    svg: write Dia's only fill-rule used
    
    Still ignored on load in dia_svg_parse_style*() and svg-import.
    Implementing fill-rule="nonzero" would either require an extension
    to the renderer interface and the poly and bezier objects or at
    least some more post-processing after dia_svg_parse_path().
