Detailed Description
Render to texture support for OpenGL.
This class needs to make a number of assumptions due to the requirements and complexity of render to texture in OpenGL. 1) This class is only guaranteed to work with 2D textures or cubemaps. 3D textures may or may not work. 2) This class does not currently support multiple texture targets. Regardless of how many targets you bind, only Color0 will be used. 3) This class requires that the DepthStencil and Color0 targets have identical dimensions. 4) If the DepthStencil target is GFXTextureTarget::sDefaultStencil, then the Color0 target should be the same size as the current backbuffer and should also be the same format (typically R8G8B8A8)
