'''OpenGL extension EXT.visual_rating
This module customises the behaviour of the
OpenGL.raw.GLX.EXT.visual_rating to provide a more
Python-friendly API
Overview (from the spec)
This extension allows servers to identify a particular GLX visual as
undesirable. A new visual attribute is introduced, providing a way
for servers to specify caveats (e.g., slow) for a visual. The attribute
may be queried using glXGetConfig, and can therefore be used by
application-specific visual selection routines. The new attribute is
also used by glXChooseVisual to discriminate against visuals with
caveats.
This extension allows servers to export visuals with improved features
or image quality, but lower performance or greater system burden,
without having to have these visuals selected preferentially. It is
intended to insure that most applications get the "right" visual, not
that all applications do.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/visual_rating.txt
