and thus removed all the duplicated code in all wxDC
classes.
Problematic is that wxSVGFileDC and wxPostscriptDC inherit
from wxDC and therefore include platform specific code
(also before this change) so I chose to override all
SetLogicalOrigin() etc. methods in these classes and
call their wxDCBase methods thereby circumventing the
platform dependent code.
I'm afraid the Mac code will require updating, too.
