I'm looking for information on how to quickly generate an inverse
palette (see Inside Mac V-137 for a discussion of inverse palettes).
Using the brute force method, with lots of optimization and common
sub-expression work, the best I've been able to do is 1.5 minutes on an
8 MhZ 286 (this is for a 15 bit (5x5x5) inverse palette); which is way
slower than the Mac toolbox can do it. Therefore I'm assuming there's
a better algorithm (I've thought about "growing" the inverse palette,
similar to a seed fill, but I can't see how this will be any faster
(and it would certainly require lots of memory)).
I've already looked at PBMPLUS, it doesn't build an inverse palette.
