OpenGL: Remove FFP built-in vertex variables (gl_Vertex, gl_Color...)
OpenGL: Remove FFP built-in vertex variables (gl_Vertex, gl_Color...) from glsl
OpenGL Fix: Remove FFP built-in vertex variables (gl_Vertex, gl_Color...)
OpenGL Remove: FFP deprecated functions.
OpenGL: Clean glsl files
OpenGL: Clean code
OpenGL: Add GLEW
OpenGL: Add GL_KHR_debug extension
OpenGL: Add GL_KHR_debug extension
OpenGL: Improve GFXGLWindowTarget::resolveTo performance
OpenGL: Add GL_EXT_direct_state_access for vertext/primitive buffers
OpenGL Fix: GFXGLOcclusionQuery::getStatus not check if query is valid
OpenGL: Use GL_KHR_debug on debug builds
OpenGL Fix: GFXGLVertexBuffer::lock not set lockedVertexPtr
OpenGL Fix: Modify FBO are very expensive.
OpenGL Fix: Error with vertex attribute declaration on cloudLayerV.glsl.
OpenGL: Use wglCreateContextAttribsARB if possible for create context
OpenGL: GFXGLWindowTarget use GFXGLDevice's OpenGL context. This fix lots of state changes.
OpenGL: Reduce Sampler state changes.
OpenGL: Changes for prepare GFXGLDevice profiler.
