mathjax and fragments

[haraldschilly]

If anyone is also struggling with wrongly rendered formulas after they are revealed via fragments, try adding this at the bottom of the page:

<script>
Reveal.addEventListener( 'fragmentshown', function( event ) {
setTimeout(
   function() {
     MathJax.Hub.Rerender(document.querySelector(".slides .present"))
   }, 100); 
} );
</script>

This could be added to the Readme or the Wiki …
