Not my idea, but certainly a good one. :)

I was wrong, :filter is available, I'll have a bit more of a think
about what we want to call it.

As for default behaviour, I'm inclined to stick with what we have
where scaling down uses best and scaling up uses nearest neighbour but
any use of :filter (or whatever) over-rides the default. Anyone have
an opinion? Do we just want to use best everywhere by default?
