2023 by windows. | |
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. | |
