Overridden from FOpenGLCommonState

		Name	Description
	void	CleanupResources()
	void	InitializeResources ( int32 NumCombinedTextures, int32 NumComputeUAVUnits )	AB: moved from the header, since it was causing linker error when the header is included externally.

Constants

Name	Description
MAX_UNIFORM_BUFFERS_PER_SHADER_STAGE	The RHI does not allow more than 14 constant buffers per shader stage due to D3D11 limits.
