I think it would be somewhat mad to try and make the interface express things
like "should be square, but doesn't have to be". I think having Gabble export
the requirements you suggest is fine, since it doesn't enforce them anyhow.
However, we should take care to report errors on setting the avatar back to
the client, in case the server actually decodes the image inside the vcard and
rejects it. What does the vcard manager do if the set-iq fails?
