I'll use this thread to show progress on improving this animation. It will be very slow progress since I first have to develop the tools to do it ;-)

Here is the animation:

I have the same problem with the tweens, but in an even more problematic manner. Why do they react this way and sometimes don't do this "beyond keyframe interpolation"?

It's the same behaviour than what happens in 3D animation: by default, keyframe tangents are automatically computed in order for motion to be "smooth". A side-effect of this is that it generates "anticipation": the value would go slightly backward before going forward, to ensure smoothness. When it is not desirable, animators would manually edit the keyframe tangents in order to get what they want. Unfortunately, there is currently no way to do this in VPaint (i.e., manually editing tangents/trajectories), but I am planning to work on that sooner than later since it is a critical feature.
