slouken@0
  2054
slouken@0
  2055
   The "best" way to do this is to sort the colors by diversity and place
slouken@0
  2056
   the most diverse colors into the limited palette.  Unfortunately this
slouken@0
  2057
   results in widely varying colors being displayed in the interval during
slouken@0
  2058
   which the windows palette has been set, and the mapping of the shadow
slouken@0
  2059
   surface to the new palette.  This is especially noticeable during fades.
slouken@0
  2060
slouken@0
  2061
   To deal with this problem, we can copy a predetermined portion of the
slouken@0
  2062
   full palette, and use that as the limited palette.  This allows colors
slouken@0
  2063
   to fade smoothly as the remapping is very similar on each palette change.
slouken@0
  2064
   Unfortunately, this breaks applications which partition the palette into
slouken@0
  2065
   distinct and widely varying areas, expecting all colors to be available.
slouken@0

slouken@0
