Store clipping box coordinates in device units for generic wxDC

Browse source 
Clipping box coordinates should be stored internally in device units
to be independent on changes of logical coordinates made between calls
to wxDCImpl::DoSetClippingRegion().
These stored coordinates should be converted on demand to the current
logical units on call to wxDCImpl::DoGetClippingRect().
