I'll put it on the list to again review in povr. I'd first noticed it
with povr's, again truly random jitter with and big jitter values (>1).
Maybe I did something which caused the problem while banging on code! Or
maybe the windows version is for some reason different - in official
POV-Ray code, RTR doesn't work on unix/linux machines.
Hmm, I got the compiles set now to turn off the duplicate vector zeroing
on allocation. Maybe the duplicate zeroing was covering some other
behavior as I've found quite a few times already. To test such thoughts
is why there is the povr configure option:
--enable-vector-zeroing enable old, nearly always unneeded vector zeroing.
