- Consolidate Skottie logic into SkottieViewController class that no longer
knows about which backend we use.
- Abstract out SkiaViewController interdace which SkottieViewController
implements.
- Create three classes SkiaGLView, SkiaUIView, and SkiaMtkView, which all
accept SkiaViewController objects but override GLKView, UIView, and
MTKView.
- SkAnimationDraw and SkTimeKeeper now SkiaViewController
implementation details, no longer shared in headers.
