Only defer transactions originating from repositionChild. There is no guarantee the frame we are suggested to synchronize to will ever arrive and synchronizing WM originated transactions to this can interfere with implementation of system policy. Anyway this code originally was fixing a case where transactions pushed by pulling down the notification shade, would interrupt animating SurfaceView's by pushing an undeferred transaction for those SurfaceView's. This doesn't seem to be occuring anymore even without this code. Furthermore even if it was occuring, we should prevent transactions from pushing updates for Surfaces where nothing has really changed, rather than attempt to chain the deferred transactions.
