'''OpenGL extension ATI.texture_mirror_once

This module customises the behaviour of the 
OpenGL.raw.GL.ATI.texture_mirror_once to provide a more 
Python-friendly API

Overview (from the spec)
	
	ATI_texture_mirror_once extends the set of texture wrap modes to 
	include two modes (GL_MIRROR_CLAMP_ATI, GL_MIRROR_CLAMP_TO_EDGE_ATI) 
	that effectively use a texture map twice as large as the original image 
	in which the additional half of the new image is a mirror image of the 
	original image.
	
	This new mode relaxes the need to generate images whose opposite edges
	match by using the original image to generate a matching "mirror image".
	This mode allows the texture to be mirrored only once in the negative
	s, t, and r directions.

The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ATI/texture_mirror_once.txt
