In the tutorial steps using volume rendering (for binary images), volume rendering does not work any longe.

The tutorials still use the old VTK software volume mapper. Using the new GPU volume mapper, everything seems to work correctly.

The old volume mapper still works in the MITK sandbox application (tested by manually disabling GPU volume mapper).

Possible solutions:

a) Fix the problem with the old volume mapper
b) Use new GPU volume mapper in tutorial steps
