Use dvisvgm to preview latex fragments

Use dvisvgm to preview latex fragments

I find a new tool: dvisvgm (https://github.com/mgieseki/dvisvgm)  ,which we can use it to preview latex fregments, it can deal with
xetex's xdv file as well (it will available in texlive2016).

The questions are:
1.  which path we should use:   "dvi/xdv -> svg" or "dvi/xdv -> svg -> png" ?
2. if we use the first path, how to deal with org-latex-preview-ltxpng-directory?  should we rename it to org-latex-preview-ltximg-directory or
   org-latex-preview-ltxpic-directory ?

That looks very cool.  Thanks for the pointer!

Will you be working on a patch for supporting dvisvg?

Depends on which format Emacs supports.  If it’s compiled with svg support
I’d guess it’s better since it’s vector graph and potentially could scale
nicer when increasing font size.  But I don’t know how easy it would be to
incorporate inlined svg display.  At the very minimum you will have to
look at e.g. org-create-formula-image and "surrounding" functions, which
will bark at "dvisvg" ATM.

It might also be nice to make it possible to incorporate svg images for
math in odt where formula support is a bit lackluster.

If you provide a patch that enables svg support you can change the default
value.
