I'd like a way to chain performances together.

Sometimes animations are too complex to easily define in terms of one performance. It would be nice if one could chain performances together. For example: I'd like to be able to say that performance B should begin when performance A passes t=0.5 or when performance A starts or ends.

There's a bunch of variants:

• Sequential composition
• Parallel composition

We have this, you can now write a method with "async" and "await" that runs different controllers in sequence.
