'''OpenGL extension EXT.texture_env_dot3
This module customises the behaviour of the
OpenGL.raw.GL.EXT.texture_env_dot3 to provide a more
Python-friendly API
Overview (from the spec)
Adds new operation to the texture combiner operations.
DOT3_RGB_EXT Arg0 <dotprod> Arg1
DOT3_RGBA_EXT Arg0 <dotprod> Arg1
where Arg0, Arg1 are derived from
PRIMARY_COLOR_EXT primary color of incoming fragment
TEXTURE texture color of corresponding texture unit
CONSTANT_EXT texture environment constant color
PREVIOUS_EXT result of previous texture environment; on
texture unit 0, this maps to PRIMARY_COLOR_EXT
This operaion can only be performed if SOURCE0_RGB_EXT,
SOURCE1_RGB_EXT are defined.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/texture_env_dot3.txt
