* A color well is a widget which controls color settings.
* Colors may be dragged and dropped from one color well to another,
* or from color wells to other widgets that understand standard drag-and-drop
* behavior, like for example the Gradient Bar widget.
* A double-click inside a color well will bring up the standard
* color dialog panel to edit the color well's color.
* While the color value is being changed, the color well sends a SEL_CHANGED
* to its target; at the end of the change, it sends a SEL_COMMAND.
* The message data represents the current color value, of the type FXColor.
