handling is by just providing a
-    `nk_user_font` struct which only requires the height in pixel of the used
-    font and a callback to calculate the width of a string. This way of handling
-    fonts is best fitted for using the normal draw shape command API where you
-    do all the text drawing yourself and the library does not require any kind
-    of deeper knowledge about which font handling mechanism you use.
-    IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist
-    over the complete life time! I know this sucks but it is currently the only
-    way to switch between fonts.
-
-        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
-        {
-            your_font_type *type = handle.ptr;
-            float text_width = ...;
-            return text_width;
-        }
-
-        struct nk_user_font font;
-        font.userdata.ptr = &your_font_class_or_struct;
-        font.height = your_font_height;
-        font.width = your_text_width_calculation;
-
-        struct nk_context ctx;
-        nk_init_default(&ctx, &font);
-
-    2.) Using your own implementation with vertex buffer output
-    --------------------------------------------------------------
-    While the first approach works fine if you don't want to use the optional
-    vertex buffer output it is not enough if you do. To get font handling working
-    for these cases you have to provide two additional parameters inside the
-    `nk_user_font`. First a texture atlas handle used to draw text as subimages
-    of a bigger font atlas texture and a callback to query a character's glyph
-    information (offset, size, ...). So it is still possible to provide your own
-    font and use the vertex buffer output.
-
-        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
-        {
-            your_font_type *type = handle.ptr;
-            float text_width = ...;
-            return text_width;
-        }
-        void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint)
-        {
-            your_font_type *type = handle.ptr;
-            glyph.width = ...;
-            glyph.height = ...;
-            glyph.xadvance = ...;
-            glyph.uv[0].x = ...;
-            glyph.uv[0].y = ...;
-            glyph.uv[1].x = ...;
-            glyph.uv[1].y = ...;
-            glyph.offset.x = ...;
-            glyph.offset.y = ...;
-        }
-
-        struct nk_user_font font;
-        font.userdata.ptr = &your_font_class_or_struct;
-        font.height = your_font_height;
-        font.width = your_text_width_calculation;
-        font.query = query_your_font_glyph;
-        font.texture.id = your_font_texture;
-
-        struct nk_context ctx;
-        nk_init_default(&ctx, &font);
-
-    3.) Nuklear font baker
-    ------------------------------------
-    The final approach if you do not have a font handling functionality or don't
-    want to use it in this library is by using the optional font baker.
-    The font baker APIs can be used to create a font plus font atlas texture
-    and can be used with or without the vertex buffer output.
-
-    It still uses the `nk_user_font` struct and the two different approaches
-    previously stated still work. The font baker is not located inside
-    `nk_context` like all other systems since it can be understood as more of
-    an extension to nuklear and does not really depend on any `nk_context` state.
-
-    Font baker need to be initialized first by one of the nk_font_atlas_init_xxx
-    functions. If you don't care about memory just call the default version
-    `nk_font_atlas_init_default` which will allocate all memory from the standard library.
-    If you want to control memory allocation but you don't care if the allocated
-    memory is temporary and therefore can be freed directly after the baking process
-    is over or permanent you can call `nk_font_atlas_init`.
-
-    After successfully initializing the font baker you can add Truetype(.ttf) fonts from
-    different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`.
-    functions. Adding font will permanently store each font, font config and ttf memory block(!)
-    inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
-    the font baker by for example adding additional fonts you can call
-    `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end).
-
-    As soon as you added all fonts you wanted you can now start the baking process
-    for every selected glyph to image by calling `nk_font_atlas_bake`.
-    The baking process returns image memory, width and height which can be used to
-    either create your own image object or upload it to any graphics library.
-    No matter which case you finally have to call `nk_font_atlas_end` which
-    will free all temporary memory including the font atlas image so make sure
-    you created our texture beforehand. `nk_font_atlas_end` requires a handle
-    to your font texture or object and optionally fills a `struct nk_draw_null_texture`
-    which can be used for the optional vertex output. If you don't want it just
-    set the argument to `NULL`.
-
-    At this point you are done and if you don't want to reuse the font atlas you
-    can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration
-    memory. Finally if you don't use the font atlas and any of it's fonts anymore
-    you need to call `nk_font_atlas_clear` to free all memory still being used.
-
-        struct nk_font_atlas atlas;
-        nk_font_atlas_init_default(&atlas);

-    how to merge fonts, configure a font with `nk_font_config` to use other languages,
-    use another texture coordinate format and a lot more:
-
-        struct nk_font_config cfg = nk_font_config(font_pixel_height);
-        cfg.merge_mode = nk_false or nk_true;
-        cfg.range = nk_font_korean_glyph_ranges();
-        cfg.coord_type = NK_COORD_PIXEL;
-        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

- *                          MEMORY BUFFER
- *
- * ===============================================================*/
-/*  A basic (double)-buffer with linear allocation and resetting as only
-    freeing policy. The buffer's main purpose is to control all memory management
-    inside the GUI toolkit and still leave memory control as much as possible in
-    the hand of the user while also making sure the library is easy to use if
-    not as much control is needed.
-    In general all memory inside this library can be provided from the user in
-    three different ways.
-
-    The first way and the one providing most control is by just passing a fixed
-    size memory block. In this case all control lies in the hand of the user
-    since he can exactly control where the memory comes from and how much memory
-    the library should consume. Of course using the fixed size API removes the
-    ability to automatically resize a buffer if not enough memory is provided so
-    you have to take over the resizing. While being a fixed sized buffer sounds
-    quite limiting, it is very effective in this library since the actual memory
-    consumption is quite stable and has a fixed upper bound for a lot of cases.
-
-    If you don't want to think about how much memory the library should allocate
-    at all time or have a very dynamic UI with unpredictable memory consumption
-    habits but still want control over memory allocation you can use the dynamic
-    allocator based API. The allocator consists of two callbacks for allocating
-    and freeing memory and optional userdata so you can plugin your own allocator.
-
-    The final and easiest way can be used by defining
-    NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory
-    allocation functions malloc and free and takes over complete control over
-    memory in this library.

- *
- * ===============================================================*/
-/* Editing text in this library is handled by either `nk_edit_string` or
- * `nk_edit_buffer`. But like almost everything in this library there are multiple
- * ways of doing it and a balance between control and ease of use with memory
- * as well as functionality controlled by flags.
- *
- * This library generally allows three different levels of memory control:
- * First of is the most basic way of just providing a simple char array with
- * string length. This method is probably the easiest way of handling simple
- * user text input. Main upside is complete control over memory while the biggest
- * downside in comparison with the other two approaches is missing undo/redo.
- *
- * For UIs that require undo/redo the second way was created. It is based on
- * a fixed size nk_text_edit struct, which has an internal undo/redo stack.
- * This is mainly useful if you want something more like a text editor but don't want
- * to have a dynamically growing buffer.
- *
- * The final way is using a dynamically growing nk_text_edit struct, which
- * has both a default version if you don't care where memory comes from and an
- * allocator version if you do. While the text editor is quite powerful for its
- * complexity I would not recommend editing gigabytes of data with it.
- * It is rather designed for uses cases which make sense for a GUI library not for
- * an full blown text editor.

- *                          DRAWING
- *
- * ===============================================================*/
-/*  This library was designed to be render backend agnostic so it does
-    not draw anything to screen. Instead all drawn shapes, widgets
-    are made of, are buffered into memory and make up a command queue.
-    Each frame therefore fills the command buffer with draw commands
-    that then need to be executed by the user and his own render backend.
-    After that the command buffer needs to be cleared and a new frame can be
-    started. It is probably important to note that the command buffer is the main
-    drawing API and the optional vertex buffer API only takes this format and
-    converts it into a hardware accessible format.
-
-    To use the command queue to draw your own widgets you can access the
-    command buffer of each window by calling `nk_window_get_canvas` after
-    previously having called `nk_begin`:
-
-        void draw_red_rectangle_widget(struct nk_context *ctx)
-        {
-            struct nk_command_buffer *canvas;
-            struct nk_input *input = &ctx->input;
-            canvas = nk_window_get_canvas(ctx);
-
-            struct nk_rect space;
-            enum nk_widget_layout_states state;
-            state = nk_widget(&space, ctx);
-            if (!state) return;
-
-            if (state != NK_WIDGET_ROM)
-                update_your_widget_by_user_input(...);
-            nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0));
-        }
-
-        if (nk_begin(...)) {
-            nk_layout_row_dynamic(ctx, 25, 1);
-            draw_red_rectangle_widget(ctx);
-        }
-        nk_end(..)
-
-    Important to know if you want to create your own widgets is the `nk_widget`
-    call. It allocates space on the panel reserved for this widget to be used,
-    but also returns the state of the widget space. If your widget is not seen and does
-    not have to be updated it is '0' and you can just return. If it only has
-    to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both
-    update and draw your widget. The reason for separating is to only draw and
-    update what is actually necessary which is crucial for performance.

-/*  Since nuklear is supposed to work on all systems providing floating point
-    math without any dependencies I also had to implement my own math functions
-    for sqrt, sin and cos. Since the actual highly accurate implementations for
-    the standard library functions are quite complex and I do not need high
-    precision for my use cases I use approximations.
-
-    Sqrt
-    ----
-    For square root nuklear uses the famous fast inverse square root:
-    https://en.wikipedia.org/wiki/Fast_inverse_square_root with
-    slightly tweaked magic constant. While on today's hardware it is
-    probably not faster it is still fast and accurate enough for
-    nuklear's use cases. IMPORTANT: this requires float format IEEE 754
-
-    Sine/Cosine
-    -----------
-    All constants inside both function are generated Remez's minimax
-    approximations for value range 0...2*PI. The reason why I decided to
-    approximate exactly that range is that nuklear only needs sine and
-    cosine to generate circles which only requires that exact range.
-    In addition I used Remez instead of Taylor for additional precision:
-    www.lolengine.net/blog/2011/12/21/better-function-approximations.
-
-    The tool I used to generate constants for both sine and cosine
-    (it can actually approximate a lot more functions) can be
-    found here: www.lolengine.net/wiki/oss/lolremez

+This repository contains the source code for the ARM side libraries used on Raspberry Pi.
+These typically are installed in /opt/vc/lib and includes source for the ARM side code to interface to:
+EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, WFC, OpenVG.
+
+Use buildme to build. It requires cmake to be installed and an arm cross compiler. It is set up to use this one:
+https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian
+
+Note that this repository does not contain the source for the edidparser and vcdbg binaries due to licensing restrictions.

+Building on Pi
+++++++++++++++
+
+To build the test apps on the pi, first build the libs:
+make -C libs/ilclient
+make -C libs/vgfont
+
+then by entering each test app directory and run make. E.g.
+  cd hello_world
+  make
+  ./hello_world.bin
+
+Running ./rebuild.sh will rebuild the all libs and and apps.
+
+
+Building on a different PC
+++++++++++++++++++++++++++
+
+If you want to build the samples on a different machine (cross-compile) then set:
+SDKSTAGE=<path/to/firmware-directory> and CC=<path/to/cross-compiler>
+before running make.

+
+/**
+ * \file 
+ *
+ * \brief This API allows the host to provide PCM samples to be
+ * rendered via <DFN>audio_render</DFN>.
+ * 
+ * This file describes a simple API for host applications to play sound
+ * using VideoCore.  It includes the functionality to:
+ * 
+ * \li open/close
+ * \li set pcm parameters
+ * \li set buffer size parameters
+ * \li retrieve empty buffer available to use
+ * \li send full buffer to be played
+ * \li retrieve current buffering level
+ * 
+ * This API has no thread context of it's own, so the caller must be
+ * aware that the IL API will be used in context.  This has
+ * implications on executing calls inside callback contexts, and on
+ * the minimum size of stack that the caller requires.  See the
+ * <DFN>ilclient_stack_size()</DFN> function for assistance.
+ * 
+ * This API will use a single <DFN>audio_render</DFN> IL component, and
+ * supply buffers to the input port using the OpenMAX IL base profile mode.

