Support LaTeX typesetting

[gauffke]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I need to include mathematical notations.
Importing equations as images is cumbersome and does not allow to mix text and equations.

Describe the solution you'd like
I'd like to support LaTeX typesetting, to properly render, for example:
Point A coordinates are noted $(x_A;y_A)$
or
Dividing $x$ by $y$ is noted $\frac{x}{y}$

Describe alternatives you've considered
I've tried including code as Javascript, HTML, iframe, ... without success.

Thank you!
