'''OpenGL extension EXT.blend_func_separate

Overview (from the spec)
	
	Blending capability is extended by defining a function that allows
	independent setting of the RGB and alpha blend factors for blend
	operations that require source and destination blend factors.  It
	is not always desired that the blending used for RGB is also applied
	to alpha.

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