// We could do nothing, because wxWidgets 3 supports the SVG format
// (previously, it was a contribution library, not included in wxWidgets)
// However arcs are drawn as pies, and we must change it.
// Unfortunately most of functions are private, and we cannot derive
// our KicadSVGFileDCImpl from wxSVGFileDCImpl
// and just override the 2 incorrect functions
// Just wxWidget dcsvg is copied here and 2 functions are modified:
// KicadSVGFileDCImpl::DoDrawArc() and KicadSVGFileDCImpl::DoDrawEllipticArc()
// Also note: SetLogicalFunction() does not set an error in debug mode
