FYI: playing fullscreen video in the WebView requires hardware acceleration. See
the documentation in
http://developer.android.com/reference/android/webkit/WebView.html or
b/15021171. 

The reason why this test was passing before is because we have changed the
timing of events. The hardware check only happens when we first try to draw into
the custom ViewGroup. We now try to draw into the custom ViewGroup before
creating the ContentVideoView, the check fails, so we don't create the
ContentVideoView. Before we were creating the ContentVideoView before the first
draw.

We should add a test that video in software mode doesn't cause deadlocks etc.

     @Feature({"AndroidWebView"})
     @SmallTest
     public void testGetVideoLoadingProgressView() throws Throwable {
         TestAwContentsClient contentsClient =
                 new FullScreenVideoTestAwContentsClient(getActivity()) {

                     protected View getVideoLoadingProgressView() {
                         View view = new View(getInstrumentation().getTargetContext());
                         view.addOnAttachStateChangeListener(
