Yes, if you have an onscreen context already you can use FBOs to do RTT
passes which you then use in a final onscreen pass.
So that's what I meant - if your OpenGL app already creates a context,
there's no reason to create one (pbuffer or otherwise) just to be able
to use FBOs, you could create your FBOs in the existing context.