+between 256 and 4,194,304 points inclusive.  A transpose function, which also
+uses the 3D hardware, is provided to support 2-dimensional transforms.
+
+
+*** Accuracy ***
+
+GPU_FFT uses single-precision floats for data and twiddle factors.  The output
+is not scaled.  The relative root-mean-square (rms) error in parts-per-million
+(ppm) for different transform lengths (N) is typically:
+
+log2(N) |  8    |  9    | 10    | 11    | 12    | 13    | 14    | 15
+ppm rms |  0.33 |  0.46 |  0.52 |  0.59 |  0.78 |  0.83 |  0.92 |  0.98
+
+log2(N) | 16    | 17    | 18    | 19    | 20    |  21   | 22
+ppm rms |  1.0  |  1.3  |  1.3  |  1.4  |  1.5  |  1.5  |  1.5
+
+Accuracy has improved significantly over previous releases at the expense of a
+small (2%) performance hit; however, FFTW is still one order of magnitude more
+accurate than GPU_FFT.
+
+
+*** Throughput ***
+
+GPU_FFT 1.0 had to be invoked through a "mailbox" which added a 100us overhead
+on every call.  To mitigate this, batches of transforms could be submitted via
+a single call.  GPU_FFT now avoids this 100us overhead by poking GPU registers
+directly from the ARM if total batch runtime will be short; but still uses the
+mailbox for longer jobs to avoid busy waiting at 100% CPU for too long.
+
+Typical per-transform runtimes for batch sizes of 1 and 10; and comparative
+figures for FFTW (FFTW_MEASURE mode) on a Pi 1 with L2 cache enabled are:
+
+log2(N) |   8   |   9   |  10   |  11   |  12  |  13  |  14  |  15
+      1 | 0.033 | 0.049 | 0.070 | 0.12  | 0.25 | 0.61 |  1.2 |  3.5
+     10 | 0.017 | 0.029 | 0.049 | 0.11  | 0.27 | 0.66 |  1.2 |  3.3
+   FFTW | 0.092 | 0.22  | 0.48  | 0.95  | 3.0  | 5.1  | 12   | 31
+
+log2(N) |  16  |  17 |  18 |  19 |   20 |   21 |   22        All times in
+      1 |  7.0 |  17 |  43 |  97 |  194 |  388 |  786        milliseconds
+   FFTW | 83   | 180 | 560 | 670 | 1600 | 3400 | 8800        2 sig. figs.
+
+
+*** API functions ***
+
+    gpu_fft_prepare()       Call once to allocate memory and initialise data
+                            structures.  Returns 0 for success.
+
+    gpu_fft_execute()       Call one or more times to execute a previously
+                            prepared FFT batch.  Returns 0 for success.
+
+    gpu_fft_release()       Call once to release resources after use.
+                            GPU memory is permanently lost if not freed.
+
+
+*** Parameters ***
+
+    int mb          Mailbox file descriptor obtained by calling mbox_open()
+
+    int log2_N      log2(FFT length) = 8 to 22
+
+    int direction   FFT direction:  GPU_FFT_FWD for forward FFT
+                                    GPU_FFT_REV for inverse FFT
+
+    int jobs        Number of transforms in batch = 1 or more
+
+    GPU_FFT **      Output parameter from prepare: control structure.
+    GPU_FFT *       Input parameter to execute and release
+
+
+*** Data format ***
+
+Complex data arrays are stored as alternate real and imaginary parts:
+
+    struct GPU_FFT_COMPLEX {
+        float re, im;
+    };
+
+The GPU_FFT struct created by gpu_fft_prepare() contains pointers to the input
+and output arrays:
+
+    struct GPU_FFT {
+       struct GPU_FFT_COMPLEX *in, *out;
+
+When executing a batch of transforms, buffer pointers are obtained as follows:
+
+    struct GPU_FFT *fft = gpu_fft_prepare( ... , jobs);
+    for (int j=0; j<jobs; j++) {
+       struct GPU_FFT_COMPLEX *in  = fft->in  + j*fft->step;
+       struct GPU_FFT_COMPLEX *out = fft->out + j*fft->step;
+
+GPU_FFT.step is greater than FFT length because a guard space is left between
+buffers for caching and alignment reasons.
+
+GPU_FFT performs multiple passes between ping-pong buffers.  The final output
+lands in the same buffer as input after an even number of passes.  Transforms
+where log2_N=12...16 use an odd number of passes and the final result is left
+out-of-place.  The input data is never preserved.
+
+
+*** Example program ***
+
+The code that produced the above accuracy and performance figures is included
+as a demo with the latest Raspbian distro.  Build and run it as follows:
+
+cd /opt/vc/src/hello_pi/hello_fft
+make
+sudo ./hello_fft.bin 12
+
+It accepts three optional command-line arguments: <log2_N> <batch> <loops>
+
+The special character device is required for the ioctl mailbox through which
+the ARM communicates with the Videocore GPU.
+
+
+*** With Open GL on Pi 1 ***
+
+GPU_FFT and Open GL will run concurrently on Pi 1 if GPU_FFT is configured not
+to use VC4 L2 cache by zeroing a define in file gpu_fft_base.c as follows:
+
+#define GPU_FFT_USE_VC4_L2_CACHE 0 // Pi 1 only: cached=1; direct=0
+
+Overall performance will probably be higher if GPU_FFT and Open GL take turns
+at using the 3D hardware.  Since eglSwapBuffers() returns immediately without
+waiting for rendering, call glFlush() and glFinish() afterwards as follows:
+
+    for (;;) {
+        ....
+        eglSwapBuffers(....); // non-blocking call returns immediately
+        glFlush();
+        glFinish(); // wait until V3D hardware is idle
+        ....
+        gpu_fft_execute(....); // blocking call
+        ....
+    }
+
+
+*** 2-dimensional FFT ***
+
+Please study the hello_fft_2d demo source, which is built and executed thus:
+
+make hello_fft_2d.bin
+sudo ./hello_fft_2d.bin
+
+This generates a Windows BMP file: "hello_fft_2d.bmp"
+
+The demo uses a square 512x512 array; however, rectangular arrays are allowed.
+The following lines in gpu_fft_trans.c will do what is safe:
+
+    ptr.arm.uptr[6] = src->x < dst->y? src->x : dst->y;
+    ptr.arm.uptr[7] = src->y < dst->x? src->y : dst->x;
+
+One may transpose the output from the second FFT pass back into the first pass
+input buffer, by preparing and executing a second transposition; however, this
+is probably unnecessary.  It depends on how the final output will be accessed.

+Official RI for OpenVG 1.1
+Released: May 13, 2008
+
+
+Release Notes
+-------------
+
+This release is based on OpenVG 1.1 and EGL 1.3 specifications.
+This release is Windows-only, although the source code
+compiles at least on Mac OS X 10.5 and Cygwin. Project files are
+provided for MSVC 6.
+
+This archive contains sources for OpenVG RI, VGU and EGL. There's
+also a precompiled libOpenVG.dll that contains OpenVG and EGL implementations.

+Samples
+-------
+
+Tiger
+
+The release contains a sample application that renders an image of a
+tiger. Note that the sample doesn't start immediately, since it takes
+a few seconds to render the image. Resizing the window rerenders the
+image in the new resolution.
+
+
+Known Issues
+------------
+
+-EGL functionality is incomplete (some functions lack proper error checking, some
+ attribs may not be processed, etc.)
+-When opening samples.dsw, MSVC may complain about missing Perforce connection. Just
+ ignore that.
+
+
+Changes
+-------
+
+Nov 25, 2008
+-Clamp color transform scale to [-127, 127] and bias to [-1, 1]
+
+May 13, 2008
+- Changed 8 sample MSAA configs into 32 sample configs
+- Changed max gaussian std deviation to 16 (was 128)
+- VG_DRAW_IMAGE_MULTIPLY converts luminance to RGB if either paint or image color is RGB
+- Fixes A40102 by storing input floats as is
+
+February 12, 2008
+- fixed arc transformation.
+- fixed point along path corner cases.
+- partially fixed A40102 by not filtering invalid float input.
+
+December 12, 2007
+- fixed an overflow bug in vgFillMaskLayer error handling.
+- increased accuracy for Gaussian blur. The new code avoids an infinite loop with a very small std dev.
+- fixed a bug in Font::find that caused deleted fonts to be returned.
+
+November 20, 2007
+- reimplemented 1,2 & 4 bits per pixel images
+- fixed vgGetParameter for paint
+- fixed https://cvs.khronos.org/bugzilla/show_bug.cgi?id=1095 RI handling of child images with shared storage
+  -vgGetParent: return closest valid ancestor, or image itself if no ancestor was found.
+- EGL refactoring & clean up
+- divided OS native parts of EGL into separate files that should be included in that platform's build
+- added a generic OS backend for EGL (not thread safe, no window rendering)
+- fixed https://cvs.khronos.org/bugzilla/show_bug.cgi?id=1943 RI does not handle channel mask correctly for lL/sL/BW1
+- removed EGL_IMAGE_IN_USE_ERROR from vgDrawGlyph(s)
+- added configs without an alpha mask to facilitate CTS reference image creation
+- implemented more accurate stroking by rendering each stroke part into a coverage buffer and compositing from there
+  -fixes https://cvs.khronos.org/bugzilla/show_bug.cgi?id=2221 RI errors at end of curved strokes.
+- bugfix: joins used path midpoints, interpolateStroke and caps didn't => seams (visible in some G60101 cases)
+- vgCreateMaskLayer returns VG_INVALID_HANDLE if the current surface doesn't have a mask layer
+- vgRenderToMask bugfix: temp buffer is now cleared between fill and stroke
+- bugfix: vgCreateImage returns an error if allowedQuality is zero
+- bugfix: vgSetPaint returns an error if paintModes is zero
+- bugfix: vgCreateFont doesn't return an error if capacityHint is zero
+- bugfix: writeFilteredPixel writes also into luminance formats
+
+October 12, 2007
+-Upgrade to OpenVG 1.1, including
+  -Implemented MSAA, added 4 and 8 sample EGLConfigs
+  -Implemented VG_A_4 and VG_A_1 image formats and EGLConfigs
+  -Implemented Glyph API
+  -Implemented new masking functions
+  -Implemented color transform
+-Implemented native EGL backends for Windows & Mac OS X => Fix for bugzilla 1376 RI uses non-standard EGL implementation
+  *RI now works with CTS generation's native_w32.c (native_ri.c can be removed).
+  *dependency on GLUT has been removed. GLUT code is still included and can be compiled in instead of native by defining RI_USE_GLUT.
+-16 bit EGLConfigs now expose 4 mask bits, 8 bit configs 8, 4 bit configs 4, and 1 bit configs 1. MSAA configs expose one bit per sample.
+-EGL now works with any display, not just EGL_DEFAULT_DISPLAY
+-Simplification: removed code to handle less than 8 bits per pixel. Smaller bit depths always allocate 8 bits per pixel.
+-Changed rasterizer data types to RScalar and RVector2 so that it's possible to alter RIfloat precision without affecting rasterization.
+-Accuracy: increased circularLerp precision
+-Bugfix: matrix inversion now checks if the input matrix is affine and forces the inverted matrix to be affine as well
+-Bugfix: fixed eglCopyBuffers (copied from dst to dst)
+-Bugfix: fixed eglCreatePixmapSurface (allowed only VG_sRGBA_8888, didn't give an error if config had more than one sample per pixel)
+-Bugfix: bugzilla 2465: RI asserts when setting maximum amount of gradient stops
+
+February 27, 2007
+-changed to MIT open source license.
+-bugfix, bugzilla 820: RGB and luminance are now treated as different color spaces.
+-bugfix, bugzilla 1094/1095: vgGetParent now returns the input image in case its parent is already destroyed.
+
+December 1, 2006
+-bugfix, bugzilla 649: allowed image quality is now taken into account when deciding resampling filter.
+-bugfix, bugzilla 650, bad stroking accuracy reported by TK Chan and Mika Tuomi: curve tessellation is now increased from 64 to 256. RI_MAX_EDGES has been increased from 100000 to 262144 to facilitate the increased number of edges.
+-bugfix, reported by Chris Wynn, affects I30206: degenerate gradients in repeat mode now render the first stop color instead of the last one.
+-changed float to RIfloat, added an option to compile RIfloat into a class to test reduced precision float ops
+
+September 6, 2006
+-bugfix, bugzilla 591: CLOSE_PATH followed by a MOVE_TO doesn't produce an extra end cap anymore
+-abs values of arc axis lengths are taken only just before rendering
+-undefined bits of bitfields are now ignored in the API
+
+September 1, 2006
+-changed colorToInt to use mathematical round-to-nearest as recommended by new language in section 3.4.4.
+-implemented VG_PAINT_COLOR_RAMP_PREMULTIPLIED
+-implemented VG_STROKE_DASH_PHASE_RESET
+-implemented new language for filter channelMasks (section 11.2)
+-tangents returned by vgPointAlongPath are now normalized
+-implemented VG_MAX_GAUSSIAN_STD_DEVIATION, rewrote Gaussian blur code
+-vgGetString: if no context, return NULL. VG_VERSION returns the spec version (1.0).
+-bugfix, bugzilla 542: vgSeparableConvolve now convolves the edge color with the horizontal kernel and uses that as the edge color for the vertical pass
+-ellipse rh and rv are replaced by their absolute values whenever read for processing, the absolute values are not written into the path data
+
+August 18, 2006
+-bugfix, M30301: the arguments for vguComputeWarpQuadToQuad were the wrong way around, destination should come before source.
+-bugfix, M10102: check for degeneracy in vguComputeWarpSquareToQuad is done before the affinity check so that degenerate affine matrices also produce the bad warp error
+-bugfix, bugzilla 491: Chris Wynn's vgComputeWarpSquareToQuad -case. There was a wrong mapping between vertices, (1,1) was mapped to (dx2,dy2)
+-bugfix, bugzilla 519: vguPolygon wrong error check. vguPolygon didn't have an error check for the count argument
+-bugfix, bugzilla 518: vgGetParameterfv/iv wrong errors. vgGetParametrtfv/iv error checking was for count < 0 instead of count <= 0.
+-bugfix, bugzilla 517: wrong cap flag checked in vgPathTransformedBounds
+-bugfix, bugzilla 494: egl.h has wrong values for OPENVG_BIT and OPENGL_ES_BIT. Copied the enumerations from the 1.3 egl.h on the Khronos site (OpenKode/egl/egl.h)
+-bugfix, bugzilla 492: gradient filter window was biased
+-bugfix: when appending paths, there was a loop over coordinates to replace arc axis lengths by their absolute values. However, if the path wasn't empty, the loop accessed wrong coordinates. Fixes: Qingping Zhang's cases 2&3.
+-bugfix: image filter write mask was ignored when writing to VG_A_8 images. Fixes: Qingping Zhang's case 13.
+-bugfix: if image filter processing format is premultiplied, color channels are clamped to alpha before conversion to destination format
+-bugfix: in eglReleaseThread the EGL instance was freed when its reference count reached zero, but the pointer wasn't made NULL, causing the use of uninitialized instance.
+-bugfix: vgClearImage didn't clamp the clear color to [0,1] range
+-bugfix: a zero-length dash at a path vertex produces a join
+-bugfix: vgSetParameter now checks paramType for all object types
+-bugfix: convolution filters incorrectly restricted the area read from the source image to the intersection of source and destination image sizes
+-bugfix: EGL surface creation now defaults correctly to EGL_COLOR_SPACE_sRGB
+-antialiasing is done in the linear color space as the spec recommends.
+-image filters clamp the result to [0,1] range.
+-Color::pack and Color::convert assert that their input is in [0,1] range
+-in case a projective transform is used, VGImageMode is always VG_DRAW_IMAGE_NORMAL
+-the default value for VG_FILTER_FORMAT_LINEAR is now VG_FALSE
+-added Matrix::isAffine for easy affinity check
+-Color::clamp clamps color channels to alpha for premultiplied colors
+-VG_BLEND_LIGHTEN: color channels cannot exceed alpha anymore
+-RI now supports flexible pixel formats. Any bit depth for RGBA is now supported.
+-eglGetProcAddress is now properly implemented, it returns a function pointer for eglSetConfigPreferenceHG extension
+-eglQueryString now returns "eglSetConfigPreferenceHG" for EGL_EXTENSIONS
+-location of egl.h in RI. use EGL/egl.h, VG/openvg.h, VG/vgu.h
+-OpenVG 1.0.1 spec changes
+ +use the latest openvg.h
+ +2.8: AA happens in linear space
+ +3.4: alpha channel depth of zero results in alpha=1 when read
+ +4.1: return VG_NO_CONTEXT_ERROR from vgGetError in case no context is current
+ +5.1: VG_SCREEN_LAYOUT (default = screen layout of the display)
+ +5.2, 5.3: vgSet, vgGet, vgSetParameter, vgGetParameter: handling of invalid values of count
+ +5.2.1: new default for VG_FILTER_FORMAT_LINEAR is VG_FALSE
+ +8.5.3: get rid of VG_PATH_DATATYPE_INVALID and VG_IMAGE_FORMAT_INVALID enums
+ +10.2: get rid of old extension image formats, add the official ones
+ +10.5: when reading/writing pixels, clamp color channels to [0, alpha]
+ +10.8: when a projective transform is used, always use VG_DRAW_IMAGE_NORMAL mode
+ +10.8: VG_DRAW_IMAGE_MULTIPLY: if color spaces of paint and image don't match, no conversion takes place, result is in image color space
+ +12.4: clamp the result of additive blend to [0,1]
+
+October 20, 2005
+-Gradients are filtered to avoid aliasing
+-Subpaths that ended with a close path segment were capped and joined incorrectly. Fixed.

