2169 | results in widely varying colors being displayed in the interval during |
2170 | which the windows palette has been set, and the mapping of the shadow |

2172 | |
2173 | To deal with this problem, we can copy a predetermined portion of the |
2174 | full palette, and use that as the limited palette. This allows colors |
2175 | to fade smoothly as the remapping is very similar on each palette change. |
2176 | Unfortunately, this breaks applications which partition the palette into |
2177 | distinct and widely varying areas, expecting all colors to be available. |
