|*  class GradientWrapper
|*
|*  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
