'''OpenGL extension EXT.blend_equation_separate

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

Overview (from thespec import 
  
  EXT_blend_func_separate introduced separate RGB and alpha blend
  factors.  EXT_blend_minmax introduced a distinct blend equation for
  combining source and destination blend terms.  (EXT_blend_subtract &
  EXT_blend_logic_op added other blend equation modes.)  OpenGL 1.4
  integrated both functionalities into the core standard.
  
  While there are separate blend functions for the RGB and alpha blend
  factors, OpenGL 1.4 provides a single blend equation that applies
  to both RGB and alpha portions of blending.
  
  This extension provides a separate blend equation for RGB and alpha
  to match the generality available for blend factors.

The official definition of this extension is available here:
