NSApplicationDidChangeScreenParametersNotification
It doesn't have userInfo, so you'll still have to save the last known screen bounds yourself.

I don't see any notifications that look like NSWindowScreenSizeDidChange. Where would I catch these "window is moving because the screen changed size" messages? I tried adding a NSWindowDidChangeScreenNotification handler, which *does* get called when changing a screen's size, but the notification doesn't contain the old screen size, so I can't move it appropriately. Arg. There's no accompanying NSWindowWillChangeScreenNotification in which to store the old screen size.
