  Log:
  Unified renderer OSA sample clipping:
  
  User info:
  	This change limits the contribution of any OSA sample to 1.0 per color
  	in the Unified renderer.  Because color=1.0 gives fully saturated color,
  	samples contributing more than 1.0 were overweighted in the OSA average
  	causing aliasing (sometimes quite severe).
  
  	Samples can contribute more than 1.0 because a material's spec and refl
  	values are not normalized (In real world spec+refl <= 1.0).  This solves
  	a large class of aliasing problems in the unified renderer.
  
  Coder Info:
  	None.
