why is this pass by value? I'd either expect a const ref or a pointer

My bad ... the function modifies the vector (via swap), so it should have been a
pointer. Since we generally have few, if any, sequences in the vector copying
isn't *totally* awful, but I think we want to be clear that SwapDelegatedFrame
is 'consuming' the sequences in this vector.

Fixed.

   void WasShown(const ui::LatencyInfo& latency_info);
   void WasResized();
