Gregory Hainaut d37cc8e1e7 gsdx-ogl: GL_ARB_shading_language_420pack is now mandatory
All API/drivers support it so time to remove the fallback.

Gregory Hainaut 594f6c33a2 gsdx-ogl-ES: require GL_EXT_shader_io_blocks + GLES3.1
Allow to use same shader interface for all API

Note: on the GL API it will require GL3.3 (see next commit)

gregory.hainaut f5257b2c3c gsdx ogl: don't rely on GL_ES builtin (3 differents implementations...). Hopefully fix Linux Intel GPU.

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 bd5f379044 gsdx ogl:
* 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

gregory.hainaut a764950468 gsdx ogl:
* replace vertex interface with block interface. It avoid to depends on the ARB_sso extension.
* disable geometry shader on Nvidia & Linux. Slower but better than a black screen !
* default logz to 1, avoid some glitches.

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

gregory.hainaut aafa7a088a gsdx-ogl-wnd:
* fix a bad interaction when GL_ARB_SSO is supported without GL_ARB_shading_language_420pack
* try to replace struct with flat parameter in glsl interface
=> with some hacks of the free driver, I was able to compile SW renderer shader. Unfortunately
   the rendering is broken. Maybe my hack :p
* remove EGL context check (wasn't working as expected)

gregory.hainaut c9b3dcf581 gsdx-ogl-wnd:
* 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...

gregory.hainaut 08329122aa gsdx (ogl):
* Use bigger index for Uniform buffer to avoid any collision with sampler. 
* add a new config to disable openGL 4.2 requirement. Would be done at runtime later.

* various cosmetic change

gregory.hainaut fbb224837d gsdx-ogl: LINUX-ONLY
* Enable interlace feature. (note I'm well aware that interlace crashes with SDL)
* remove useless callback debug function
* handle the y axis differently. Move vertex to follow right-hand system (render everything in reverse) then flip the y-axis for the screen rendering

gregory.hainaut a835de0af7 gsdx-ogl: LINUX-ONLY
* implement the saving of texture (take bmp SW code)
* fix the missing "enable attribute code" and the typo in glsl. It works now !!!
* rework a little texture to pack texture into a temporay buffer when src pitch != dst pitch
* try to replace sdl with pure xlib (not yet enabled by default but it seems to work)

Note there still a minor issue, coordinate are different between DX and OGL (upper-left vs lower-left) so the image is inversed.

gregory.hainaut eb3eafa090 gsdx-ogl:
* implement shader code (subset that seem to be used in SW mode)
* some hack to fix some alignment issue with GSVertexPT1 structure
* Lots of various opengl fixes. Remaining unsupported GL feature are inside SDL.

gregory.hainaut 6125baa578 gsdx-ogl:
* make a rough implementation of most of the opengl device interface. Only a savestate nothing to expect yet.
* depend of libglew 1.6 (normally 1.7 but I manually defined the only missing function)
