    Description

      When the app is suspended by Android, we get a call to QAndroidPlatformIntegration::surfaceChanged().
      Then the surface disappears. We need to tell the app to stop rendering, and to resume rendering when we are restored.

      Gunnar said on IRC:
      QWindow::exposeEvent() + isExposed() is the one that can potentially wipe the entire rendering stack
      and it would also imply QQuickWindow::setPersistentSceneGraph(false) and QQuickWindow::setPersistentOpenGL(false) as the surface will disappear
