OpenGL extension NV.texture_env_combine4
Overview (from the spec)
New texture environment function COMBINE4_NV allows programmable
texture combiner operations, including
ADD Arg0 * Arg1 + Arg2 * Arg3
ADD_SIGNED_EXT Arg0 * Arg1 + Arg2 * Arg3 - 0.5
where Arg0, Arg1, Arg2 and Arg3 are derived from
ZERO the value 0
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
TEXTURE<n>_ARB texture color of the <n>th texture unit
In addition, the result may be scaled by 1.0, 2.0 or 4.0.
