/** Handles {@link ColorPicker} actors. Works like any other table: can append any extra children, converts plain text
 * to labels. Is attached to its parent with a specialized click listener, which will show the dialog each time the
 * widget is not disabled and clicked. Note that, as opposed to colorPicker attribute, a new instance of ColorPicker is
 * created for each tag and you HAVE to manage the instance yourself. {@link ColorPicker#dispose()} has to be eventually
 * called in your code. This tag should be used if you plan to use only a few color pickers and need them fully
 * customized; usually simple colorPicker attribute is more than enough. Mapped to "colorPicker".
