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