@Raynos what's wrong with using querySelector?

[Raynos]

@jprichardson doesn't work in legacy browsers. That and it's simply slower then gEBTN. The latter is faster and has better browser support so win/win.

Also note that the bulk of the jQuery removal fix was done in the other commit I made. Removing qs was just a minor tweak I made to that commit.

@Raynos ...

@jprichardson doesn't work in legacy browsers.

That argument doesn't hold when you haven't replaced the use of canvas...

[rauchg]

The canvas is just a fancy addition though. We don't need to have that for unfancy browsers.
If I remember correctly I was doing a check for the existence of getContext, so it shouldn't break.

True enough. Strike last comment
