| 2024 | |
| 2025 The "best" way to do this is to sort the colors by diversity and place | |
| 2026 the most diverse colors into the limited palette. Unfortunately this | |
| 2027 results in widely varying colors being displayed in the interval during | |
| 2028 which the windows palette has been set, and the mapping of the shadow | |
| 2029 surface to the new palette. This is especially noticeable during fades. | |
| 2030 | |
| 2031 To deal with this problem, we can copy a predetermined portion of the | |
| 2032 full palette, and use that as the limited palette. This allows colors | |
| 2033 to fade smoothly as the remapping is very similar on each palette change. | |
| 2034 Unfortunately, this breaks applications which partition the palette into | |
| 2035 distinct and widely varying areas, expecting all colors to be available. | |
| 2036 | |
| 2037 I'm making them both available, chosen at compile time. | |
