See b/214961273#comment1 and #comment2 for before/after videos as well as technical explanations on how this animation works. This CL also enables the generation of Java 8 default method bodies in interfaces, in the animation library. This is necessary to avoid unexpected behaviors when using @JvmDefault on an interface + delegation, which is a common pattern when using the animation library. See [1] and [2] for more info. Note that this is enabled only for the animation library (and not SystemUI(Lib)) to avoid breaking code depending on the (now deprecated) @JvmDefault method in SysUI.
