 /**
 * @class Roo.dd.DDTarget
 * A DragDrop implementation that does not move, but can be a drop
 * target.  You would get the same result by simply omitting implementation
 * for the event callbacks, but this way we reduce the processing cost of the
 * event listener and the callbacks.
 * @extends Roo.dd.DragDrop
 * @constructor
 * @param {String} id the id of the element that is a drop target
 * @param {String} sGroup the group of related DragDrop objects
 * @param {object} config an object containing configurable attributes
 *                 Valid properties for DDTarget in addition to those in
 *                 DragDrop:
 *                    none
