 * Returns a `MotionValue` each for `scaleX` and `scaleY` that update with the inverse

 *
 * This is useful for undoing the distortion of content when scaling a parent component.
 *

 * By passing other `MotionValue`s in as `useInvertedScale({ scaleX, scaleY })`, it will invert the output
 * of those instead.
