[whatwg] srcset javascript implementation (Respondu)

[David Clements]

Hi guys,

Just to let you all know, I've written a javascript implementation of
srcset using a framework for responsive images (which I also wrote)
called Respondu (I'm open to new name suggestions), I'd love it if someone
could check that I've implemented srcset right.

Respondu manages to process the DOM without allowing any assets (contained
in the body) to load, it also gracefully degrades for non-js
browsers and is fairly unintrusive (it simply wraps the contents of the
body tags).

Check out the github page (feedback, pull requests, lunch money etc.
welcome)

You can also see working examples at

http://respondu.davidmarkclements.com/

The framework, and srcset implementation are currently in alpha - its not
presently compatible the document.ready et. al., however
you can simply put scripts at the bottom of the body instead (which is best
practice in most cases anyway).

So far, it's tested and works in ie8, chrome, firefox, and iOS safari.

Let me know if it works/doesn't work in other browsers!

All the best,

Dave
