Hi all, Fredrick Brennan on TeX.sx [1] pointed out that SVG plugin for Pstoedit is shareware and it isn't therefore included in distributions. This explains why it didn't work I suppose :)
Anyway, it doesn't make sense to use DVI -> PS -> SVG route anymore, since we have dvisvgm, which is included in all TeX distributions, so I updated tex4ht-env.tex to use it. I added it to both Unix and Windows versions. Another question: does it still make sense to use Dvips and GS for PNG conversion? Shouldn't we use Dvipng by default? It produces much better results.
