  Wouldn't this kind of optimization mean that POV-Ray would have to keep
all the intersections of a ray and the scene in memory?
  Does it do that already? If yes, I don't understand why. POV-Ray only
uses the closest intersection so why would it need to keep in memory
all the intersections?
  If no, then how would this kind of optimization affect memory consumption
and speed? After all, a ray can intersect the scene in thousand and
thousands of places...
