CL 2132883002 changes the way Java Client is connected to the Java Display and make Java Display in charge of creating DesktopView. The cardboard renderer can no longer connect to the Java Display after this change. Since the cardboard feature is not under active development, there may be no urge to fix this. This bug is to leave a clue about how we can this problem.

To fix this, we can make Display a singleton, store the reference in a static field and pass it to the constructor of the cardboard renderer just like what we did for the Java Client.
