* `Tween.init` and `Tween.play` have been rewritten so they are not run multiple times when a Tween is paused before playback, or is part of a Timeline. This didn't cause any problems previously, but it was a redundant duplication of calls.
* `Tween.onLoop` will now be invoked _after_ the `loopDelay` has expired, if any was set.
* `Tween.onRepeat` will now be invoked _after_ the `repeatDelay` has expired, if any was set.
* `easeParams` would be ignored for tweens that _didn't_ use a string for the ease function name. Fix #3826 (thanks @SBCGames)
* You can now specify `easeParams` for any custom easing function you wish to use. Fix #3826 (thanks @SBCGames)