+ * \brief This API defines helper functions for writing IL clients.
+ *
+ * This file defines an IL client side library.  This is useful when
+ * writing IL clients, since there tends to be much repeated and
+ * common code across both single and multiple clients.  This library
+ * seeks to remove that common code and abstract some of the
+ * interactions with components.  There is a wrapper around a
+ * component and tunnel, and some operations can be done on lists of
+ * these.  The callbacks from components are handled, and specific
+ * events can be checked or waited for.

+ *
+ * This file defines an IL client side library.  This is useful when
+ * writing IL clients, since there tends to be much repeated and
+ * common code across both single and multiple clients.  This library
+ * seeks to remove that common code and abstract some of the
+ * interactions with components.  There is a wrapper around a
+ * component and tunnel, and some operations can be done on lists of
+ * these.  The callbacks from components are handled, and specific
+ * events can be checked or waited for.

+// Font handling for graphicsx
+
+/** @file font.c
+  *
+  * Fairly primitive font handling, just enough to emulate the old API.
+  *
+  * Hinting and Font Size
+  *
+  * The old API does not create fonts explicitly, it just renders them
+  * as needed. That works fine for unhinted fonts, but for hinted fonts we
+  * care about font size.
+  *
+  * Since we now *can* do hinted fonts, we should do. Regenerating the
+  * fonts each time becomes quite slow, so we maintain a cache of fonts.
+  *
+  * For the typical applications which use graphics_x this is fine, but
+  * won't work well if lots of fonts sizes are used.
+  *
+  * Unicode
+  *
+  * This API doesn't support unicode at all at present, nor UTF-8.

+# RaspiCam Documentation
+
+This document describes the use of the four Raspberry Pi camera applications as of February 19th 2018.
+
+There are four applications provided, **raspistill**, **raspivid**, **raspiyuv** and **raspividyuv**. raspistill and raspiyuv are very similar and are intended for capturing images, raspivid and raspividyuv are for capturing video.
+
+All the applications are command line driven, written to take advantage of the mmal API which runs over OpenMAX. The mmal API provides an easier to use system than that presented by OpenMAX. Note that mmal is a Broadcom specific API used only on Videocore 4 systems.
+
+The applications use up to four OpenMAX(mmal) components - camera, preview,  encoder and null_sink. All applications use the camera component, raspistill uses the Image Encode component, raspivid uses the Video Encode component and raspiyuv and raspividyuv do not use an encoder, and sends their YUV or RGB output direct from camera component to file.
+
+The preview display is optional, but can be used full screen or directed to a specific rectangular area on the display. If preview is disabled, the null_sink component is used to 'absorb' the preview frames. It is necessary for the camera to produce preview frames even if not required for display, as they are used for calculating exposure and white balance settings.
+
+In addition it is possible to omit the filename option, in which case the preview is displayed but no file is written, or to redirect all output to stdout.
+     
+Command line help is available by typing just the application name in on the command line.
+
+
+## Setting up the Camera hardware
+
+
+**Warning.** Cameras are static sensitive. Earth yourself prior to handling the PCB, a sink tap/faucet or similar should suffice if you don't have an earthing strap.
+The camera board attaches to the Raspberry Pi via a 15 way ribbon cable. There are only two connections to make, the ribbon cable need to be attached to the camera PCB and the Raspberry Pi itself. You need to get it the right way round or the camera will not work. On the camera PCB, the blue backing on the cable should be away from the PCB, and on the Raspberry Pi it should be towards the Ethernet connection (or where the Ethernet connector would be if you are using a model A).
+
+Although the connectors on the PCB and the Pi are different, they work in a similar way. On the Raspberry Pi, pull up the tabs on each end of the connector. It should slide up easily, and be able to pivot around slightly. Fully insert the ribbon cable into the slot, ensuring it is straight, then gently press down the tabs to clip it into place. The camera PCB itself also requires you to pull the tabs away from the board, gently insert the cable, then push the tabs back. The PCB connector is a little more awkward than the one on the Pi itself. 
+
+## Setting up the Camera software
+
+Execute the following instructions on the command line to download and install the latest kernel,  GPU firmware and applications. You will need a internet connection for this to work correctly.
+
+	sudo apt-get update
+	sudo apt-get upgrade
+
+Now you need to enable camera support using the raspi-config program you will have used when you first set up your Raspberry Pi.
+
+	sudo raspi-config
+
+Use the cursor keys to move to the camera option and select enable. On exiting raspi-config it will ask to reboot. The enable option will ensure that on reboot the correct GPU firmware will be running (with the camera driver and tuning), and the GPU memory split is sufficient to allow the camera to acquire enough memory to run correctly. 
+
+To test that the system is installed and working, try the following command : 
+
+	raspistill -v -o test.jpg
+
+The display should show a 5 second preview from the camera and then take a picture, saved to the file test.jpg, whilst display various informational messages.
+
+## Troubleshooting
+
+If the camera is not working correctly, there are number of things to try. 
+Are the ribbon connectors all firmly seated and the right way round? They must be straight in their sockets.
+Is the camera module connector firmly attached to the camera PCB? This is the connection from the smaller black camera module itself to the camera PCB. Sometimes this connection can come loose. Using a fingernail, flip up the connector on the PCB, then reseat it with gentle pressure, it engages with a very slight click.
+Have sudo apt-get update, sudo apt-get upgrade been run?
+Has raspi-config been run and the camera enabled?
+Is your power supply sufficient? The camera adds about 200-250mA to the power requirements of the Raspberry Pi.
+
+So, if things are still not working, try the following:
+
+Error : raspistill/raspivid not found. This probably means your update/upgrade failed in some way. Try it again.
+
+Error : ENOMEM displayed. Camera is not starting up. Check all connections again. 
+
+Error : ENOSPC displayed. Camera is probably running out of GPU memory. Check config.txt in the /boot/ folder. The gpu_mem option should be at least 128.
+
+If after all the above, the camera is still not working, it may be defective. Try posting on the Raspberry Pi forum (Camera section) to see if there is any more help available there.
+
+## Common Command line Options
+Preview Window
+
+
+	--preview,	-p   	Preview window settings <'x,y,w,h'>

+
+## Application specific settings
+
+### raspistill
+
+--width,		-w		Set image width <size>
+--height,	-h		Set image height <size>
+--quality,  	-q		Set jpeg quality <0 to 100>
+
+Quality 100 is almost completely uncompressed. 75 is a good all round value
+
+	--raw,		-r		Add raw bayer data to jpeg metadata
+
+This option inserts the raw Bayer data from the camera in to the JPEG metadata
+
+	--output	-o		Output filename <filename>.
+
+Specify the output filename. If not specified, no file is saved. If the filename is '-', then all output is sent to stdout.
+
+	--latest		-l		Link latest frame to filename <filename>
+
+Make a file system link under this name to the latest frame.
+
+	--verbose,	-v		Output verbose information during run
+
+Outputs debugging/information messages during the program run.
+
+	--timeout,	-t		Time before takes picture and shuts down.
+
+The program will run for this length of time, then take the capture (if output is specified). If not specified, this is set to 5 seconds. 
+
+	--timelapse,	-tl		Timelapse mode.
+
+The specific value is the time between shots in milliseconds. Note you should specify %04d at the point in the filename where you want a frame count number to appear. e.g.
+
+		-t 30000 -tl 2000 -o image%04d.jpg
+
+You can also name the files with timestamp (-ts) or datetime(-dt)
+
+		-t 30000 -tl 2000 -ts -o image%d.jpg
+		-t 30000 -tl 2000 -dt -o image2015%10d.jpg
+
+will produce a capture every 2 seconds, over a total period of 30s, named image1.jpg, image0002.jpg..image0015.jpg. Note that the %04d indicates a 4 digit number with leading zero's added to pad to the required number of digits. So, for example,  %08d would result in an 8 digit number.
+
+If a timelapse value of 0 is entered, the application will take pictures as fast as possible. Note there is an minimum enforced pause of 30ms between captures to ensure that exposure calculations can be made. 
+
+	--thumb,	-th		Set thumbnail parameters (x:y:quality)
+
+Allows specification of the thumbnail image inserted in to the JPEG file. If not specified, defaults are a size of 64x48 at quality 35.
+
+	--demo, 	-d	 	Run a demo mode <milliseconds>
+
+This options cycles through range of camera options, no capture is done, the demo will end at the end of the timeout period, irrespective of whether all the options have been cycled. The time between cycles should be specified as a millisecond value.
+
+	--encoding,	-e		Encoding to use for output file
+
+Valid options are jpg, bmp, gif and png. Note that unaccelerated image types (gif, png, bmp) will take much longer to save than JPG which is hardware accelerated. Also note that the filename suffix is completely ignored when deciding the encoding of a file.
+
+	--exif,		-x		EXIF tag to apply to captures (format as 'key=value')
+
+Allows the insertion of specific exif tags in to the JPEG image. You can have up to 32 exif tge entries. This is useful for things like adding GPS metadata. For example, to set the Longitude
+
+		--exif GPS.GPSLongitude=5/1,10/1,15/100
+
+would set the Longitude to 5degs, 10 minutes, 15 seconds. See exif documentation for more details on the range of tags available; the supported tags are as follows.

