i realize that there is an refrenence to this in the
frequently asked question. the algorithm there is crummy. pbmplus if
loaded with bugs, and its quantization algorithm doesn't work well if
the color resolution is lowered a lot (i.e. going from 8 bits per primary
to 2 bits per primary). also it doesn't do the first pixel of every other 
line, does something strange at the end of everyother line, and it
the arithmatic overflows in several places if i use 16bit ints, 32bit longs.
i want a diferent algorithm: one that handles lowering of color resolution
and limiting of the palette better.
