Details:

The attached patch is a preliminary implementation of a latex interpreter for
graphics.

The new latex_renderer searches for latex, dvipng and dvisvgm executables on
the path and eventually uses them to render pixels on-screen, or path (not
characters) in SVG and PDF formats.

The process is quite slow, even after caching already parsed strings (see
debug messages appearing each time a new string is parsed), and I don't think
we can do much better without implementing our own latex engine. 

The implementation has to be polished, in particular it uses an ugly global
variable for caching (which is not thread safe among others), but I'd like to
have feedback and eventually advises before proceeding.
