Summary:
* Any animation can be looped on the javascript thread
* Only basic animations supported natively at this stage, loops run
using the native driver cannot contain animations of type sequence,
parallel, stagger, or loop
Motivation: We need a spinner in our app that is displayed and animated while the javascript thread is tied up with other tasks. This means it needs to be offloaded from the javascript thread, so that it will continue to run while those tasks are churning away.
I originally submitted PR #9513, which has served our needs, but brentvatne pointed out a better way to do it. Had hoped his suggestion would be implemented by janicduplessis or another fb employee, but after 5 months I thought I'd give it another push.
I've put together an implementation that basically matches the suggested API. Let me know what you think, and whether others can pick it up from here and get it in to core.
Personal Motivation: I am leaving my current organisation on Feb 10th, so am trying to clean thing
