>   class   SGFontsDragTarget : public SGListDragTarget

    Author:     Will_Cowling (Xara Group Ltd) <camelotdev@xara.com>
    Created:    8/4/95

    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 BitmapSGalllery items
                within their displayed list. It automatically handles drags with draginfo
                derived from BitmapDragInformation.

    Notes:      Drag targets are destructed automatically when a drag finishes by the drag
                manager with which they were registered.

                To remove a drag target at any time, destruct it - it automatically deregisters
                and cleans up.
