Add support for native animations on iOS Summary: Currently on iOS animations are being performed on the JS thread. This ports animations over to the native thread and performs them natively. A lot of this work has already been done on Android, but this PR enables a few animation nodes that Android doesn't yet support such as Transform, Multiplication, and Addition nodes. Also there is a demo of the native animations added to the UIExplorer app. Closes https://github.com/facebook/react-native/pull/7884 Reviewed By: javache Differential Revision: D3409179 Pulled By: nicklockwood fbshipit-source-id: ef2d8840032e0c32f49e4a16ba86d448662e1751 2016-06-09 10:34:41 -07:00			`/**`

Maintain transform order Summary: This diff addresses the issues raised by kmagiera in https://github.com/facebook/react-native/pull/7884. Transforms should be applied in the order they are defined, just like in `processTransform.js`. A scale applied before a translation, for instance, should give a different result than a translation applied before a scale. We leverage CATransform3D to do the heavy lifting. A concatenated transform is passed all the way to `RCTViewPropertyMapper`. It is compared with the transform currently applied to the view, and if different, applied. The same approach is used for opacity. I think it makes the most sense to do this diffing in `RCTViewPropertyMapper`, as opposed to creating and cleaning up an `_updatedPropsDictionary` each frame in `RCTTransformAnimatedNode` and `RCTStyleAnimatedNode`. The node should keep its full value; applying a minimal set of altered props is an optimization. The higher up this optimization is implemented, the more assumptions it makes. e.g. that there will only ever be a sing Closes https://github.com/facebook/react-native/pull/9050 Differential Revision: D3658139 fbshipit-source-id: ad6286762ef734084cbdf83c9bd9241190302d34 2016-08-02 14:23:18 -07:00			`- (NSDictionary<NSString , NSObject > *)updatedPropsDictionary;`
