Todo:
- Make a new Module "GLMappers" and move everything related there and declare it deprecated
- Add dependency to "GLMappers" for Modules like PlanarFigures, ContourModul, MapperExt, Segmentation etc. (todo MBI)
- Create new VtkMapper replacements for:
-SurfaceGLMapper2D
-PlaneGeometryDataMapper2D
- Remove the OpenGL Hacks from the VtkPropRenderer.
- Party! (and Docu)
