-/* Compress a full palette into the limited number of colors given to us

-
- The "best" way to do this is to sort the colors by diversity and place
- the most diverse colors into the limited palette. Unfortunately this
- results in widely varying colors being displayed in the interval during
- which the windows palette has been set, and the mapping of the shadow
- surface to the new palette. This is especially noticeable during fades.
-
- To deal with this problem, we can copy a predetermined portion of the
- full palette, and use that as the limited palette. This allows colors
- to fade smoothly as the remapping is very similar on each palette change.
- Unfortunately, this breaks applications which partition the palette into
- distinct and widely varying areas, expecting all colors to be available.
-
- I'm making them both available, chosen at compile time.
- If you want the chunk-o-palette algorithm, define SIMPLE_COMPRESSION,
- otherwise the sort-by-diversity algorithm will be used.
