OpenGL.GL.EXT.blend_func_separate

OpenGL extension EXT.blend_func_separate

This module customises the behaviour of the OpenGL.raw.GL.EXT.blend_func_separate to provide a more Python-friendly API

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://www.opengl.org/registry/specs/EXT/blend_func_separate.txt
