'''OpenGL extension EXT.texture_snorm
This module customises the behaviour of the
OpenGL.raw.GL.EXT.texture_snorm to provide a more
Python-friendly API
Overview (from the spec)
Fixed-point textures in unextended OpenGL have integer components,
but those values are taken to represent floating-point values in
the range [0.0,1.0]. These integer components are considered
"unsigned normalized" integers. When such a texture is accessed by
a shader or by fixed-function fragment processing, floating-point
values are returned in the range [0.0,1.0].
This extension provides a set of new "signed normalized" integer
texture formats. These are taken to represent a floating-point
value in the range [-1.0,1.0] with an exact 0.0.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/texture_snorm.txt
