2 * ColorPanel for WINGs
3 *
4 * by ]d : Original idea and basic initial code
5 * Pascal Hofstee : Code for wheeldrawing and calculating
6 * colors from it.
7 * Primary coder of this Color Panel.
8 * Alban Hertroys : Optimizations for algorithms for color-
9 * wheel. Also custom ColorPalettes and
10 * magnifying glass. Secondary coder ;)
11 * Alfredo K. Kojima : For pointing out memory-allocation
12 * problems and similair code-issues
13 * Marco van Hylckama-Vlieg : For once again doing the artwork ;-)

18 /* TODO:
19 * - Look at further optimization of colorWheel matrix calculation.
20 * It appears to be rather symmetric in angles of 60 degrees,
21 * while it is optimized in angles of 90 degrees.
22 * - Custom color-lists and custom colors in custom color-lists.
23 * - Stored colors
24 * - Resizing