+InteroperabilityIndex, InteroperabilityVersion, RelatedImageFileFormat, RelatedImageWidth, RelatedImageLength>
+
+Note that a small subset of these tags will be set automatically by the camera system, but will be overridden by any exif options on the command line.
+
+	--fullpreview,		-fp	Full Preview mode
+
+This runs the preview windows using the full resolution capture mode. Maximum frames per second in this mode is 15fps and the preview will have the same field of view as the capture. Captures should happen more quickly as no mode change should be required. This feature is currently under development.
+
+	--keypress		-k	Keypress mode
+
+The camera is run for the requested time (-t), and a captures can be initiated throughout that by pressing the Enter key.  Press X then Enter will exit the application before the timeout is reached. If the timeout is set to 0, the camera will run indefinitely until X then Enter is typed.
+Additional supported keys: 'i', 'o' and 'r'. Press 'i' then Enter will zoom in by 10%. Press 'o' then Enter will zoom out by 10%.  Press 'r' then Enter will reset zoom.
+Using the verbose option (-v) will display a prompt asking for user input, otherwise no prompt is displayed.
+
+	--signal			-s	Signal mode
+
+The camera is run for the requested time (-t), and a captures can be initiated throughout that time by sending a USR1 signal to the camera process. If USR2 signal is received the application makes a capture and exits. This can be done using the kill command. You can find the camera process ID using the 'ps ax' command or using pidof command.
+
+		kill -USR1 <process id of raspistill>
+		kill -USR2 <process id of raspistill>
+
+### raspistillyuv
+
+
+Many of the options for raspistillyuv are the same as those for raspistill. This section shows the differences.
+
+Unsupported Options:
+	--exif, --encoding, --thumb, --raw, --quality
+
+Extra Options :
+
+	--rgb,		-rgb	Save uncompressed data as RGB888
+
+This option forces the image to be saved as RGB data with 8 bits per channel, rather than YUV420. 
+
+Note that the image buffers saved in raspistillyuv are padded to a horizontal size divisible by 16 (so there may be unused bytes at the end of each line to made the width divisible by 16). Buffers are also padded vertically to be divisible by 16, and in the YUV mode, each plane of Y,U,V is padded in this way.
+
+
+### raspivid
+
+
+	--width,		-w	Set image width <size>
+
+Width of resulting video. This should be between 64 and 1920.
+
+	--height,	-h	Set image height <size>
+
+Height of resulting video. This should be between 64 and 1080.
+
+	--bitrate,	-b	Set bitrate. 
+
+Use bits per second, so 10MBits/s would be -b 10000000. For H264, 1080p a high quality bitrate would be 15Mbits/s or more.
+
+	--output	-o	Output filename <filename>.
+
+Specify the output filename. If not specified, no file is saved. If the filename is '-', then all output is sent to stdout.
+
+	--verbose,	-v	Output verbose information during run
+
+Outputs debugging/information messages during the program run.
+
+	--timeout,	-t	Time before takes picture and shuts down.
+
+The program will run for this length of time, then take the capture (if output is specified). If not specified, this is set to 5seconds. Setting 0 will mean the application will run continuously until stopped with Ctrl-C.
+
+	--demo, 	-d	Run a demo mode <milliseconds>
+
+This options cycles through range of camera options, no capture is done, the demo will end at the end of the timeout period, irrespective of whether all the options have been cycled. The time between cycles should be specified as a millisecond value.
+
+	--framerate, 	-fps  	Specify the frames per second to record
+
+At present, the minimum frame rate allowed is 2fps, the maximum is 30fps. This is likely to change in the future.
+
+	--penc,		-e	Display preview image *after* encoding
+
+Switch on an option to display the preview after compression. This will show any compression artefacts in the preview window. In normal operation, the preview will show the camera output prior to being compressed. This option is not guaranteed to work in future releases.
+
+	--intra,    	-g  	Specify the intra refresh period (key frame rate/GoP)
+
+Sets the intra refresh period (GoP) rate for the recorded video. H264 video uses a complete frame (I-frame) every intra refresh period from which subsequent frames are based. This options specifies the numbers of frames between each I-frame. Larger numbers here will reduce the size of the resulting video, smaller numbers make the stream more robust to error. Setting 0 will produce an initial I-frame and then just P-frames.
+
+	--profile,	-pf	Specify H264 profile to use for encoding
+
+Sets the H264 profile to be used for the encoding. Options are :  baseline, main, high.
+
+Examples
+
+Still captures
+
+By default, captures are done at the highest resolution supported by the sensor.  This can be changed using the -w and -h command line options.
+
+Taking a default capture after 2s (note times are specified in milliseconds) on viewfinder, saving in image.jpg
+
+	raspistill -t 2000 -o image.jpg
+
+Take a capture at a different resolution.
+
+	raspistill -t 2000 -o image.jpg -w 640 -h 480
+
+Now reduce the quality considerably to reduce file size
+
+	raspistill -t 2000 -o image.jpg -q 5
+
+Force the preview to appear at coordinate 100,100, with width 300 and height 200 pixels.
+
+	raspistill -t 2000 -o image.jpg -p 100,100,300,200
+
+Disable preview entirely
+
+	raspistill -t 2000 -o image.jpg -n
+
+Save the image as a png file (lossless compression, but slower than JPEG). Note that the filename suffix is ignored when choosing the image encoding. 
+
+	raspistill -t 2000 -o image.png -e png 
+
+Add some EXIF information to the JPEG. This sets the Artist tag name to Boris, and the GPS altitude to 123.5m. Note that if setting GPS tags you should set as a minimum GPSLatitude, GPSLatitudeRef, GPSLongitude, GPSLongitudeRef, GPSAltitude and GPSAltitudeRef.
+
+	raspistill -t 2000 -o image.jpg -x IFDO.Artist=Boris -x GPS.GPSAltitude=1235/10
+
+Set an emboss style image effect
+
+	raspistill -t 2000 -o image.jpg -ifx emboss
+
+Set the U and V channels of the YUV image to specific values (128:128 produces a greyscale image)
+
+	raspistill -t 2000 -o image.jpg -cfx 128:128
+
+Run preview ONLY for 2s, no saved image.
+
+	raspistill -t 2000 
+
+Take timelapse picture, one every 10 seconds for 10 minutes (10 minutes = 600000ms), named image_num_001_today.jpg, image_num_002_today.jpg onwards, with the latest picture also available under the name latest.jpg.
+
+	raspistill -t 600000 -tl 10000 -o image_num_%03d_today.jpg -l latest.jpg
+
+Take a picture and send image data to stdout
+
+	raspistill -t 2000 -o - 
+
+Take a picture and send image data to file
+
+	raspistill -t 2000 -o - > my_file.jpg
+
+Run camera forever, taking a picture when Enter is pressed
+
+	raspistill -t 0 -k -o my_pics%02d.jpg 
+Video Captures
+
+Image size and preview settings are the same as for stills capture. Default size for video recording is 1080p (1920x1080)
+
+Record a 5s clip with default settings (1080p30)
+
+	raspivid -t 5000 -o video.h264
+
+Record a 5s clip at a specified bitrate (3.5MBits/s)
+
+	raspivid -t 5000 -o video.h264 -b 3500000
+
+Record a 5s clip at a specified framerate (5fps)
+
+	raspivid -t 5000 -o video.h264 -f 5
+
+Encode a 5s camera stream and send image data to stdout
+
+	raspivid -t 5000 -o - 
+

+ * Description
+ *
+ * 2 components are created; camera and preview.
+ * Camera component has three ports, preview, video and stills.
+ * Preview is connected using standard mmal connections, the stills output
+ * is written straight to the file in YUV 420 format via the requisite buffer
+ * callback. video port is not used
+ *
+ * We use the RaspiCamControl code to handle the specific camera settings.
+ * We use the RaspiPreview code to handle the generic preview

+/**
+ * \file RaspiTex.c
+ *
+ * A simple framework for extending a MMAL application to render buffers via
+ * OpenGL.
+ *
+ * MMAL buffers are often in YUV colour space and in either a planar or
+ * tile format which is not supported directly by V3D. Instead of copying
+ * the buffer from the GPU and doing a colour space / pixel format conversion
+ * the GL_OES_EGL_image_external is used. This allows an EGL image to be
+ * created from GPU buffer handle (MMAL opaque buffer handle). The EGL image
+ * may then be used to create a texture (glEGLImageTargetTexture2DOES) and
+ * drawn by either OpenGL ES 1.0 or 2.0 contexts.
+ *
+ * Notes:
+ * 1) GL_OES_EGL_image_external textures always return pixels in RGBA format.
+ *    This is also the case when used from a fragment shader.
+ *
+ * 2) The driver implementation creates a new RGB_565 buffer and does the color
+ *    space conversion from YUV. This happens in GPU memory using the vector
+ *    processor.
+ *
+ * 3) Each EGL external image in use will consume GPU memory for the RGB 565
+ *    buffer. In addition, the GL pipeline might require more than one EGL image
+ *    to be retained in GPU memory until the drawing commands are flushed.
+ *
+ *    Typically 128 MB of GPU memory is sufficient for 720p viewfinder and 720p
+ *    GL surface. If both the viewfinder and the GL surface are 1080p then
+ *    256MB of GPU memory is recommended, otherwise, for non-trivial scenes
+ *    the system can run out of GPU memory whilst the camera is running.
+ *
+ * 4) It is important to make sure that the MMAL opaque buffer is not returned
+ *    to MMAL before the GL driver has completed the asynchronous call to
+ *    glEGLImageTargetTexture2DOES. Deferring destruction of the EGL image and
+ *    the buffer return to MMAL until after eglSwapBuffers is the recommended.
+ *
+ * See also: http://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image_external.txt

+/**
+ * \file RaspiVid.c
+ * Command line program to capture a camera video stream and encode it to file.
+ * Also optionally display a preview/viewfinder of current camera input.
+ *
+ * Description
+ *
+ * 3 components are created; camera, preview and video encoder.
+ * Camera component has three ports, preview, video and stills.
+ * This program connects preview and video to the preview and video
+ * encoder. Using mmal we don't need to worry about buffers between these
+ * components, but we do need to handle buffers from the encoder, which
+ * are simply written straight to the file in the requisite buffer callback.
+ *
+ * If raw option is selected, a video splitter component is connected between
+ * camera and preview. This allows us to set up callback for raw camera data
+ * (in YUV420 or RGB format) which might be useful for further image processing.
+ *
+ * We use the RaspiCamControl code to handle the specific camera settings.
+ * We use the RaspiPreview code to handle the (generic) preview window

+ * \file RaspiVidYUV.c
+ * Command line program to capture a camera video stream and save file
+ * as uncompressed YUV420 data
+ * Also optionally display a preview/viewfinder of current camera input.
+ *
+ * Description
+ *
+  * 2 components are created; camera and preview.
+ * Camera component has three ports, preview, video and stills.
+ * Preview is connected using standard mmal connections, the video output
+ * is written straight to the file in YUV 420 format via the requisite buffer
+ * callback. Still port is not used
+ *
+ * We use the RaspiCamControl code to handle the specific camera settings.
+ * We use the RaspiPreview code to handle the generic preview

+ *       gps_open() becomes reentrant, what gps_open_r() used to be.
+ *       gps_poll() removed in favor of gps_read().  The raw hook is gone.
+ *       (Aug 2011, release 3.0)
+ * 5.1 - GPS_PATH_MAX uses system PATH_MAX; split24 flag added. New
+ *       model and serial members in part B of AIS type 24, conforming
+ *       with ITU-R 1371-4. New timedrift structure (Nov 2013, release 3.10).
+ * 6.0 - AIS type 6 and 8 get 'structured' flag; GPS_PATH_MAX
+ *       shortened because devices has moved out of the tail union. Sentence
+ *       tag fields dropped from emitted JSON. The shape of the skyview
+ *       structure has changed to make working with the satellites-used
+ *       bits less confusing. (January 2015, release 3.12).

+Post-processing example programs to play with the imv buffer:
+=============================================================
+
+Compile:
+--------
+gcc imv2pgm.c -o imv2pgm -lm
+
+gcc imv2txt.c -o imv2txt
+
+Record and split buffer:
+------------------------
+raspivid -x test.imv -o test.h264
+
+We need to split the buffer first using split:
+
+split -a 4 -d -b $(((120+1)\*68\*4)) test.imv frame-
+
+Play:
+-----
+Now we can transform the velocity magnitues to a pgm image
+
+./imv2pgm frame-0001 120 68 frame-0001.pgm
+
+Or loop over all frames and create a movie
+
+for i in frame-????; do ./imv2pgm $i 120 68 $i.pgm;convert $i.pgm $i.png; rm $i.pgm; done
+
+avconv -i frame-%04d.png motion.avi
+
+And we can create a text file for easy plotting
+
+./imv2txt frame-0001 120 68 frame-0001.dat
+
+This textfile has in each line the center position x y of the macro block and
+the velocities u and v and the sum of differences sad.
+
+These can be plot with xmgrace
+
+xmgrace -autoscale none -settype xyvmap frame-0001.dat -param plot.par

+/* VideoCore Shared Memory - user interface library.
+**
+** This library provides all the necessary abstraction for any application to
+** make use of the shared memory service which is distributed across a kernel
+** driver and a videocore service.
+**
+** It is an application design decision to choose or not to use this service.
+**
+** The logical flow of operations that a user application needs to follow when
+** using this service is:
+**
+**       1) Initialize the service.
+**       2) Allocate shared memory blocks.
+**       3) Start using the allocated blocks.
+**          - In order to gain ownership on a block, lock the allocated block,
+**            locking a block returns a valid address that the user application
+**            can access.
+**          - When finished with using the block for the current execution cycle
+**            or function, and so when giving up the ownership, unlock the block.
+**       4) A block can be locked/unlocked as many times required - within or outside
+**          of - a specific execution context.
+**       5) To completely release an allocated block, free it.
+**       6) If the service is no longer required, terminate it.
+**
+**
+** Some generic considerations:
+
+** Allocating memory blocks.
+**
+**   Memory blocks can be allocated in different manners depending on the cache
+**   behavior desired.  A given block can either be:
+
+**       - Allocated in a non cached fashion all the way through host and videocore.
+**       - Allocated in a cached fashion on host OR videocore.
+**       - Allocated in a cached fashion on host AND videocore.
+**
+**   It is an application decision to determine how to allocate a block.  Evidently
+**   if the application will be doing substantial read/write accesses to a given block,
+**   it is recommended to allocate the block at least in a 'host cached' fashion for
+**   better results.
+**
+**
+** Locking memory blocks.
+**
+**   When the memory block has been allocated in a host cached fashion, locking the
+**   memory block (and so taking ownership of it) will trigger a cache invalidation.
+**
+**   For the above reason and when using host cached allocation, it is important that
+**   an application properly implements the lock/unlock mechanism to ensure cache will
+**   stay coherent, otherwise there is no guarantee it will at all be.
+**
+**   It is possible to dynamically change the host cache behavior (ie cached or non
+**   cached) of a given allocation without needing to free and re-allocate the block.
+**   This feature can be useful for such application which requires access to the block
+**   only at certain times and not otherwise.  By changing the cache behavior dynamically
+**   the application can optimize performances for a given duration of use.
+**   Such dynamic cache behavior remapping only applies to host cache and not videocore
+**   cache.  If one requires to change the videocore cache behavior, then a new block
+**   must be created to replace the old one.
+**
+**   On successful locking, a valid pointer is returned that the application can use
+**   to access to data inside the block.  There is no guarantee that the pointer will
+**   stay valid following the unlock action corresponding to this lock.
+**
+**
+** Unocking memory blocks.
+**
+**   When the memory block has been allocated in a host cached fashion, unlocking the
+**   memory block (and so forgiving its ownership) will trigger a cache flush unless
+**   explicitely asked not to flush the cache for performances reasons.
+**
+**   For the above reason and when using host cached allocation, it is important that
+**   an application properly implements the lock/unlock mechanism to ensure cache will
+**   stay coherent, otherwise there is no guarantee it will at all be.
+**
+**
+** A complete API is defined below.

