Well, but not resizing isn't possible, then it wouldn't have the right aspect! (Well, nowadays we could fix that by adding black bars I guess, but I still kind of assume that if you run in a window you don't want that).
No question that it feels a bit strange though.

Hmm, I think we might have set aspect functions that do this fact.
