OpenGL.GL.EXT.blend_equation_separate

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 the spec)

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.
