	I quickly tested your script with the current developmental version
of POV-Ray under Linux (compiled with gcc 3.3.1) and obtain the exact same
statistics as your windows binary compiled with icl:


Image Resolution 384 x 216

	and the image looks like that you obtain under windows. On the other
hand, using a custom compile of 3.50c (with a gcc version I don't remember)
gives the same "wrong" image but with different statistics. I can't tell
whether it means gcc is the reason of these discrepancies. But at the end,
it seems that the next version of povray should give consistent results
between platforms  :-)  [well, the last post of ABX seems to pretend the
opposite though...]
