Jonas Ådahl a48c9d6cd9 input-settings: Don't use screen limits when keeping aspect ratio
When no output was specified, the screen limit was used to calculate the
aspect ratio. The screen limit, however, is either just an arbitrary
number if no screen limit is applicable, or a hardware graphics buffer
limit, which has nothing to do with anything actually displayed. Change
it to use the screen size instead, to get something that makes more
sense when no output is found.
