'''OpenGL extension ARB.texture_env_add
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_env_add to provide a more
Python-friendly API
Overview (from the spec)
New texture environment function ADD is supported with the following
equation:
Cv = min(1, Cf + Ct)
New function may be specified by calling TexEnv with ADD token.
One possible application is to add a specular highlight texture to
a Gouraud-shaded primitive to emulate Phong shading, in a single
pass.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/texture_env_add.txt
