'''OpenGL extension EXT.framebuffer_blit

Overview (from the spec)
	
	This extension modifies EXT_framebuffer_object by splitting the
	framebuffer object binding point into separate DRAW and READ
	bindings.  This allows copying directly from one framebuffer to
	another.  In addition, a new high performance blit function is
	added to facilitate these blits and perform some data conversion
	where allowed.

The official definition of this extension is available here:
	http://oss.sgi.com/projects/ogl-sample/registry/EXT/framebuffer_blit.txt
