Place flattened every top-level layer into its objects, so an SVG's clipped top-level group lost
its clip and its clipping path came in as a loose, invisible path; sublayers lost their clips the
same way. A clipping layer is now placed as one clip group, for SVG/DXF and for the art placed from
an artboard (PDF, EPS, placed documents) alike.
