SimpleDragTracker
A tracker for creating new bendpoints or dragging existing ones. The Connection
bendpoint tracker is returned by connection bendpoint handles. This tracker will send a
BendpointRequest to the connection editpart which originated the tracker. The
bendpoint request may be either a request to move an existing bendpoint, or a request
to create a new bendpoint.
A ConnectionBendpointTracker operates on a single connection editpart.
