  If this is so, then it means that there's actually just one single
fixed stream of pseudo-random numbers in POV-Ray, and with seed() you
just tell where to start taking numbers from this stream.
  (On implication of this is that if you have two streams generated
with different seed() values, they will both eventually start to give
the same numbers as the other.)
