/************************************************************************************
Filename : Q2VR_SurfaceView.c based on VrCubeWorld_SurfaceView.c
Content : This sample uses a plain Android SurfaceView and handles all
Activity and Surface life cycle events in native code. This sample
does not use the application framework and also does not use LibOVR.
This sample only uses the VrApi.
