'''OpenGL extension EXT.texture_perturb_normal
This module customises the behaviour of the
OpenGL.raw.GL.EXT.texture_perturb_normal to provide a more
Python-friendly API
Overview (from the spec)
This extension defines a mechanism for using texture values to perturb
the fragment normal vector prior to fragment lighting. It enables a
direct implementation of the original formulation of bump mapping by
Blinn.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/texture_perturb_normal.txt
