       *
       * This extension provides for the addition of markers to the either end
       * or the middle of a line, polyline, path, polygon.
       *
       * Markers may be either a graphic or arbitary text
       *
       * to simplify the coding and make the implementation as robust as possible,
       * markers are not shared - every object has its own set of markers.
       * this relationship is maintained by a naming convention between the
       * ids of the markers and the ids of the object
       *
       * The following restrictions exist for simplicty of use and programming
       *    objects and their markers to have the same color
       *    marker size is fixed
       *    text marker font, size, and attributes are fixed
       *    an application specific attribute - se_type - is added to each marker element
       *        to store the type of marker
       *
       * @todo
       *    remove some of the restrictions above
       *    add option for keeping text aligned to horizontal
       *    add support for dimension extension lines
