  * Laden des Containers.
  * reset distortion funktioniert.
- * statesetmanipulator muss auf die scene, nicht auf mesh losgehen.
- * 
  * Anwenden der distortion auf die Meshknoten oder die texturekoordinaten

+ * oder alternativ: 
  * - speichern der hieght und width im container so daß das mesh an andere Bildschirmgrößen angepasst werden kann.
