/* CONSIDER: As we scroll the page, light up the "current" section in the TOC.
*
* FIXED: One occasional problem with the TOC is when it is taller than the
* window! (I usually work around this by zooming out (reducing font
* size), but perhaps we can use CSS overflow to solve it properly.)
*
* NOTE: The sidebar toggle now animates smoothly. This is caused by animation
* rules in Wikipedia's CSS. I don't know why they are there, I haven't seen
* anything that makes use of them, except by circumstance, this script!
*
* TODO: Indentation was not working well in edit preview on Hwiki(MW).
*/
/* Changelog
* 5/ 2/2012 - Better (though more fragile) click-to-toggle areas.
* 3/ 1/2012 - Fixed Chrome compatibility so it works! Doh.
* 23/ 3/2011 - Added Chrome compatibility.
