actually.. when i was at the CDC i saw the source code to this routine
hopefully finding a good implementation for the PilRC rgbtoindex()
routine.. :))
it is a complex routine, and if you are going to call it - do it in
your initialization of the application. then you can keep a 256 byte
array of color indexes in which you can address later very quickly :)
