It doesn't make much sense to require all the graphics backends to create wxGraphicsPen from either wxPen or wxGraphicsPenInfo when the former can be handled just once in the common code. So do just this, leaving CreatePen() overload taking wxGraphicsPenInfo where the real pen construction takes place and implementing wxGraphicsPen creation from wxPen in the common wxGraphicsContext code. This is not 100% backwards-compatible as any code inheriting from wxGraphicsRenderer and overriding its CreatePen() will now be broken, however this should be extremely rare (there is no good reason to inherit from this class in the user code) and result in compile errors if it does happen.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at http://docs.wxwidgets.org/
