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.
