- * Adjust an 'indirect' color palette for the color cycling performed on its master
- * palette. An indirect palette is a palette which contains indices pointing into
- * another palette - it provides a level of indirection to map palette colors to
- * other colors. Now when the target palette is cycled, the indirect palette suddenly
- * point at the wrong color(s). This function takes care of adjusting an indirect
- * palette by searching through it and replacing all indices that are in the
- * cycle range by the new (cycled) index.
