Just to follow up: I did try experimenting with some of my own
multispectral images in true color mode. After I displayed the images in
the RGB channels, I then displayed a pure white box in one corner. I
then tried various switches in COLOR_QUAN (e.g. DITHER on and off), but
the 'white' color table entries always came out at 248 rather than 255.
Hence the hack.
Cheers,
Liam.
