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. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@45752 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
