Dragging a marker v2.46+
An option to make markers draggable was given to us with v2.46. There are three markers on the map. One of them

Point of the dragged marker is returned by .getPoint() method and updated by 'drag' event available from a
draggable marker.
Do not confuse mouse pointer point with that:
