 We still need a whitelist, so we wouldn't deviate from add_image_size().
 Otherwise you could just ++ the desired size, and force the server to
 continue to eat up resources in resizing photos. It's practically a DOS
 and would be death on a shared host.

 But what we could do, is generate those respective sizes on demand, when
 requested. This also allows for new ones to be generated on theme switch,
 again on demand.

 > I think we need something like this in core for 3.1, everyone needs it.
 No, this is two months too late for 3.1, and big enough that it would need
 to be a blessed task to be included in a release.

 Also, I found chatter in the IRC logs from March, where Mark was
 demonstrating what he was working on:

 dev&day=2010-03-11#m89606. Guess a ticket never came out of it.
