There are several variations on orientation. iOS expposes a little
more orientation information through its basic enum than Android
does, but the more powerful Android API gives you degrees around a
circle, which while strictly more powerful, doesn't tell you easily
where the status bar is.
What I'm thinking with this is the primary use of an orientation
concept is to decide whether or not to lay out a UI for a wide screen.
This gives you that.
Later I hope the sensor API will give far more information about the
physical orientation of the device.

This is analogous to the image.Image's Bounds method.
