Maybe we should think of a way to expose _that_ information to CSS,
rather than going in the other direction.

  <img src="a.jpg" alt=""
       set="a.jpg 600x200 1x,
               b.jpg 600x200 2x,
               c.jpg 200x200">

section { /* generic style rules */ }
section! img:intrinsic-aspect-ratio(<2) { /* specific overrides for
section when the UA picks the narrow image */ }
