Raw Blame History

/*
* ColorPanel for WINGs
*
* by ]d : Original idea and basic initial code
* Pascal Hofstee : Code for wheeldrawing and calculating
* colors from it.
* Primary coder of this Color Panel.
* Alban Hertroys : Optimizations for algorithms for color-
* wheel. Also custom ColorPalettes and
* magnifying glass. Secondary coder ;)
* Alfredo K. Kojima : For pointing out memory-allocation
* problems and similair code-issues
* Marco van Hylckama-Vlieg : For once again doing the artwork ;-)
*
* small note: Tabstop size = 4
*
*/
/* BUGS:
* For some reason after using the magnifying glass, the windowlist
* of the color-panel (panel->view->screen) becomes 0x0. This
* results in a core-dump of testcolorpanel, and in 3 times
* "WPrefs in free(): warning: chunk is already free." with WPrefs.
*/
/* TODO:
* - Custom color-lists and custom colors in custom colo-lists.
* - Stored colors
* - Resizing
