gregory.hainaut e80b002929 gsdx ogl: Flush various pending work
* try to use more subroutine on VS&PS, unfortunately hit a driver crash!
* Call Attach/DetachContext through GSDevice so I can unmap currently mapped buffer
* Implement glsl part of GL_ARB_bindless texture, again hit another driver crash!
* various fix of GL_ARB_buffer_storage. Basic benchmark show only improvement on 'cold' case, I guess it will improve smoothness
* try to fix GL_clear_texture, no success so far. It seem the extension is limited to basic texture (aka no depth/stencil)

gregory.hainaut e01c6cd9ce gsdx ogl: the proof of concept commit
* GL_ARB_shader_subroutine for perf
fix for nvidia => add missing shader declaration. Nvidia got +4fps on colin3 :) 

For the moment only 2 PS parameters are supported. Code need to be extended to support others games that often
switch shader program (like xenosaga).
require GL4 class hardware and the option override_GL_ARB_shader_subroutine = 1
Note: strangely on AMD linux it is slower!

* GL_ARB_shader_image_load_store for accuraccy (Date)
Use a signed integer texture and reenable color buffer writing

Current status: Amagami_transparency.gs & P3_battle_shadows.gs are now working on Nvidia with a small perf impact.
Current implementation detail:
1/ setup the standard stencil as before
2/ on remaining pixel, draw once to compute first primitive that will write a fail alpha value.
3/ final draw based on primitive id of step 2

Note: I think we would get a bad behavior if depth test&mask are enabled on step 2/3
Note2: on my limited testcase the perf impact was on CPU. It would be possible to merge step1&2 to nullifying it (could 
even be faster actually), however it would require more GPU power.

Again require GL4 class hardware. And the option UserHacks_DateGL4 = 1

gregory.hainaut 07605941ef gsdx ogl:
* some preliminary work to test/benchmark bindless texture in the future (glsl was not yet updated)
Bindless texture allow to get a GPU texture pointer and then set it directly
to the shader as a basic uniform.
=> no more texture unit selection/validation
=> no more texture validation neither texture hash lookup

3rdparty: update gl header to the latest gl4.4

gregory.hainaut b4084047be gsdx ogl: Used a basic flat interpolation for color interpolation (line & tri primitives)
Card that support gs:
remain only a gs to generate sprite from a line. Even dummy gs are costly for the GPU.

Card that don't support gs:
remove useless copy of color for line and triangle primitives

Note for dx: opengl 3.2 (maybe not gles) supports both flat interpolation
convention (GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION).  It might
be possible to shuffle vertex index to put the last vertex in first position.

- buff[0] = head + 0;
- buff[1] = head + 1;
- buff[2] = head + 2;
+ buff[0] = head + 2;
+ buff[1] = head + 1;
+ buff[2] = head + 0;

gregory.hainaut 0f603a98d5 gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension
The idea was to replace shader program swith by pointer function calls inside
shaders.  At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.

If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.

Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)

gregory.hainaut a46b489a24 gsdx ogl: various minor optimization.
* move most of gl states into a separate namespace. Extend it to depth/stencil/blend micro state
=> save 10,000 opengl call by frame for colin mcrae 3
* Only setup blend state of first drawbuffer
* Don't request anymore a debug context on dev/release build

gregory.hainaut 64f783410e gsdx ogl:
* preliminary work for GL4.4 extensions (ARB_clear_texture & ARB_multi_bind). Disabled until I got a 4.4 driver
Note: I plan also to use ARB_buffer_storage
* compute texture gl option in the constructor (avoid a couple of swith case)
* redo texture unit management. Unit 0-2 for shaders, Unit 3 for texture operations. MultiBind will allow to bind 
shader input without disturbing texture binding points.

gregory.hainaut d3e1e4da0d gsdx ogl:
* allow to switch renderer with F9
* skip first frame in stat of the replayer
* drop msaa. Fxaa and internal resolution will do the job
* move texture attachment from texture object into device object (allow to keep sanely the state)
* split the write buffer and attachment setup
* completely split sampler and texture input setup
* redo GSDeviceOGL::CopyOffscreen to avoid an extra copy.

* fix gcc warning in GSVector.h
* fix memory leak of GSDeviceOGL.m_shader

gregory.hainaut ca1edbf2cb gsdx ogl:
* Separate state and shader compilation into separate function
* replace various hash_map by basic array
* Compact VertexScale and offset into a single vec4
* add the new option "ogl_vertex_subdata": subdata is faster on FGLRX, test are welcome on Nvidia drivers
    0 => use map/unmap
    1 => use subdata

replay: add "linux_replay" option and compute some nice stat (mean, standard deviation)

cmake: recreate shader header at build time

* Use a basic context on EGL. Allow to use Mesa 9.1 on AMD GPU.

* Try harder to detect FGLRX driver on window
* various clean

Remain to fix the coordinate system for upscaling

gregory.hainaut 75418aba43 gsdx-ogl-wnd:
* Emulate Geometry Shader from the CPU.
* add some option to override opengl extension detection
* redo shader interface (again) to compile on the free driver

SW renderer is now working on the free driver.

To test it on your linux box use this cmake option -DEGL_API=TRUE
Note: (need opengl 3.0) I test mesa 9.2 git
