 I agree about the page caching. If we do mess with the order, it will need
 to happen on the server side because anything we do in JS on the client
 side would cause a double download due to the preloader beginning to fetch
 the resource before JS is ready.

 Alternately, we could leave things as since iOS Safari 8 usage is below
 1%, according to [http://caniuse.com/usage-table StatCounter GlobalStats].
 Anyone who needs to support older versions of iOS can add a polyfill for
 `srcset`. It may not be worth the tradeoff of adding more overhead to a
 display filter to support such a small user base.
