91 
92     OD 12.11.2002 #96272# - method implements two solutions for the mapping of
93     the virtual output device:
94     The old solution set the origin of the mapping mode, which will be used in
95     the virtual output device. This causes several paint errors, because of the
96     different roundings in the virtual output device and the original output device.
97     The new solution avoids the rounding differences between virtual and original
98     output device by setting a pixel offset at the virtual output device.
99     A define controls, which solution is used, in order to switch in escalation
100     back to old solution.
