OpenGL extension EXT.light_texture
This module customises the behaviour of the
OpenGL.raw.GL.EXT.light_texture to provide a more
Python-friendly API
Overview (from the spec)
This extension defines a general mechanism for substituting the
fragment color computed during texture environment processing in
place of other fragment attributes such as the fragment normal, or
as sources for some of the computations in the fragment processing
pipeline, for example as material or light parameters in the
fragment lighting computations.
