How about PNGs algorithm?  I'm not suggesting the interleaving stuff; but I
thought the spatial filtering bits were important in order to get the best
out of the subsequent ZIP style compression.

I'm fed up with not having a decent free lossless compression algorithm
available for TIFF, too.  Is there some way this group can move things
along?
