[Octave-bug-tracker] [bug #59546] Missing latex interpreter

[Pantxo Diribarne]

Follow-up Comment #44, bug #59546 (project octave):

I finally pushed the patch after adding some documentation:

http://hg.savannah.gnu.org/hgweb/octave/rev/2ae4764180c6

Apart from the already known issue with the cache, I just noticed another
problem: the QSvgRenderer renders text as path, which means not only LaTeX
strings but also normal ones loose textual font info.
This is a regression and it looks like using QSvgRenderer was a bad option
since there is not much you can do to control what it does in the background.

I have a fix that consists in reverting most of the changes and adding support
for path elements in our hand-rolled svg renderer. For this the simplest way
was to borrow some chunks of code in Qt's source code. Is it OK to do so?