+   RPC_CALL[n]_OUT_CTRL(fn, id, RPC_THING(p0), RPC_THING(p1), ..., out)
+
+   Implementation notes:
+
+   In direct mode, fn is called directly and id is ignored.
+   Otherwise fn is ignored and an RPC message is constructed based on id.
+   The dispatch code is responsible for calculating the length of the returned data.
+
+   Preconditions:
+
+   p0, p1, ..., out satisfy the precondition to fn
+   id matches fn
+   Server is up (except for a special initialise call)
+
+   Postconditions:
+
+   The call to fn on the server has completed
+   We return whatever fn returned in out

+You could implement hashbig2() if you wanted but I haven't bothered here.
+
+If you want to find a hash of, say, exactly 7 integers, do

+4-byte integers to hash, use khrn_hashword().  If you have a byte array (like
+a character string), use khrn_hashlittle().  If you have several byte arrays, or
+a mix of things, see the comments above khrn_hashlittle().  
+
+Why is this so big?  I read 12 bytes at a time into 3 4-byte integers,

+   Global preconditions?
+
+   Server is up (needed by RPC_CALL[n]_RES)
+
+
+   Spec ambiguity:
+
+   What should we do if eglGetError is called twice? Currently we reset the error to EGL_SUCCESS.
+
+   eglGetConfigs:
+   "The number of configurations is returned in num config"
+   We assume this refers to the number of configurations returned, rather than the total number of
+   configurations available. (These are different values if config_size is too small).
+
+   eglChooseConfig:
+   Fail if the same attribute is specified more than once?
+   (I can't find anything in the spec saying what to do in this case)
+
+   In general, which attribute values are accepted and which raise
+   EGL_BAD_ATTRIBUTE is vague.
+
+   In particular, what do we do about the "ignored" and conditionally
+   ignored ones?
+
+   Currently ignoring ("ignored"):
+   case EGL_MAX_PBUFFER_HEIGHT:
+   case EGL_MAX_PBUFFER_PIXELS:
+   case EGL_MAX_PBUFFER_WIDTH:
+   case EGL_NATIVE_VISUAL_ID:
+
+   Currently not ignoring ("conditionally ignored")
+   case EGL_TRANSPARENT_BLUE_VALUE:
+   case EGL_TRANSPARENT_GREEN_VALUE:
+   case EGL_TRANSPARENT_RED_VALUE:
+
+   Currently ignoring ("conditionally ignored")
+   case EGL_NATIVE_VISUAL_TYPE:
+
+   The following sentences in the spec seem to contradict each other:
+   "If EGL_MATCH_NATIVE_PIXMAP is specified in attrib list, it must be followed
+by an attribute value"
+
+   "If EGL_DONT_CARE is specified as an attribute value, then the
+   attribute will not be checked. EGL_DONT_CARE may be specified for all attributes
+   except EGL_LEVEL."
+
+   In addition, EGL_NONE is listed as the default match value for EGL_MATCH_NATIVE_PIXMAP.
+   What happens if EGL_DONT_CARE or EGL_NONE is a valid native pixmap value?
+
+   What we actually do is we always treat the value supplied with EGL_MATCH_NATIVE_PIXMAP
+   as a valid handle (and fail if it's invalid), and ignore it only if it's not in the list
+   at all.
+
+
+   EGL_MATCH_NATIVE_PIXMAP: todo: we'll set thread->error to something like EGL_BAD_ATTRIBUTE; should we be setting it to EGL_BAD_NATIVE_PIXMAP?
+   What is EGL_PRESERVED_RESOURCES?
+
+
+
+   Do we need to do anything for EGL_LEVEL?
+
+   What is EGL_PRESERVED_RESOURCES?
+   What exactly are EGL_NATIVE_VISUAL_ID, EGL_NATIVE_VISUAL_TYPE?
+
+
+   Implementation notes:
+
+   We only support one display. This is assumed to have a native display_id
+   of 0 (==EGL_DEFAULT_DISPLAY) and an EGLDisplay id of 1
+
+   All EGL client functions preserve the invariant (CLIENT_THREAD_STATE_ERROR)
+
+   It would be nice for the EGL version to only be defined in one place (rather than both eglInitialize and eglQueryString).
+
+   We allow implicit casts from bool to EGLint
+
+
+   We make the following assumptions:
+
+      EGL_CONFIG_CAVEAT (all EGL_NONE)
+      EGL_COLOR_BUFFER_TYPE (all EGL_RGB_BUFFER)
+      EGL_SAMPLES (if EGL_SAMPLES is 1 then all 4 else all 0)
+      EGL_NATIVE_RENDERABLE is true
+      EGL_MAX_PBUFFER_WIDTH, EGL_MAX_PBUFFER_HEIGHT, EGL_MIN_SWAP_INTERVAL, EGL_MAX_SWAP_INTERVAL are the same for all configs
+
+      All configs support all of:
+         (EGL_PBUFFER_BIT | EGL_PIXMAP_BIT | EGL_WINDOW_BIT | EGL_VG_COLORSPACE_LINEAR_BIT | EGL_VG_ALPHA_FORMAT_PRE_BIT | EGL_MULTISAMPLE_RESOLVE_BOX_BIT | EGL_SWAP_BEHAVIOR_PRESERVED_BIT);
+
+
+   EGL_OPTIMAL_FORMAT_BIT_KHR: Considered optimal if no format conversion needs doing
+
+   EGL_TRANSPARENT_TYPE is always EGL_NONE because we don't support EGL_TRANSPARENT_RGB. Should there be an EGL_TRANSPARENT_ALPHA?

+Also affects global image (and possibly others?)
+   EGLAPI EGLBoolean EGLAPIENTRY eglInitialize(EGLDisplay dpy, EGLint *major, EGLint *minor)
+
+   Khronos documentation:
+
+   EGL may be initialized on a display by calling
+   EGLBoolean eglInitialize(EGLDisplay dpy, EGLint
+   *major, EGLint *minor);
+   EGL TRUE is returned on success, and major and minor are updated with the major
+   and minor version numbers of the EGL implementation (for example, in an EGL
+   1.2 implementation, the values of *major and *minor would be 1 and 2, respectively).
+   major and minor are not updated if they are specified as NULL.
+   EGL FALSE is returned on failure and major and minor are not updated. An
+   EGL BAD DISPLAY error is generated if the dpy argument does not refer to a valid
+   EGLDisplay. An EGL NOT INITIALIZED error is generated if EGL cannot be
+   initialized for an otherwise valid dpy.

+
+   Khronos documentation:
+
+   3.5.1 Creating On-Screen Rendering Surfaces
+   To create an on-screen rendering surface, first create a native platform window
+   with attributes corresponding to the desired EGLConfig (e.g. with the same color
+   depth, with other constraints specific to the platform). Using the platform-specific
+   type EGLNativeWindowType, which is the type of a handle to that native window,
+   then call:
+
+   EGLSurface eglCreateWindowSurface(EGLDisplay dpy, EGLConfig config, EGLNativeWindowType win,
+   const EGLint *attrib_list);
+
+   eglCreateWindowSurface creates an onscreen EGLSurface and returns a handle
+   to it. Any EGL context created with a compatible EGLConfig can be used to
+   render into this surface.
+
+   attrib list specifies a list of attributes for the window. The list has the same
+   structure as described for eglChooseConfig. Attributes that can be specified in
+   attrib list include EGL_RENDER_BUFFER, EGL_VG_COLORSPACE, and EGL_VG_ALPHA_FORMAT.
+   It is possible that some platforms will define additional attributes specific to
+   those environments, as an EGL extension.
+
+   attrib list may be NULL or empty (first attribute is EGL_NONE), in which case
+   all attributes assumes their default value as described below.
+   EGL_RENDER_BUFFER specifies which buffer should be used for client API
+   rendering to the window, as described in section 2.2.2. If its value is EGL_SINGLE_BUFFER,
+   then client APIs should render directly into the visible window.
+
+   If its value is EGL_BACK_BUFFER, then all client APIs should render into the back
+   buffer. The default value of EGL_RENDER_BUFFER is EGL_BACK_BUFFER.
+
+   Client APIs may not be able to respect the requested rendering buffer. To
+   determine the actual buffer being rendered to by a context, call eglQueryContext
+   (see section 3.7.4).
+
+   EGL_VG_COLORSPACE specifies the color space used by OpenVG when
+   rendering to the surface. If its value is EGL_VG_COLORSPACE_sRGB, then
+   a non-linear, perceptually uniform color space is assumed, with a corresponding
+   VGImageFormat of form VG_s*. If its value is EGL_VG_-
+   COLORSPACE_LINEAR, then a linear color space is assumed, with a corresponding
+   VGImageFormat of form VG_l*. The default value of EGL_VG_COLORSPACE
+   is EGL_VG_COLORSPACE_sRGB.
+
+   EGL_VG_ALPHA_FORMAT specifies how alpha values are interpreted by
+   OpenVG when rendering to the surface. If its value is EGL_VG_ALPHA_FORMAT_-
+   NONPRE, then alpha values are not premultipled. If its value is EGL_VG_ALPHA_-
+   FORMAT_PRE, then alpha values are premultiplied. The default value of EGL_VG_-
+   ALPHA_FORMAT is EGL_VG_ALPHA_FORMAT_NONPRE.
+
+   Note that the EGL_VG_COLORSPACE and EGL_VG_ALPHA_FORMAT attributes
+   are used only by OpenVG . EGL itself, and other client APIs such as OpenGL and
+   OpenGL ES , do not distinguish multiple colorspace models. Refer to section 11.2
+   of the OpenVG 1.0 specification for more information.
+
+   Similarly, the EGL_VG_ALPHA_FORMAT attribute does not necessarily control
+   or affect the window system’s interpretation of alpha values, even when the window
+   system makes use of alpha to composite surfaces at display time. The window system's
+   use and interpretation of alpha values is outside the scope of EGL. However,
+   the preferred behavior is for window systems to ignore the value of EGL_VG_-
+   ALPHA_FORMAT when compositing window surfaces.
+
+   On failure eglCreateWindowSurface returns EGL_NO_SURFACE. If the attributes
+   of win do not correspond to config, then an EGL_BAD_MATCH error is generated.
+   If config does not support rendering to windows (the EGL_SURFACE_TYPE
+   attribute does not contain EGL_WINDOW_BIT), an EGL_BAD_MATCH error is generated.
+   If config does not support the colorspace or alpha format attributes specified
+   in attrib list (as defined for eglCreateWindowSurface), an EGL_BAD_MATCH error
+   is generated. If config is not a valid EGLConfig, an EGL_BAD_CONFIG error
+   is generated. If win is not a valid native window handle, then an EGL_BAD_NATIVE_WINDOW
+   error should be generated. If there is already an EGLConfig
+   associated with win (as a result of a previous eglCreateWindowSurface call), then
+   an EGL_BAD_ALLOC error is generated. Finally, if the implementation cannot allocate
+   resources for the new EGL window, an EGL_BAD_ALLOC error is generated.

