Subject: [PATCH] Optimized `TweenData.update` to achieve the same result with
 my less repetition. Also fixes an issue where a Tween that used a custom
 `ease` callback would glitch when the final value was set, as it would be set
 outside of the ease callback. It's now passed through it, no matter what. Fix
 #6939
