1982 /* Compress a full palette into the limited number of colors given to us | |
1983 by windows. | |
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 | |
1997 I'm making them both available, chosen at compile time. | |
1998 If you want the chunk-o-palette algorithm, define SIMPLE_COMPRESSION, | |
1999 otherwise the sort-by-diversity algorithm will be used. | |