+
+   3.5.2 Creating Off-Screen Rendering Surfaces
+   EGL supports off-screen rendering surfaces in pbuffers. Pbuffers differ from windows
+   in the following ways:
+
+   1. Pbuffers are typically allocated in offscreen (non-visible) graphics memory
+   and are intended only for accelerated offscreen rendering. Allocation can fail
+   if there are insufficient graphics resources (implementations are not required
+   to virtualize framebuffer memory). Clients should deallocate pbuffers when
+   they are no longer in use, since graphics memory is often a scarce resource.
+
+   2. Pbuffers are EGL resources and have no associated native window or native
+   window type. It may not be possible to render to pbuffers using native
+   rendering APIs.
+
+   To create a pbuffer, call
+
+      EGLSurface eglCreatePbufferSurface(EGLDisplay dpy,
+         EGLConfig config, const EGLint
+         *attrib_list);
+
+   This creates a single pbuffer surface and returns a handle to it.
+   attrib list specifies a list of attributes for the pbuffer. The list has the same
+   structure as described for eglChooseConfig. Attributes that can be specified in
+   attrib list include EGL_WIDTH, EGL_HEIGHT, EGL_LARGEST_PBUFFER, EGL_TEXTURE_FORMAT,
+   EGL_TEXTURE_TARGET, EGL_MIPMAP_TEXTURE, EGL_VG_COLORSPACE, and EGL_VG_ALPHA_FORMAT.
+
+   It is possible that some platforms will define additional attributes specific to
+   those environments, as an EGL extension.
+
+   attrib list may be NULL or empty (first attribute is EGL_NONE), in which case
+   all the attributes assume their default values as described below.
+
+   EGL_WIDTH and EGL_HEIGHT specify the pixel width and height of the rectangular
+   pbuffer. If the value of EGLConfig attribute EGL_TEXTURE_FORMAT is
+   not EGL_NO_TEXTURE, then the pbuffer width and height specify the size of the
+   level zero texture image. The default values for EGL_WIDTH and EGL_HEIGHT are
+   zero.
+
+   EGL_TEXTURE_FORMAT specifies the format of the OpenGL ES texture that
+   will be created when a pbuffer is bound to a texture map. It can be set to EGL_-
+   TEXTURE_RGB, EGL_TEXTURE_RGBA, or EGL_NO_TEXTURE. The default value of
+   EGL_TEXTURE_FORMAT is EGL_NO_TEXTURE.
+
+   EGL_TEXTURE_TARGET specifies the target for the OpenGL ES texture that
+   will be created when the pbuffer is created with a texture format of EGL_-
+   TEXTURE_RGB or EGL_TEXTURE_RGBA. The target can be set to EGL_NO_-
+   TEXTURE or EGL_TEXTURE_2D. The default value of EGL_TEXTURE_TARGET is
+   EGL_NO_TEXTURE.
+
+   EGL_MIPMAP_TEXTURE indicates whether storage for OpenGL ES mipmaps
+   should be allocated. Space for mipmaps will be set aside if the attribute value
+   is EGL_TRUE and EGL_TEXTURE_FORMAT is not EGL_NO_TEXTURE. The default
+   value for EGL_MIPMAP_TEXTURE is EGL_FALSE.
+
+   Use EGL_LARGEST_PBUFFER to get the largest available pbuffer when the allocation
+   of the pbuffer would otherwise fail. The width and height of the allocated
+   pbuffer will never exceed the values of EGL_WIDTH and EGL_HEIGHT, respectively.
+   If the pbuffer will be used as a OpenGL ES texture (i.e., the value of
+   EGL_TEXTURE_TARGET is EGL_TEXTURE_2D, and the value of EGL_TEXTURE_-
+   FORMAT is EGL_TEXTURE_RGB or EGL_TEXTURE_RGBA), then the aspect ratio
+   will be preserved and the new width and height will be valid sizes for the texture
+   target (e.g. if the underlying OpenGL ES implementation does not support
+   non-power-of-two textures, both the width and height will be a power of 2). Use
+   eglQuerySurface to retrieve the dimensions of the allocated pbuffer. The default
+   value of EGL_LARGEST_PBUFFER is EGL_FALSE.
+
+   EGL_VG_COLORSPACE and EGL_VG_ALPHA_FORMAT have the same meaning
+   and default values as when used with eglCreateWindowSurface.
+   The resulting pbuffer will contain color buffers and ancillary buffers as specified
+   by config.
+
+   The contents of the depth and stencil buffers may not be preserved when rendering
+   an OpenGL ES texture to the pbuffer and switching which image of the
+   texture is rendered to (e.g., switching from rendering one mipmap level to rendering
+   another).
+
+   On failure eglCreatePbufferSurface returns EGL_NO_SURFACE. If the pbuffer
+   could not be created due to insufficient resources, then an EGL_BAD_ALLOC error
+   is generated. If config is not a valid EGLConfig, an EGL_BAD_CONFIG error is
+   generated. If the value specified for either EGL_WIDTH or EGL_HEIGHT is less
+   than zero, an EGL_BAD_PARAMETER error is generated. If config does not support
+   pbuffers, an EGL_BAD_MATCH error is generated. In addition, an EGL_BAD_MATCH
+   error is generated if any of the following conditions are true:
+
+   The EGL_TEXTURE_FORMAT attribute is not EGL_NO_TEXTURE, and EGL_WIDTH
+   and/or EGL_HEIGHT specify an invalid size (e.g., the texture size is
+   not a power of two, and the underlying OpenGL ES implementation does not
+   support non-power-of-two textures).
+
+   The EGL_TEXTURE_FORMAT attribute is EGL_NO_TEXTURE, and EGL_TEXTURE_TARGET
+   is something other than EGL_NO_TEXTURE; or, EGL_TEXTURE_FORMAT is something
+   other than EGL_NO_TEXTURE, and EGL_TEXTURE_TARGET is EGL_NO_TEXTURE.
+
+   Finally, an EGL_BAD_ATTRIBUTE error is generated if any of the EGL_TEXTURE_FORMAT,
+   EGL_TEXTURE_TARGET, or EGL_MIPMAP_TEXTURE attributes
+   are specified, but config does not support OpenGL ES rendering (e.g.
+   the EGL_RENDERABLE_TYPE attribute does not include at least one of EGL_OPENGL_ES_BIT
+   or EGL_OPENGL_ES2_BIT.

+   attrib_list is NULL or a pointer to an EGL_NONE-terminated list of attribute/value pairs
+
+   Postconditions:
+
+   The following conditions cause error to assume the specified value
+
+      EGL_BAD_DISPLAY               An EGLDisplay argument does not name a valid EGLDisplay
+      EGL_NOT_INITIALIZED           EGL is not initialized for the specified display.
+      EGL_BAD_CONFIG                config is not a valid EGLConfig
+      EGL_BAD_ATTRIBUTE             attrib_list contains an undefined EGL attribute or an attribute value that is unrecognized or out of range.
+           (TODO: EGL_BAD_ATTRIBUTE not mentioned in spec)
+      EGL_BAD_MATCH                 config doesn't support EGL_BIND_TO_TEXTURE_RGB(A) and you specify EGL_TEXTURE_FORMAT=EGL_TEXTURE_RGB(A)
+           (TODO: no mention of this in the spec)
+      EGL_BAD_ALLOC                 requested dimensions are larger than EGL_CONFIG_MAX_WIDTH x EGL_CONFIG_MAX_HEIGHT
+           (TODO: no mention of this in the spec)
+      EGL_BAD_ALLOC                 implementation cannot allocate resources for the new EGL window
+           (TODO: If there is already an EGLConfig associated with win)
+      EGL_SUCCESS                   Function succeeded.
+
+   if more than one condition holds, the first error is generated.
+
+   Return value is EGL_NO_SURFACE or an EGLSurface handle which is valid until the EGL session ends or
+   eglDestroySurface is called.

+
+   Khrnonos documentation:
+
+   Sorting of EGLConfigs
+   If more than one matching EGLConfig is found, then a list of EGLConfigs
+   is returned. The list is sorted by proceeding in ascending order of the ”Sort Priority”
+   column of table 3.4. That is, configurations that are not ordered by a lower
+   numbered rule are sorted by the next higher numbered rule.
+   Sorting for each rule is either numerically Smaller or Larger as described in the
+   ”Sort Order” column, or a Special sort order as described for each sort rule below:
+   1. Special: by EGL CONFIG CAVEAT where the precedence is EGL NONE,
+   EGL SLOW CONFIG, EGL NON CONFORMANT CONFIG.
+   2. Special:
+   by EGL COLOR BUFFER TYPE where the precedence is EGL RGB BUFFER,
+   EGL LUMINANCE BUFFER.
+   3. Special: by larger total number of color bits (for an RGB color buffer,
+   this is the sum of EGL RED SIZE, EGL GREEN SIZE, EGL BLUE SIZE,
+   and EGL ALPHA SIZE; for a luminance color buffer, the sum of
+   EGL LUMINANCE SIZE and EGL ALPHA SIZE) [3]. If the requested number
+   of bits in attrib list for a particular color component is 0 or EGL_DONT_CARE,
+   then the number of bits for that component is not considered.
+   4. Smaller EGL BUFFER SIZE.
+   5. Smaller EGL SAMPLE BUFFERS.
+   6. Smaller EGL SAMPLES.
+   7. Smaller EGL DEPTH SIZE.
+   8. Smaller EGL STENCIL SIZE.
+   9. Smaller EGL ALPHA MASK SIZE.
+   10. Special: by EGL NATIVE VISUAL TYPE (the actual sort order is
+   implementation-defined, depending on the meaning of native visual types).
+   11. Smaller EGL CONFIG ID (this is always the last sorting rule, and guarantees
+   a unique ordering).
+   EGLConfigs are not sorted with respect to the parameters
+   EGL BIND TO TEXTURE RGB, EGL BIND TO TEXTURE RGBA, EGL CONFORMANT,
+   EGL LEVEL, EGL NATIVE RENDERABLE, EGL MAX SWAP INTERVAL,
+   EGL MIN SWAP INTERVAL, EGL RENDERABLE TYPE, EGL SURFACE TYPE,
+   EGL TRANSPARENT TYPE, EGL TRANSPARENT RED VALUE,
+   EGL TRANSPARENT GREEN VALUE, and EGL TRANSPARENT BLUE VALUE.
+
+   3This rule places configs with deeper color buffers first in the list returned by eglChooseConfig.
+Applications may find this counterintuitive, and need to perform additional processing on the list of
+configs to find one best matching their requirements. For example, specifying RGBA depths of 5651
+could return a list whose first config has a depth of 8888.

+
+   3.1 Errors
+   Where possible, when an EGL function fails it has no side effects.
+   EGL functions usually return an indicator of success or failure; either an
+   EGLBoolean EGL TRUE or EGL FALSE value, or in the form of an out-of-band
+   return value indicating failure, such as returning EGL NO CONTEXT instead of a requested
+   context handle. Additional information about the success or failure of the
+   most recent EGL function called in a specific thread, in the form of an error code,
+   can be obtained by calling
+   EGLint eglGetError();
+   The error codes that may be returned from eglGetError, and their meanings,
+   are:
+   EGL SUCCESS
+   Function succeeded.
+   EGL NOT INITIALIZED
+   EGL is not initialized, or could not be initialized, for the specified display.
+   EGL BAD ACCESS
+   EGL cannot access a requested resource (for example, a context is bound in
+   another thread).
+   EGL BAD ALLOC
+   EGL failed to allocate resources for the requested operation.
+   9
+   10 CHAPTER 3. EGL FUNCTIONS AND ERRORS
+   EGL BAD ATTRIBUTE
+   An unrecognized attribute or attribute value was passed in an attribute list.
+   EGL BAD CONTEXT
+   An EGLContext argument does not name a valid EGLContext.
+   EGL BAD CONFIG
+   An EGLConfig argument does not name a valid EGLConfig.
+   EGL BAD CURRENT SURFACE
+   The current surface of the calling thread is a window, pbuffer, or pixmap that
+   is no longer valid.
+   EGL BAD DISPLAY
+   An EGLDisplay argument does not name a valid EGLDisplay; or, EGL
+   is not initialized on the specified EGLDisplay.
+   EGL BAD SURFACE
+   An EGLSurface argument does not name a valid surface (window, pbuffer,
+   or pixmap) configured for rendering.
+   EGL BAD MATCH
+   Arguments are inconsistent; for example, an otherwise valid context requires
+   buffers (e.g. depth or stencil) not allocated by an otherwise valid surface.
+   EGL BAD PARAMETER
+   One or more argument values are invalid.
+   EGL BAD NATIVE PIXMAP
+   An EGLNativePixmapType argument does not refer to a valid native
+   pixmap.
+   EGL BAD NATIVE WINDOW
+   An EGLNativeWindowType argument does not refer to a valid native
+   window.
+   EGL CONTEXT LOST
+   A power management event has occurred. The application must destroy all
+   contexts and reinitialise client API state and objects to continue rendering,
+   as described in section 2.6.
+   When there is no status to return (in other words, when eglGetError is called
+   as the first EGL call in a thread, or immediately after calling eglReleaseThread),
+   EGL SUCCESS will be returned.

