Using namespace prefix sodipodi:cx,sodipodi:cy,sodipodi:rx and sodipodi:ry without namespace declaration 'xlmns:sodipodi' makes it difficult to read svg with Ubuntu 20.04 and with later versions
leads to following error : gi.repository.GLib.Error: rsvg-error-quark: XML parse error: error code=201 (3) in (null):31:50: Namespace prefix sodipodi for ry on circle is not defined (0)

Fix by adding namespace declaration 'xlmns:sodipodi'
