VectorizedRepeatableSpec  
  constructor(iterations: Int, animation: VectorizedDurationBasedAnimationSpec<V>, repeatMode: RepeatMode = RepeatMode.Restart, initialStartOffset: StartOffset = StartOffset(0))
Parameters
iterations
the count of iterations. Should be at least 1.
animation
the VectorizedAnimationSpec describing each repetition iteration.
repeatMode 
whether animation should repeat by starting from the beginning (i.e. RepeatMode.Restart) or from the end (i.e. RepeatMode.Reverse)
initialStartOffset  
offsets the start of the animation
