* 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
*
