'''OpenGL extension ARB.texture_env_crossbar
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_env_crossbar to provide a more
Python-friendly API
Overview (from the spec)
This extension adds the capability to use the texture color from
other texture units as sources to the COMBINE_ARB enviornment
function. The ARB_texture_env_combine extension defined texture
enviornment functions which could use the color from the
current texture unit as a source. This extension adds
the ability to use the color from any texture unit as a source.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/texture_env_crossbar.txt
