|*
|*	Ersterstellung:		KA 24.11.95
|*	letzte Aenderung:	KA 24.11.95
|*
|*	Zeck:	dient beim MetaFile-Export dazu, die eigentliche Berechungs-
|* 			funktionalitaet zu kapseln. Das Schreiben der Records fuer
|*			die unterschiedlichen File-Formate geschieht ueber LinkHandler.
|*
|*			Klassen, die diesen Wrapper benutzen, muessen drei Linkhandler
|* 			zur Verfuegung stellen, die im Ctor uebergeben werden:
|*
|*				1. Linkhandler zum Schreiben eines Records fuer Polygonausgabe
|*				2. Linkhandler zum Schreiben eines Records fuer PolyPolygonausgabe
|*				3. Linkhandler zum Schreiben eines Records fuer Setzen der Brush
