 // It might be nice not to have the ::current() call and put all of the
 // functions on the abstract class so they can be mocked. However, there are
 // some standalone functions like in ChromiumBridge that are not associated
 // with a view that need to access the current thread to send messages to the
 // browser process. These need the ::current() paradigm. So instead, we should
 // probably remove the render_thread_ parameter to RenderView/Widget in
 // preference to just getting the global singleton. We can make it easier to
 // understand by moving everything to the abstract interface and saying that
 // there should never be a NULL RenderThread::current(). Tests would be
 // responsible for setting up the mock one.
