BluffTitler EPS extensions

The sketch layer of BluffTitler uses the EPS format to import line drawings. The EPS format however is limited to 2D positions. BluffTitler adds a few extensions to make 3D positions possible to store, for example, roller coaster paths. Those extensions are introduced at the release of BluffTitler 7.5. They are BluffTitler specific and not compatible with any other software supporting the EPS format.
