mediawiki-extensions-Math/modules/MathJax/jax/element/mml/jax.js
Brion Vibber a36b0e04d8 Initial experimental import of MathJax source into Math extension as a client-side rendering supplement to the PNG rendering. 
* Pulled in MathJax 1.1 (minus the 112 megabytes of PNG "fonts")
* Pulled in some of <https://en.wikipedia.org/wiki/User:Nageh/mathJax> bits for initialization

This doesn't currently override PNG images, but does replace the text-form if you configure it.
