/**
 * Native bindings to the EXT_texture_snorm extension.
 * 
 * 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.
 * 
 * Requires {@link GL30 OpenGL 3.0}.
