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