  Log:
  Another fix based on venomgfx fraka .blend:
  
  In december, when testing material layering, I've removed the check that
  prevented specular and diffuse to become negative, this because it could
  work nice for layering.
  
  However, this breaks quite some cases too. For example negative lamps are
  only used to cancel out other lights in same material, and should not give
  negative (invisible!) peaks that work on a node system. Same goes for
  negative diffuse from AO 'subtract' mode.
  
  In fraka the error happened for AO on a translucent material. The inside
  of the mesh got a negative AO, cancelling out the positive AO on the
  outside.
  
  Anyhoo; this commits ensures that a 'shade_lamp_loop' call will never
  return negative values again!
