Nit: I think calling this Create[...] is a little confusing because it's not a
constructor but a closer to something like Clone(). Maybe it would be more
straightforward to add a setter for the deadline.

True. I will change this to a setter for the deadline.

 
   // This is the default delta that will be used to adjust the deadline when
   // proper draw-time estimations are not yet available.
   static base::TimeDelta DefaultDeadlineAdjustment();
 
   base::TimeTicks frame_time() const {
     return frame_time_;
   }
