AA screws starfields up because it takes several samples per pixels
and averages them to get the final pixel color, whereas only one or
two of these sample rays will hit a "star" (either texture or object).
So at +r3 stars usuallly get 1/9 or 2/9 or max 1/3 of their intended
brightness. The solution is to color the stars using a high value of
white like White*4.5, for example.
