If you think that's confusing, wait until you try to use an external monitor
and see what the rotation does to you. So far, I've successfully managed to
counter-rotate the external view's window so my text stays upright, but
getting the view and its contents to scale properly is proving more elusive.
I'm not even sure I know x from y or width from height in this environment.
