I've decided to fix this in a very explicit way. The only "magic" part that's left is how we decide that the AGR of the perspective item is outside the scrolled frame (and I'm not sure myself how that works). I didn't want to change what scroll clips we set on what items, because the scroll clip really belongs on the perspective item, because that's the item that needs to be clipped, and it should also be the item that should be scrolled if it weren't for the fact that APZ wouldn't know that it should apply the perspective transform before the APZ transform.
