I think the tiles at home folks already keep a database that says how
complex each level-12 tile is. So if we were not so busy telling them
how they're technologically backwards and how their whole project is
rubbish, they might just give us that.
I also suspect that the size of a PNG tile would bear a halfway linear
relationship to the amount of data on that tile, so a HEAD request
against the tile server could work just as well.
