If you're interested I got SVG/PDF export working for the contour plot and
3-D view. However, it results in huge files (1.5Mb for the SVG of the
contour example), and takes 30-minutes to render on my machine ! :-(

I think the latter issue is fixable: looks like a memory thrashing issue in
gl2ps.c, but given the file sizes I can't be bothered to look into right
now... instead I'll wait for Paul to finish off the SVGPlot code and try
and produce contour plots with that.
