AddDropHandler
Allow override of the default behavior for the corresponding window. Multiple handlers can be registered on the same window. If a handler returns DragAndDropVisualMode.None the system will check the next handler. Any other results ( DragAndDropVisualMode.Rejected or others DragAndDropVisualMode ) means this handler has processed the drop event and no other handler will be called. The last handler is the default Unity handler.
