In current versions MapMode handling is done in ::TRSet/Get-
BaseGeometry methods. These belong to SdrModel level and
should not do any MapMode conversions (else all geometry
and Rectangle setters/getters should have to do these, too).
Instead, the UNO API implementation should do these, there
are already some done there and this is the level which offers
pure 100ThMM handling to the caller, independent from the
used application.
