Yeah, I looked into this over the weekend, and -- shock! -- it turned
out to be a bigger change than I initially imagined. Since Chromium
has a different backend, that would mean implementing two sets of
changes.

Also, I think it would be wasteful to have WebKit download all linked
icons, even if the hosting browser has no intention of every using
some of them. So I'd want to add code to allow the browser to tell
WebKit which sizes it is interested in.

I still want to do this, but I'm going to have to reduce the priority
a little bit for now. I may come back to it in a month or so.
