Optimize views/grid

[aphyr]

Okay, excellent. So, let's assume there's no easy way to optimize the width changes. But we can very easily optimize everything else. Strip all the jQuery calls out of partialRender and renderElement. Don't look up any elements there either; cache your element lookups beforehand, ideally as raw DOM elements or arrays of DOM elements.

(12:18:30 PM) Aphyr: Yeah, I think you're right.
(12:18:32 PM) Ryan Grove: In Chrome and FF, you have a very good native querySelectorAll implementation, so jQuery is pretty unnecessary for that.
