Handler to draw a point on the map. Point is displayed on mouse down, moves on mouse move, and is finished on mouse up. The handler triggers callbacks for ‘done’, ‘cancel’, and ‘modify’. The modify callback is called with each change in the sketch and will receive the latest point drawn. Create a new instance with the OpenLayers.Handler.Point constructor.
