------- Additional Comments from Peter Kasting <pkasting at google.com>
Some cleanup and plumbing I split out of the next patch (which, finally,
implements the desired behavior), in order to make it more readable.

Mainly, this adds a new function ImageDecoder::frameSizeAtIndex(), and hooks
the ImageSource::frameSizeAtIndex() implementations to it; no decoder actually
implements it yet (the ICO decoder will after the next patch).
