Oops. If we were loading a banner where it was already loaded, we'd

see that it was loaded, and then load it--over a sprite that already had
it loaded, which caused it to get unloaded, lose refcount and get purged
and reloaded from scratch.

Just don't do that; always fade through the low-quality banner.
