A thin wrapper for OpenGL framebuffer objets. For implementation use only
Bases: object
Wrapper for framebuffer objects. See
http://oss.sgi.com/projects/ogl-sample/registry/EXT/framebuffer_object.txt

Set FBO as current rendering target
Check that currently set framebuffer is ready for rendering
Map currently bound framebuffer (not necessarily self) to texture
Set default framebuffer as current rendering target
