Before anyone else corrects me - maybe they already have:
The palettes in 3200 mode are stored like this:
Palette for scanline 0: Color F, E, D, ...., 0
.
.
Palette for scanline 199: Color F, E, ......, 0
I guess I have not had enough sleep.

Should the standard store them like this just because all existing formats do?
A thought I had is that within APF the colors should be sorted (for each
scanline) such that the lightest colors appear first in the palette.
This would mean that a single grey scale palette would be effective for the
entire picture (and could be stored in the main chunk).
Of course if the picture had horizontal bands of darkness - ie: it was much
darker at the top than the bottom for example - you would get distortion -
but many pictures could be made sense of in this manner.
