1 please don't forget to update Makefile_insert files - I did this for the moved n-art-bpath-2geom.cpp/h

2 even then, linking fails:

libnr/libnr.a(n-art-bpath-2geom.o): In function `SVGEllipticalArc':./2geom/path.h:287: undefined reference to `vtable for Geom::SVGEllipticalArc' libnr/libnr.a(n-art-bpath-2geom.o): In function `Geom::SVGPathGenerator<std::back_insert_iterator<std::vector<Geom::Path, std::allocatorGeom::Path > > >::arcTo(double, double, double, bool, bool, Geom::Point)':./2geom/path.h:297: undefined reference to `Geom::SVGEllipticalArc::calculate_center_and_extreme_angles()' collect2: ld returned 1 exit status

please fix asap
