Transitions broken on the donut chart example

[Mark Daggett]

@nsonnad just noticed that the refactoring you did to the arc series seems to have broken the transitions between pie slices. If you notice the donut chart example now snaps to the next location where it used to animate nicely between states. This is a minor defect but I worry that it is a symptom of a larger problem. I've not looked at the issue yet it might be minor, I just thought i'd run it by you first.

Please note that the text labels still nicely transition between states.
