IFTTAnimation accumulates errors in a subtle way. Every time you add an animation, the timeline gets one extra entry. Here's my fix. Note that the inner for-loop used to break when j <= nextKeyFrameTime. Suppose you have keyFrames at times 100, 200, and 300. With <= nextKeyFrameTime, you'll get two entries for time 100, 200, and 300, and you'll …
