With that in mind, I think it would be good to have SVG images of other piece sets.
I also found SVGs in the XBoard themes collection for the orthodox pieces in Motif. The unorthodox Magnetic pieces seem to be mostly cut & paste jobs of the orthodox pieces, and should be easy to create that way from the orthodox SVG. I will have a go at it.
[Edit] OK, this is done. The original Magnetic set actually has two kind of pieces: outline and solid. As is usual for XBoard with its native pieces too, the solid pieces are used for black there. But it seems we only use the outline pieces on CVP, and just color those differently depending on whether they are used for white or black. So I did not bother to create unorthodox solid piece.
The entire set is now in /graphics.dir/magneticSVG.
[Edit 2] I now also did Motif. They are in /graphics.dir/motifSVG.
