In some cases, we may be using neither "Auto Layout" nor "Springs and Struts",
and may instead be completely managing our layouts programatically. For
example, if we wanted to replicate the behavior of Apple's camera app where
the "record" button is always fixed to the bottom of the _device_ rather than
the bottom of the _view_. In these cases, we want to use the orientation of
the _device_ rather than the orientation of the status bar.
