Comment 10 for bug 167579

I'm the one who reported the problem into debian bugzilla.

here's the diff for eqtexsvg.py, which
a) uses better (still silly) svg parsing technique
b) does better tmp file creation
c) uses plot-svg pstoedit driver to produce svgs
d) does not use -output-dir with latex, but the solution is
*nix only =(
