34 |*	Ersterstellung:		KA 24.11.95
35 |*	letzte Aenderung:	KA 24.11.95
36 |*
37 |*	Zeck:	dient beim MetaFile-Export dazu, die eigentliche Berechungs-
38 |* 			funktionalitaet zu kapseln. Das Schreiben der Records fuer
39 |*			die unterschiedlichen File-Formate geschieht ueber LinkHandler.
40 |*
41 |*			Klassen, die diesen Wrapper benutzen, muessen drei Linkhandler
42 |* 			zur Verfuegung stellen, die im Ctor uebergeben werden:
43 |*
44 |*				1. Linkhandler zum Schreiben eines Records fuer Polygonausgabe
45 |*				2. Linkhandler zum Schreiben eines Records fuer PolyPolygonausgabe
46 |*				3. Linkhandler zum Schreiben eines Records fuer Setzen der Brush
