A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/1306883009/ by bajones@chromium.org.

The reason for reverting is: Reason for revert was a misunderstanding of issues
that another piece of code was having interacting with the Cardboard SDK. This
code was not exhibiting the same problems, so restoring it while we investigate
the other code's issues further..
