Fascinating! You're explanation is clear and concise (although I have to admit
that some of this code stuff is a bit beyond me.) Nevertheless, I'm
learning...thanks to your well-written responses.  (I nominate *you* to
re-write the POV documentation! Shouldn't take you long...heh heh...)

Hmm, well --*gulp*--I guess I'm going to have to bite that bullet. Thanks for
the confidence boost. (My trepidation basically comes from the idea that I'll
get bogged down in its not-yet-working details--"Why doesn't this work?" "What
am I doing wrong?" etc.--and get completely frazzled, when even good ol' 3.6.1c
keeps me 'busy' in that regard. But I guess that the POV team *needs* beta
testers to find out such stuff, for the good of us all.)

Great! And thanks for being so thorough. BTW, those are some impressive time
statistics. I'm still using a 'lowly' 2.2GHZ AMD single-core system. Perhaps
it's time to do the upgrade thing (again, *sigh*.)
