/** 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.
@author OD
@param _pOrgOutDev
input parameter - constant instance of the original output device, for which
the virtual output device is created.
@param _pVirDev

@param _pMapMode
input/output parameter - instance of the mapping mode, which will be set
at the virtual output device.
@param _rNewOrigin
input parameter - constant instance of the origin, which will be used in
