If you look at the date of the first message (2002), I believe there
might be a problem of licensing:
 * there is no explicit license in the first message
 * at that time, the license of povray was different from the current
AGPL (if I got that right)
 * cannot contact the original poster to clarify

(and to make matter more complex: Poland might not recognize IP about
trivial algorithm but some bigger confederations on other continent
might: so the lack of explicit license might not be a problem in Poland,
but the usage as such in a state of U.S.A. might violate (or not) one or
more patents...)
