[tex4ht] problem with new dvisvgm 2.6, all svg fies have horizontal lines with no math showing.

[Martin Gieseking]

Hi Nasser,

I just had a quick look at your files. None of your SVG files contain 
the required font/path data so that they can't be rendered correctly. 
Since I can't reproduce the issue here, your dvisvgm binary is probably 
broken. For example, if you linked against the wrong kpathsea library, 
the font files can't be found, which would explain the results. This 
happens if you installed the original TL (with tlmgr) but link dvisvgm 
against libkpathsea coming with Ubuntu that usually belongs to a 
different TL version and searches in a different directory tree.

TL doesn't provide packages of the header and static library files, so 
that the only possibility is probably to download the TL sources, update 
the dvisvgm code there and rebuild it.
