We should have a Widget that takes two build functions as constructor arguments and calls one or the other based on whether the aspect ratio it is to be laid out in is horizontal or vertical.

Maybe this should be a layout callback case.

Ideally this would be written is such a way as to be ready to handle iOS-style rotation animations.
