	enne (OOO) 2016/03/28 21:43:27 In order to stage Android (and renderers) separate In order to stage Android (and renderers) separately, I've put in a LayerTreeSetting for whether or not the output surface's begin frame source should be used. If the setting is off, then OutputSurfaceClient::SetBeginFrameSource is ignored. If the setting is on, then SingleThreadProxy ignores external/unthrottled/synthetic begin frame sources and only uses the one set by the OutputSurface and is otherwise null. That seems like a reasonable way to stage this for different compositors and platforms, and also to make sure that this is behaving in a "real" way rather than depending (briefly) on a fake begin frame source that gets clobbered.
