No transaction is performed by this tool, although it is possible (but unconventional) that DoRubberBand might be overridden to perform one. This tool is normally used as a modeless tool, one of the view's mouse tools, that can be started upon a mouse move (GoView.MouseMoveTools). When the Modal property is set to true, this tool waits for a mouse down at which CanStart returns true before drawing the rubber-band box.
