I have an old book, _The Elements of Programming Style_, and it says not to use
absolute epsilons.  Never having written a ray tracing program myself (always
on my to-do list since i'd first heard the term, if not before), i don't feel
right telling the POV team what to do.  Not that i could demand my money back
or anything. ;-)
