'''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 thespec import 
  
  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  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
  
  This operaion can only be performed if SOURCE0_RGB_EXT,
  SOURCE1_RGB_EXT are defined.
