The patch looks good but there's one simple optimization that could be 
made.  If glRenderBufferStorage() is called with a new width/height 
but the internalFormat stays the same, we wouldn't have to invalidate 
the parent FBO(s).

I think changing the size of a renderbuffer would be more common than 
channging its format.
