Split code in 2 parts
* Base class (GSWndEGL) that implement the core EGL and GL context
* Derived class (GSWndEGL_X11/GSWndEGL_WL) that implement the backend to handle native resources
Note: Most backend code is only useful for GSopen1/PS1 mode. GSopen2 only requires
the AttachNativeWindow implementation
Code is based around EGL_EXT_platform extension that allow to select the platform at runtime.
Note: I think the extension was integrated in EGL 1.5
The X11 backend was mostly converted to XCB
The wayland backend is only a placeholder for future code
I don't know if MS windows is/could be supported with EGL_EXT_platform API
Code validated on Mesa. Proprietary drivers aren't yet tested.
* require a 3.1 context
* unattach texture of the fbo when they're not used
(avoid to have a texture and depth_stencil with different size)
Note: except minor shader bug it works on Nvidia 340.23.01
* Fix to create a 3.0 GLES context
* set a default precision to fix most of shader compilation issue
* Crash later because of GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT
=> need to test opensource driver
* 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
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5713 96395faa-99c1-11dd-bbfe-3dabce05a288
* clean extension management and fix compilation of previous gl44 code.
* Use pixel buffer object to upload texture data.
=> avoid crash on AMD driver
=> a bit faster and probably got some margins for the future
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5712 96395faa-99c1-11dd-bbfe-3dabce05a288
* uniform was wrongly set before the activation of the program (free driver only)
* Always use only 1 drawbuffer. Easier besides previous setup was wrong for convert:ps_main1
GLES trial (v3):
* add the cmake option GLES_API. Note library (libgles) are hardcoded for the moment
* Disable opengl check
* Disable gl_GetDebugMessageLogARB not supported!
* Emulate gl_DrawElementsBaseVertex, add manually the index offset (surely slow but work)
* Fix hundred of shader error (no implicit cast of integer to float...)
Unfortunately GLES doesn't support dual blending so no blend in hardware renderer. Otherwise it is fine
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5700 96395faa-99c1-11dd-bbfe-3dabce05a288
* try to setup advance gl context attribute. If driver doesn't support it fallback to the default.
zzogl:
* use glsl2h to generate an header shader as GSdx. Much easier to install
* Get GSUniformBufferOGL & GSVertexArrayOGL speed improvement from GSdx
cmake:
* detect current gcc version. Yield a warning if < 4.7 or an error if < 4.5
glsl2h:
* support zzogl too
* compute md5sum to avoid useless relink
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5696 96395faa-99c1-11dd-bbfe-3dabce05a288
* fix shader compilation on Nvidia (broken on r5682)
* fix various memory leak thanks to Valgrind
Cmake: fix a minor typo
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5688 96395faa-99c1-11dd-bbfe-3dabce05a288
* don't delete the wnd in GSclose. It can still be used later
* Properly detect the GL_ARB_gpu_shader5 extension for Fxaa
* A couple of fix in Create (GSopen1) of GSWndEGL/GSWndOGL
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5674 96395faa-99c1-11dd-bbfe-3dabce05a288
* add exception in GSWndEGL and GSWndOGL
* Try to use EGL when GLX failed => you don't need any flags for the opensource driver ;)
cmake: don't install anymore the glsl shader
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5671 96395faa-99c1-11dd-bbfe-3dabce05a288
gsdx:
* move gl function loading into GSwnd. Clean the header and avoid to rely on macro.
* Always require libegl for GSdx. You still need to select the API at compilation.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5670 96395faa-99c1-11dd-bbfe-3dabce05a288
* factorize sample object creation
* remember frame buffer attachment state
* Use a basic context on EGL. Allow to use Mesa 9.1 on AMD GPU.
* precompile vertex and geometry shader to avoid benchmark polution on replay
* Try harder to detect FGLRX driver on window
* various clean
Remain to fix the coordinate system for upscaling

* Fix shader alpha issue. Hoppefully fix lots of glitches.
* Use glBufferSubData to upload data into the constant buffer instead of map/unmap. More fps :)
* Fix wrong api setup on EGL
* Be more portable on glsl2h
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5650 96395faa-99c1-11dd-bbfe-3dabce05a288
* clean texture management & use different texture unit for various texture operation
* separate sampler and texture setup
* Always disable GL_SCISSOR_TEST before any cleaning to be sure the all pixels are reset
* properly set upscale_multiplier in the linux gui (was mixed with msaa). Unfortunately it is still broken...
* Fix EGL with GSopen1
* Use stdcall for function definition in the replay (avoid segmentation fault)
* Directly use gl_Position in shader instead of an extra user defined variable
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5648 96395faa-99c1-11dd-bbfe-3dabce05a288
* fix wrong interaction when both GL41 or GL42 aren't supported
* Add a new define to downgrade opengl requirement to test the free driver and EGL
=> As far as I can tell, they only miss geometry shader& GLSL150 (got GLSL140)
* Found a way to avoid crash in AMD driver. Skip the upload of small texture but rendering is wrong now...
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5643 96395faa-99c1-11dd-bbfe-3dabce05a288
* remove an old&useles dummy geometry shader (was used to workaround amd bug)
* use a basic X11 window for GSopen1
* redo the replayer: it is now based on dlopen rather than standard static/dynamic library. AMD driver doesn't play nicely with the later...

* initialize the context status variable that take care of some startup hang
* cmake: don't link and compile EGL when it isn't requested
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl-wnd@5528 96395faa-99c1-11dd-bbfe-3dabce05a288
* implement GSWndEGL copy/pasted from zzogl.
* remove linux debugging shader that failed to compile on window
* add additional debug message during context creation
