Deleted this line while cleaning up vsync functions in DFH because it seemed
spurious.  The DFH already gets vsync updates from the vsync manager and doesn't
need another path to redundantly do it.

   host_->Send(new ViewMsg_BeginFrame(host_->GetRoutingID(), args));
   last_begin_frame_args_ = args;
