This test can be used to verify that we preserve the specified viewport initial-scale on rotation.

This test PASSED if the text in the blue square (below) reads "window.innerWidth: 360"(*) when rotating from portrait- to landscape- orientation, and vice-versa. Otherwise, it FAILED.

(*) Note, this test is platform-specific. For example, on an iPod Touch, the text in the blue square should read "window.innerWidth: 320" since the width of its screen in direction north is 320 pixels.
