31 /** method to set mapping/pixel offset for virtual output device
32 
33     OD 12.11.2002 #96272# - method implements two solutions for the mapping of
34     the virtual output device:
35     The old solution set the origin of the mapping mode, which will be used in
36     the virtual output device. This causes several paint errors, because of the
37     different roundings in the virtual output device and the original output device.
38     The new solution avoids the rounding differences between virtual and original
39     output device by setting a pixel offset at the virtual output device.
40     A local boolean controls, which solution is used, in order to switch in
41     escalation back to old solution.
