Summary: Modulus animation computation should use the value adjusted for offset, not the raw value. See the JS implementation here: https://github.com/facebook/react-native/blob/master/Libraries/Animated/src/AnimatedImplementation.js#L1338 cc ryangomba Closes https://github.com/facebook/react-native/pull/15502 Differential Revision: D5638901 Pulled By: shergin fbshipit-source-id: cbf47bd4082897a969e2e561ec090366884a8349
