I do have the same concern over terse names. I don't see any point in
saving 13 bytes by abbrebiating DevicePixelRadio as DPR.
In the case of ResourceWidth, we can't get this number until we trigger a
layout. It doesn't seem desirable to slow down the page load speed by
eagering triggering layout before loading each image. How do we plan to
work around that?