+EGLDisplay eglGetDisplay(EGLNativeDisplayType
+display id);
+The type and format of display id are implementation-specific, and it describes a
+specific display provided by the system EGL is running on. For example, an EGL

+while an implementation under Microsoft Windows would require display id to be
+a Windows Device Context. If display id is EGL DEFAULT DISPLAY, a default

+   Use
+EGLBoolean eglChooseConfig(EGLDisplay dpy, const
+EGLint *attrib list, EGLConfig *configs,
+EGLint config size, EGLint *num config);
+to get EGLConfigs that match a list of attributes. The return value and the meaning
+of configs, config size, and num config are the same as for eglGetConfigs.
+However, only configurations matching attrib list, as discussed below, will be returned.
+On failure, EGL FALSE is returned. An EGL BAD ATTRIBUTE error is generated
+if attrib list contains an undefined EGL attribute or an attribute value that is
+unrecognized or out of range.
+All attribute names in attrib list are immediately followed by the corresponding
+desired value. The list is terminated with EGL NONE. If an attribute is not specified
+in attrib list, then the default value (listed in Table 3.4) is used (it is said to be
+specified implicitly). If EGL_DONT_CARE is specified as an attribute value, then the
+attribute will not be checked. EGL_DONT_CARE may be specified for all attributes
+except EGL LEVEL. If attrib list is NULL or empty (first attribute is EGL NONE),
+then selection and sorting of EGLConfigs is done according to the default criteria
+in Tables 3.4 and 3.1, as described below under Selection and Sorting.
+Selection of EGLConfigs
+Attributes are matched in an attribute-specific manner, as shown in the ”Selection
+Critera” column of table 3.4. The criteria listed in the table have the following
+meanings:
+AtLeast Only EGLConfigs with an attribute value that meets or exceeds the
+specified value are selected.
+Exact Only EGLConfigs whose attribute value equals the specified value are
+matched.
+Mask Only EGLConfigs for which the bits set in the attribute value include all
+the bits that are set in the specified value are selected (additional bits might
+be set in the attribute value).
+Special As described for the specific attribute.
+Some of the attributes must match the specified value exactly; others, such as
+EGL RED SIZE, must meet or exceed the specified minimum values.
+To retrieve an EGLConfig given its unique integer ID, use the
+EGL CONFIG ID attribute. When EGL CONFIG ID is specified, all other attributes
+are ignored, and only the EGLConfig with the given ID is returned.
+If EGL MAX PBUFFER WIDTH, EGL MAX PBUFFER HEIGHT,
+EGL MAX PBUFFER PIXELS, or EGL NATIVE VISUAL ID are specified in
+attrib list, then they are ignored (however, if present, these attributes must still be
+Version 1.3 - December 4, 2006
+3.4. CONFIGURATION MANAGEMENT 21
+followed by an attribute value in attrib list). If EGL SURFACE TYPE is specified
+in attrib list and the mask that follows does not have EGL WINDOW BIT set, or if
+there are no native visual types, then the EGL NATIVE VISUAL TYPE attribute is
+ignored.
+If EGL TRANSPARENT TYPE is set to EGL NONE in attrib list, then
+the EGL TRANSPARENT RED VALUE, EGL TRANSPARENT GREEN VALUE, and
+EGL TRANSPARENT BLUE VALUE attributes are ignored.
+If EGL MATCH NATIVE PIXMAP is specified in attrib list, it must be followed
+by an attribute value which is the handle of a valid native pixmap. Only
+EGLConfigs which support rendering to that pixmap will match this attribute2.
+If no EGLConfig matching the attribute list exists, then the call succeeds, but
+num config is set to 0.

+
+2 The special match criteria for EGL MATCH NATIVE PIXMAP was introduced due to the

+depths.
+3This rule places configs with deeper color buffers first in the list returned by eglChooseConfig.
+Applications may find this counterintuitive, and need to perform additional processing on the list of
+configs to find one best matching their requirements. For example, specifying RGBA depths of 5651
+could return a list whose first config has a depth of 8888.
+
+   Implementation notes:
+
+   Configurations are not always returned in the same order; the sort order depends on
+   whether we care about EGL_RED_SIZE, EGL_GREEN_SIZE, etc. So we need to extract the information
+   about which of these we care about, then pass this to a sorting function.

+  * \section intro_sec Introduction
+  *
+  * MMAL (Multi-Media Abstraction Layer) is a framework which is used to provide a host-side,
+  * simple and relatively low-level interface to multimedia components running on VideoCore.
+  * It also provides a component interface so that new components can be easily created and
+  * integrated into the framework.
+  *
+  * There is no requirement that all the components be running on VideoCore as MMAL doesn't
+  * put any restriction on where components live. The current implementation for instance
+  * provides some components which can be run on both host-side or VideoCore (e.g. the splitter
+  * component).
+  *
+  * \section features Features
+  *
+  * The MMAL API has been designed to support all the following features:
+  * - Sufficiently generic to support different kinds of multimedia component.
+  * - Simple to use from client side (mostly synchronous except where it matters).
+  * - Straightforward API for designing components (e.g. avoids multiple data paths, as found in RIL).
+  * - Allows for fully-optimised implementation of components (e.g. zero-copy buffer passing).
+  * - Portability (API is self-contained).
+  * - Supports multiple instances (e.g. of VideoCore).
+  * - Extensible without breaking source or binary backward compatibility.
+  *
+  * \section concepts API concepts
+  *
+  * The MMAL API is based on the concept of components, ports and buffer headers.
+  * Clients create MMAL components which expose ports for each individual
+  * elementary stream of data they support (e.g. audio/video). Components expose
+  * input ports to receive data from the client, and expose output ports
+  * to return data to the client.
+  *
+  * Data sent to or received from the component needs to be attached to a buffer header.
+  * Buffer headers are necessary because they contain buffer specific ancillary data which is
+  * necessary for the component and client to do their processing (e.g timestamps).
+  *
+  * \section comp Components
+  *
+  * MMAL lets clients create multi-media components (video encoders,
+  * video decoders, camera, and so-on) using a common API. Clients exchange
+  * data with components using buffer headers. A buffer header
+  * has a pointer to the payload data.
+  * Buffer headers are sent to and received from ports that are provided by components.
+  *
+  * A typical decoder component would have a single input port and a
+  * single output port, but the same architecture could also be used
+  * for components with different layouts (e.g. a camera with a
+  * capture and preview port, or a debugging component with just an input port).
+  *
+  * \subsection create Component Creation
+  *
+  * Each component is identified by a unique name. To create a specific component
+  * the client needs to call \ref mmal_component_create with the desired component's
+  * name as an argument.
+  * This call will return a context (\ref MMAL_COMPONENT_T) to the component. This
+  * context will expose the input and output ports (\ref MMAL_PORT_T) supported
+  * by this specific component.
+  *
+  * \note All VideoCore components have a name starting with the "vc." prefix (this prefix
+  * is used to distinguish when a creation request needs to be forwarded to VideoCore).
+  *
+  * \section port Component Ports
+  *
+  * A port (\ref MMAL_PORT_T) is the entity which exposes an elementary stream
+  * (\ref MMAL_ES_FORMAT_T) on a component. It is also the entity to which buffer headers
+  * (\ref MMAL_BUFFER_HEADER_T) are sent or from which they are received.
+  *
+  * Clients do not need to create ports. They are created automatically by
+  * the component when this one is created but the format of a port might need to
+  * be set by the client depending on the type of component the client is using.
+  *
+  * For example, for a video decoding component, one input port and one output port
+  * will be available. The format of the input port must be set by the
+  * client (using \ref mmal_port_format_commit) while the format of the output port
+  * will be automatically set by the component once the component has enough information
+  * to find out what its format should be.
+  *
+  * If the input port format contains enough information for the component to determine
+  * the format of the output port straight away, then the output port will be set to the proper
+  * format when \ref mmal_port_format_commit returns. Otherwise the output format will be set to
+  * \ref MMAL_ENCODING_UNKNOWN until the component is fed enough data to determine the format
+  * of the output port.
+  * When this happens, the client will receive an event on the output port, signalling
+  * that its format has changed.
+  *
+  * \section buf Buffer Headers
+  *
+  * Buffer headers (\ref MMAL_BUFFER_HEADER_T) are used to exchange data with components.
+  * They do not contain the data directly but instead contain a pointer to the data being
+  * transferred.
+  *
+  * Separating the buffer headers from the payload means that the memory for the data can
+  * be allocated outside of MMAL (e.g. if it is supplied by an external library) while still
+  * providing a consistent way to exchange data between clients and components.
+  *
+  * Buffer headers are allocated from pools and are reference counted. The refcount
+  * will drop when \ref mmal_buffer_header_release is called and the buffer header
+  * will be recycled to its pool when it reaches zero.
+  * The client can be notified when the buffer header is recycled so that it can recycle the
+  * associated payload memory as well.
+  *
+  * A pool of buffer headers should be created after committing the format of the port. When
+  * the format is changed, the minimum and recommended size and number of buffers may change.
+  *
+  * \note The current number of buffers and their size (\ref MMAL_PORT_T::buffer_num and \ref
+  * MMAL_PORT_T::buffer_size) are not modified by MMAL, and must be updated by the client as
+  * required after changes to a port's format.
+  *
+  * \subsection queue Queues of Buffer Headers
+  *
+  * Queues (\ref MMAL_QUEUE_T) are a facility that allows thread-safe processing of buffer headers
+  * from the client. Callbacks triggered by a MMAL component when it sends a buffer header to the
+  * client can simply put the buffer in a queue and let the main processing thread of the client
+  * get its data from the queue.
+  *
+  * \subsection pool Pools of Buffer Headers
+  *
+  * Pools (\ref MMAL_POOL_T) let clients allocate a fixed number of buffer headers, and 
+  * a queue (\ref MMAL_QUEUE_T). They are used for buffer header allocation.
+  * Optionally a pool can also allocate the payload memory for the client.
+  *
+  * Pools can also be resized after creation, for example, if the port format is changed leading
+  * to a new number or size of buffers being required.
+  *
+  * \section param Port Parameters
+  *
+  * Components support setting and getting component specific parameters using
+  * \ref mmal_port_parameter_set and \ref mmal_port_parameter_get. Parameters
+  * are identified using an integer index; parameter data is binary. See the \ref MMAL_PARAMETER_IDS
+  * "Pre-defined MMAL parameter IDs" page for more information on the pre-defined parameters.
+  *
+  * \section events Port Events
+  *
+  * Components can generate events on their ports. Events are sent to clients
+  * as buffer headers and thus when the client receives a buffer header on one
+  * of the component's port it should check if the buffer header is an event
+  * and in which case process it and then release it (\ref mmal_buffer_header_release).
+  * The reason for transmitting events in-band with the actual data is that it
+  * is often very valuable to know exactly when the event happens relative to the
+  * the actual data (e.g. with a focus event, from which video frame are we in focus).\n
+  * Buffer headers used to transmit events are allocated internally by the framework
+  * so it is important to release the buffer headers with \ref mmal_buffer_header_release
+  * so the buffer headers make it back to their actual owner.
+  *
+  * Event buffer headers are allocated when the component is created, based on the
+  * minimum number and size of control port buffers set by the component. Component
+  * wide events (not port specific) are sent to the control port callback when that
+  * port is enabled. Port events are sent to the port callback, the same as data
+  * buffers, but the 'cmd' field is non-zero.
+  *
+  * \section version Versioning
+  *
+  * The API requires that the MMAL core be the same or more recent version
+  * as the components and clients. Clients and components can be older and
+  * the API will still work both at compile-time and run-time.
+  *
+  * \section example Example Code
+  *
+  * The following code is a simple example on how to do video decoding using MMAL. Note that
+  * the code is intended to be clear and illustrate how to use MMAL at its most fundamental
+  * level, not necessarily the most efficient way to achieve the same result. Use of opaque
+  * images, tunneling and zero-copy inter-processor buffers can all improve the performance
+  * or reduce the load.
+  *
+  * The \ref MmalConnectionUtility "Port Connection Utility" functions can also be used to
+  * replace much of the common "boilerplate" code, especially when a pipeline of several
+  * components needs to be processed.
+  *
+  * \code
+  * #include <mmal.h>
+  * ...
+  * static void input_callback(MMAL_PORT_T *port, MMAL_BUFFER_HEADER_T *buffer)
+  * {
+  *    // The decoder is done with the data, just recycle the buffer header into its pool
+  *    mmal_buffer_header_release(buffer);
+  * }
+  * static void output_callback(MMAL_PORT_T *port, MMAL_BUFFER_HEADER_T *buffer)
+  * {
+  *    MMAL_QUEUE_T *queue = (MMAL_QUEUE_T *)port->userdata;
+  *    mmal_queue_put(queue, buffer); // Queue the decoded video frame
+  * }
+  * ...
+  *
+  * MMAL_COMPONENT_T *decoder = 0;
+  * MMAL_STATUS_T status;
+  *
+  * // Create the video decoder component on VideoCore

+/** \defgroup MmalClock Clock Framework
+ * The MMAL clock framework provides scheduling facilities to the rest of
+ * MMAL.
+ *
+ * The framework consists mainly of clock ports and a clock module. Client
+ * applications and components interact directly with clock ports, while
+ * the clock module is only used internally by clock ports.
+ *
+ * Clock ports ensure that the local media-time for each component is
+ * synchronised across all components. This is done by passing buffers between
+ * clock ports which contain clock-specific data.
+ *
+ * One clock port will normally act as the reference clock for the rest of the
+ * system. This is usually chosen to be the clock port of the audio render
+ * component, but is configurable by the client and could potentially be any
+ * other clock port (or even the client application itself).
+ *
+ * Components that are responsible for timed delivery of frames, do so by
+ * registering callback requests for a particular time-stamp with the clock
+ * port. These requests are scheduled using the clock module which maintains
+ * an internal media-time.
+ *
+ * The clock framework also provides the ability to perform playback at different
+ * speeds. This is achieved with a clock scale factor which determines the speed
+ * at which the media-time advances relative to real-time, with:
+ *   scale = 1.0 -> normal playback speed
+ *   scale = 0   -> playback paused
+ *   scale > 1.0 -> fast-forward
+ *   scale < 1.0 -> slow motion

+/** \defgroup MmalConnectionUtility Port connection utility
+ * \ingroup MmalUtilities
+ * The port connection utility functions can be used in place of common sequences
+ * of calls to the MMAL API in order to process buffers being passed between two
+ * ports.
+ *
+ * \section ProcessingConnectionBufferHeaders Processing connection buffer headers
+ * Either in response to the client callback function being called, or simply on a
+ * timer, the client will need to process the buffer headers of the connection
+ * (unless tunneling is used).
+ *
+ * Buffer headers that are in the pool queue will need to be sent to the output port,
+ * while buffer headers in the connection queue are sent to the input port. The
+ * buffer headers in the connection queue may contain pixel data (the cmd field is
+ * zero) or an event (the cmd field is non-zero). In general, pixel data buffer
+ * headers need to be passed on, while event buffer headers are released. In the
+ * case of the format changed event, mmal_connection_event_format_changed() can be
+ * called before the event is released.
+ *
+ * Other, specialized use cases may also be implemented, such as getting and
+ * immediately releasing buffer headers from the connection queue in order to
+ * prevent their propagation. This could be used to drop out video, for example.
+ *
+ * \section TunnellingConnections Tunnelling connections
+ * If the \ref MMAL_CONNECTION_FLAG_TUNNELLING flag is set when the connection is
+ * created, MMAL tunneling will be used. This automates the passing of the buffer
+ * headers between the output port and input port, and back again. It will also do
+ * this as efficiently as possible, avoiding trips between the ARM and the VideoCore
+ * if both components are implemented on the VideoCore. The consequence of this is
+ * that there is no client callback made as buffer headers get transferred.
+ *
+ * The client can still monitor the control port of a component (usually a sink
+ * component, such as video_render) for the end of stream, in order to know when to
+ * dismantle the connection.
+ *
+ * \section ConnectionClientCallback Client callback
+ * When not using tunnelling, the client callback function is called each time a
+ * buffer arrives from a port (either input or output).
+ *
+ * \note The callback is made on a different thread from the one used by the
+ * client to set up the connection, so care must be taken with thread safety.
+ * One option is to raise a signal to the main client thread that queue processing
+ * needs to be done, another is for the callback to perform the queue processing
+ * itself.
+ *
+ * The client can also store an opaque pointer in the connection object, which is
+ * never used by the MMAL code and is only meaningful to the client.

