'''OpenGL extension NVX.blend_equation_advanced_multi_draw_buffers | |
This module customises the behaviour of the | |
OpenGL.raw.GL.NVX.blend_equation_advanced_multi_draw_buffers to provide a more | |
Python-friendly API | |
Overview (from the spec) | |
This extension adds support for using advanced blend equations | |
introduced with NV_blend_equation_advanced (and standardized | |
by KHR_blend_equation_advanced) in conjunction with multiple | |
draw buffers. The NV_blend_equation_advanced extension supports | |
advanced blending equations only when rending to a single color | |
buffer using fragment color zero and throws and INVALID_OPERATION | |
error when multiple draw buffers are used. This extension removes | |
this restriction. | |
The official definition of this extension is available here: | |
http://www.opengl.org/registry/specs/NVX/blend_equation_advanced_multi_draw_buffers.txt | |
