++ Thanks Tor, for your reply. It seems we are discussing
the same issue, so Im sorry to have confused you. Yes -
that would be what I wanted - all according to the same
system - but it simply isn't so with my present installed
version of povray... it is possible I have gotten a broken
code, or otherwise messed with things by mistake.
I will try to put together a small example later...
your answer is suprising to me though... maybe I should just
start using whatever version you do :)
