slouken@0
  2014
slouken@0
  2015
   The "best" way to do this is to sort the colors by diversity and place
slouken@0
  2016
   the most diverse colors into the limited palette.  Unfortunately this
slouken@0
  2017
   results in widely varying colors being displayed in the interval during
slouken@0
  2018
   which the windows palette has been set, and the mapping of the shadow
slouken@0
  2019
   surface to the new palette.  This is especially noticeable during fades.
slouken@0
  2020
slouken@0
  2021
   To deal with this problem, we can copy a predetermined portion of the
slouken@0
  2022
   full palette, and use that as the limited palette.  This allows colors
slouken@0
  2023
   to fade smoothly as the remapping is very similar on each palette change.
slouken@0
  2024
   Unfortunately, this breaks applications which partition the palette into
slouken@0
  2025
   distinct and widely varying areas, expecting all colors to be available.
slouken@0
  2026
slouken@0
