support for rendering latex equations

[martinjrobins]

I would really like to be able to add latex equations for axis labels, but this seems like it would be very difficult to achieve in pure C++. There seems to be no C++ parsers or renderers for latex. Any ideas for how to do this?

Here is a java library for latex: https://github.com/opencollab/jlatexmath
Here is a "C++" library for latex that laughably just generates javascript (!) and use KaTex to render the equations (perhaps their parser is in C++, I didn't check): https://github.com/goldsborough/latexpp

might be able to include mathml as a foreignObject in svg, see https://stackoverflow.com/questions/27840705/rendering-mathml-on-svg-using-d3-js

Well... it would be nice to have it completely within svg, if at all possible. How about:

1. Work out how to go TeX -> svg (e.g. this)
2. Embed the resulting svg in the output

[martinjrobins]

yea, agreed. Here are a few libraries to compile the TeX:
