Using wxSVGFileDC in locales using comma as decimal separator resulted in invalid SVG files being created as a decimal period should always be used in them. Fix this by replacing "%g" format specification with wxString::FromCDouble() call (wrapped in a convenient NumStr() helper function). Closes #12008. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@67188 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
