  44 |*      Zeck:   dient beim MetaFile-Export dazu, die eigentliche Berechungs-
  45 |*                      funktionalitaet zu kapseln. Das Schreiben der Records fuer
  46 |*                      die unterschiedlichen File-Formate geschieht ueber LinkHandler.
  47 |*
  48 |*                      Klassen, die diesen Wrapper benutzen, muessen drei Linkhandler
  49 |*                      zur Verfuegung stellen, die im Ctor uebergeben werden:
  50 |*
  51 |*                              1. Linkhandler zum Schreiben eines Records fuer Polygonausgabe
  52 |*                              2. Linkhandler zum Schreiben eines Records fuer PolyPolygonausgabe
  53 |*                              3. Linkhandler zum Schreiben eines Records fuer Setzen der Brush
