*
* MathJax/extensions/HTML-CSS/handle-floats.js
*
* This extension allows HTML-CSS output to deal with floating elements
* better. In particular, when there are tags or equation numbers, these
* would overlap floating elements, but with this extension, the width of
* the line should properly correspond to the amount of space remaining.
*
* To load it, include
*
* "HTML-CSS": {
* extensions: ["handle-floats.js"]
* }
*
* in your configuration.
