The Handles of a viewer should be determined via the findHandleAt(Point) method declared by the GraphicalViewer interface. This interface needs to be implemented by our GraphicalViewer, just like the Handle interface needs to be implemented by our Handle. The drag-tracker tool getter and setter have to be renamed to match the signature specified by the interface.
