Orientation Support Mobile

Mon Sep 8 13:57:00 EDT 2014

Also, Ralph, to your original suggestion, I'm not looking to support
orientation changing, initially, I'm looking to have some cards render one
way and some the other way.  When you have everything accept both
orientations, you wind up with a situation where you also have to move
controls to support the keyboard on the bottom of the screen, especially in
landscape.
