Introduced AnimatedDivision Summary: Combining 2 animated values via addition, multiplication, and modulo are already supported, and this adds another one: division. There are some cases where an animated value needs to invert (1 / x) another animated value for calculation. An example is inverting a scale (2x --> 0.5x), e.g.: ``` const a = Animated.Value(1); const b = Animated.divide(1, a); Animated.spring(a, { toValue: 2, }).start(); ``` `b` will then follow `a`'s spring animation and produce the value of `1 / a`. The basic usage is like this: ``` <Animated.View style={{transform: [{scale: a}]}}> <Animated.Image style={{transform: [{scale: b}]}} /> <Animated.View> ``` In this example, the inner image won't get stretched at all because the parent's scaling gets cancelled out. Also added this to native animated implementation.
