'''OpenGL extension EXT.texture_env_combine
This module customises the behaviour of the
OpenGL.raw.GL.EXT.texture_env_combine to provide a more
Python-friendly API
Overview (from thespec import
New texture environment function COMBINE_EXT allows programmable
texture combiner operations, including:
REPLACE Arg0
MODULATE Arg0 * Arg1
ADD Arg0 + Arg1
ADD_SIGNED_EXT Arg0 + Arg1 - 0.5
INTERPOLATE_EXT Arg0 * (Arg2) + Arg1 * (1-Arg2)
where Arg0, Arg1 and Arg2 are derived from import
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
and Arg2 is restricted to the alpha component of the corresponding source.
In addition, the result may be scaled by 1.0, 2.0 or 4.0.
