  Uses modules: dtCore, dtABC, dtUtil
  
  Purpose
  -------
  To provide an example of how to do dot3 normal mapping
  with GLSL.
  
  Definition
  ----------
  A normal map provides the per-pixel normals in texture by 
  storing vectors instead of colors, so RGB is really (X,Y,Z).
  The normals define the pertubations of the surface.  Since the
  normals are relative to the surface they are on, the light vector
  must be transformed to this space (tangent space) before doing the 
  lighting calculation.  
  
  Controls
  --------
  Space - Toggle the geometry that is rendered
  Esc   - Exit
  '1'   - Render lit with bump
  '2'   - Render base texture
  '3'   - Render the normal texture
  '4'   - Render the diffuse color
  '5'   - Render the specular color
  '6'   - Render the full lighting contribution
  
  Orbit Motion Model:
  Left  Mouse Button  - Look up/down, turn left/right
  Middle Mouse Button - Move closer/farther
  Right Mouse Button  - Move forward/backward
