Centering in landscape

When I run your Hello World demo in landscape, there seems to be a problem with horizontal centering of subviews created in the `viewDidLoad` method. This problem persists with views created in new ViewControllers created later.

The problem can be corrected by running `rmq.all.reapply_styles` after the view is visible. I'm not sure what causes it. Rotating also fixes it. It really only appears when content is setup in `viewDidLoad`. It may have something to do with device/view rotation since it's always correct in portrait.

Start with the Hello World demo and trace views created in viewDidLoad, then compare initial landscape layout with portrait and with a later rotation. Investigate the timing around view visibility and the existing rmq.all.reapply_styles workaround. Done means subviews are horizontally centered on the first landscape display without requiring reapply_styles or rotation.
