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