Err, not entirely true Dave. According to Alan, Lightwave actually renders
color at 96bits per pixel (32 bits per gun -- red green and blue) and dithers
down to 24 bit.
Apparently when going to some output devices, 8 bits per channel is too fine
a resolution. Has anyone seen a filter of sorts that could redither to lower
bits per pixel without creating CLUTs? Sort of a quantize & dither without
the histogram/palette steps.
