    Created:    10/4/95
    Purpose:    An instantiation of this class is created by each entity which wishes to 
                provide a 'destination' to which the mouse can go to complete a drag.
                This particular target is used for handling drags of NameGalllery items
                within their displayed list. It automatically handles drags with draginfo
                derived from BitmapDragInformation.
    Notes:      Drag targets are destroyed automatically when a drag finishes by the drag
                manager with which they were registered.
                To remove a drag target at any time, destroy it - it automatically deregisters
                and cleans up.
