OpenGL.GL.EXT.shader_integer_mix
OpenGL extension EXT.shader_integer_mix
This module customises the behaviour of the
OpenGL.raw.GL.EXT.shader_integer_mix to provide a more
Python-friendly API
Overview (from the spec)
GLSL 1.30 (and GLSL ES 3.00) expanded the mix() built-in function to
operate on a boolean third argument that does not interpolate but
selects. This extension extends mix() to select between int, uint,
and bool components.
The official definition of this extension is available here:
