'''OpenGL extension ATI.texture_mirror_once
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://oss.sgi.com/projects/ogl-sample/registry/ATI/texture_mirror_once.txt
