slouken@0
  1984
slouken@0
  1985
   The "best" way to do this is to sort the colors by diversity and place
slouken@0
  1986
   the most diverse colors into the limited palette.  Unfortunately this
slouken@0
  1987
   results in widely varying colors being displayed in the interval during
slouken@0
  1988
   which the windows palette has been set, and the mapping of the shadow
slouken@0
  1989
   surface to the new palette.  This is especially noticeable during fades.
slouken@0
  1990
slouken@0
  1991
   To deal with this problem, we can copy a predetermined portion of the
slouken@0
  1992
   full palette, and use that as the limited palette.  This allows colors
slouken@0
  1993
   to fade smoothly as the remapping is very similar on each palette change.
slouken@0
  1994
   Unfortunately, this breaks applications which partition the palette into
slouken@0
  1995
   distinct and widely varying areas, expecting all colors to be available.
slouken@0
  1996
slouken@0

   I'm making them both available, chosen at compile time.
