virtual and implement them like any other method
in the wxDC classes, not only in the their files
but somehow belonging to the wxDCBase class.
This is required for plugging in differnt DC backends
with different conversions.
Ideally (and absolutely possible ) all these methods
should be removed and just the one in wxDCBase
should stay using values set in the various
derived classes.