+/*=============================================================================
+VideoCore OS Abstraction Layer - public header file
+=============================================================================*/
+
+/**
+  * \mainpage OS Abstraction Layer
+  *
+  * \section intro Introduction
+  *
+  * This abstraction layer is here to allow the underlying OS to be easily changed (e.g. from
+  * Nucleus to ThreadX) and to aid in porting host applications to new targets.
+  *
+  * \subsection error Error handling
+  *
+  * Wherever possible, VCOS functions assert internally and return void. The only exceptions
+  * are creation functions (which might fail due to lack of resources) and functions that
+  * might timeout or fail due to lack of space. Errors that might be reported by the underlying
+  * OS API (e.g. invalid mutex) are treated as a programming error, and are merely asserted on.
+  *
+  * \section thread_synch Threads and synchronisation
+  *
+  * \subsection thread Threads
+  *
+  * The thread API is somewhat different to that found in Nucleus. In particular, threads
+  * cannot just be destroyed at arbitrary times and nor can they merely exit. This is so
+  * that the same API can be implemented across all interesting platforms without too much
+  * difficulty. See vcos_thread.h for details. Thread attributes are configured via
+  * the VCOS_THREAD_ATTR_T structure, found in vcos_thread_attr.h.
+  *
+  * \subsection sema Semaphores
+  *
+  * Counted semaphores (c.f. Nucleus NU_SEMAPHORE) are created with VCOS_SEMAPHORE_T.
+  * Under ThreadX on VideoCore, semaphores are implemented using VideoCore spinlocks, and
+  * so are quite a lot faster than ordinary ThreadX semaphores. See vcos_semaphore.h.
+  *
+  * \subsection mtx Mutexes
+  *
+  * Mutexes are used for locking. Attempts to take a mutex twice, or to unlock it
+  * in a different thread to the one in which it was locked should be expected to fail.
+  * Mutexes are not re-entrant (see vcos_reentrant_mutex.h for a slightly slower
+  * re-entrant mutex).
+  *
+  * \subsection evflags Event flags
+  *
+  * Event flags (the ThreadX name - also known as event groups under Nucleus) provide
+  * 32 flags which can be waited on by multiple clients, and signalled by multiple clients.
+  * A timeout can be specified. See vcos_event_flags.h. An alternative to this is the
+  * VCOS_EVENT_T (see vcos_event.h) which is akin to the Win32 auto-reset event, or a
+  * saturating counted semaphore.
+  *
+  * \subsection event Events
+  *
+  * A VCOS_EVENT_T is a bit like a saturating semaphore. No matter how many times it
+  * is signalled, the waiter will only wake up once. See vcos_event.h. You might think this
+  * is useful if you suspect that the cost of reading the semaphore count (perhaps via a
+  * system call) is expensive on your platform.
+  *
+  * \subsection tls Thread local storage
+  *
+  * Thread local storage is supported using vcos_tls.h. This is emulated on Nucleus
+  * and ThreadX.
+  *
+  * \section int Interrupts
+  *
+  * The legacy LISR/HISR scheme found in Nucleus is supported via the legacy ISR API,
+  * which is also supported on ThreadX. New code should avoid this, and old code should
+  * be migrated away from it, since it is slow. See vcos_legacy_isr.h.
+  *
+  * Registering an interrupt handler, and disabling/restoring interrupts, is handled
+  * using the functions in vcos_isr.h.
+  *
+  */
+
+/**
+  * \file vcos.h
+  *
+  * This is the top level header file. Clients include this. It pulls in the platform-specific
+  * header file (vcos_platform.h) together with header files defining the expected APIs, such
+  * as vcos_mutex.h, vcos_semaphore.h, etc. It is also possible to include these header files
+  * directly.

+
+/*
+ * Macro:
+ *    vcos_assert(cond)
+ *    vcos_assert_msg(cond, fmt, ...)
+ * Use:
+ *    Detecting programming errors by ensuring that assumptions are correct.
+ * On failure:
+ *    Performs a platform-dependent "breakpoint", usually with an assert-style
+ *    message. The '_msg' variant expects a printf-style format string and
+ *    parameters.
+ *    If a failure is detected, the code should be fixed and rebuilt.
+ * In release builds:
+ *    Generates no code, i.e. does not evaluate 'cond'.
+ * Returns:
+ *    Nothing.
+ *
+ * Macro:
+ *    vcos_demand(cond)
+ *    vcos_demand_msg(cond, fmt, ...)
+ * Use:
+ *    Detecting fatal system errors that require a reboot.
+ * On failure:
+ *    Performs a platform-dependent "breakpoint", usually with an assert-style
+ *    message, then calls vcos_abort (see below).
+ * In release builds:
+ *    Calls vcos_abort() if 'cond' is false.
+ * Returns:
+ *    Nothing (never, on failure).
+ *
+ * Macro:
+ *    vcos_verify(cond)
+ *    vcos_verify_msg(cond, fmt, ...)
+ * Use:
+ *    Detecting run-time errors and interesting conditions, normally within an
+ *    'if' statement to catch the failures, i.e.
+ *       if (!vcos_verify(cond)) handle_error();
+ * On failure:
+ *    Generates a message and optionally stops at a platform-dependent
+ *    "breakpoint" (usually disabled). See vcos_verify_bkpts_enable below.
+ * In release builds:
+ *    Just evaluates and returns 'cond'.
+ * Returns:
+ *    Non-zero if 'cond' is true, otherwise zero.
+ *
+ * Macro:
+ *    vcos_static_assert(cond)
+ * Use:
+ *    Detecting compile-time errors.
+ * On failure:
+ *    Generates a compiler error.
+ * In release builds:
+ *    Generates a compiler error.
+ *
+ * Function:
+ *    void vcos_abort(void)
+ * Use:
+ *    Invokes the fatal error handling mechanism, alerting the host where
+ *    applicable.
+ * Returns:
+ *    Never.
+ *
+ * Macro:
+ *    VCOS_VERIFY_BKPTS
+ * Use:
+ *    Define in a module (before including vcos.h) to specify an alternative
+ *    flag to control breakpoints on vcos_verify() failures.
+ * Returns:
+ *    Non-zero values enable breakpoints.
+ *
+ * Function:
+ *    int vcos_verify_bkpts_enable(int enable);
+ * Use:
+ *    Sets the global flag controlling breakpoints on vcos_verify failures,
+ *    enabling the breakpoints iff 'enable' is non-zero.
+ * Returns:
+ *    The previous state of the flag.
+ *
+ * Function:
+ *    int vcos_verify_bkpts_enabled(void);
+ * Use:
+ *    Queries the state of the global flag enabling breakpoints on vcos_verify
+ *    failures.
+ * Returns:
+ *    The current state of the flag.
+ *
+ * Examples:
+ *
+ * int my_breakpoint_enable_flag = 1;
+ *
+ * #define VCOS_VERIFY_BKPTS my_breakpoint_enable_flag
+ *
+ * #include "interface/vcos/vcos.h"
+ *
+ * vcos_static_assert((sizeof(object) % 32) == 0);
+ *
+ * // ...
+ *
+ *    vcos_assert_msg(postcondition_is_true, "Coding error");
+ *
+ *    if (!vcos_verify_msg(buf, "Buffer allocation failed (%d bytes)", size))
+ *    {
+ *       // Tidy up
+ *       // ...
+ *       return OUT_OF_MEMORY;

+ * Logging support
+ *
+ * This provides categorised logging. Clients register
+ * a category, and then get a number of logging levels for
+ * that category.
+ *
+ * The logging level flag is tested using a flag *before* the
+ * function call, which makes logging very fast when disabled - there
+ * is no function call overhead just to find out that this log
+ * message is disabled.
+ *
+ * \section VCOS_LOG_CATEGORY
+ *
+ * As a convenience, clients define VCOS_LOG_CATEGORY to point to
+ * their category; the various vcos_log_xxx() macros then expand to
+ * use this.
+ *
+ * e.g.
+ *
+ *     #define VCOS_LOG_CATEGORY (&my_category)
+ *
+ *     #include <interface/vcos/vcos.h>
+ *
+ *     VCOS_LOG_CAT_T my_category;

+ * \file vcos_thread.h
+ *
+ * \section thread Threads
+ *
+ * Under Nucleus, a thread is created by NU_Create_Task, passing in the stack
+ * and various other parameters. To stop the thread, NU_Terminate_Thread() and
+ * NU_Delete_Thread() are called.
+ *
+ * Unfortunately it's not possible to emulate this API under some fairly common
+ * operating systems. Under Windows you can't pass in the stack, and you can't
+ * safely terminate a thread.
+ *
+ * Therefore, an API which is similar to the pthreads API is used instead. This
+ * API can (mostly) be emulated under all interesting operating systems.
+ *
+ * Obviously this makes the code somewhat more complicated on VideoCore than it
+ * would otherwise be - we end up with an extra mutex per thread, and some code
+ * that waits for it. The benefit is that we have a single way of creating
+ * threads that works consistently on all platforms (apart from stack supplying).
+ *
+ * \subsection stack Stack
+ *
+ * It's still not possible to pass in the stack address, but this can be made
+ * much more obvious in the API: the relevant function is missing and the
+ * CPP symbol VCOS_CAN_SET_STACK_ADDR is zero rather than one.
+ *
+ * \subsection thr_create Creating a thread
+ *
+ * The simplest way to create a thread is with vcos_thread_create() passing in a
+ * NULL thread parameter argument. To wait for the thread to exit, call
+ * vcos_thread_join().
+ *
+ * \subsection back Backward compatibility
+ *
+ * To ease migration, a "classic" thread creation API is provided for code
+ * that used to make use of Nucleus, vcos_thread_create_classic(). The
+ * arguments are not exactly the same, as the PREEMPT parameter is dropped.

+/**
+ *  GCDWebServer provides its own built-in logging facility which is used by
+ *  default. It simply sends log messages to stderr assuming it is connected
+ *  to a terminal type device.
+ *
+ *  GCDWebServer is also compatible with a limited set of third-party logging
+ *  facilities. If one of them is available at compile time, GCDWebServer will
+ *  automatically use it in place of the built-in one.
+ *
+ *  Currently supported third-party logging facilities are:
+ *  - XLFacility (by the same author as GCDWebServer): https://github.com/swisspol/XLFacility
+ *
+ *  For the built-in logging facility, the default logging level is INFO
+ *  (or DEBUG if the preprocessor constant "DEBUG" evaluates to non-zero at
+ *  compile time).
+ *
+ *  It's possible to have GCDWebServer use a custom logging facility by defining
+ *  the "__GCDWEBSERVER_LOGGING_HEADER__" preprocessor constant in Xcode build
+ *  settings to the name of a custom header file (escaped like \"MyLogging.h\").
+ *  This header file must define the following set of macros:
+ *
+ *    GWS_LOG_DEBUG(...)
+ *    GWS_LOG_VERBOSE(...)
+ *    GWS_LOG_INFO(...)
+ *    GWS_LOG_WARNING(...)
+ *    GWS_LOG_ERROR(...)
+ *
+ *  IMPORTANT: These macros must behave like NSLog(). Furthermore the GWS_LOG_DEBUG()
+ *  macro should not do anything unless the preprocessor constant "DEBUG" evaluates
+ *  to non-zero.
+ *
+ *  The logging methods below send log messages to the same logging facility
+ *  used by GCDWebServer. They can be used for consistency wherever you interact
+ *  with GCDWebServer in your code (e.g. in the implementation of handlers).
+ */
