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:
