With that said, I tested your PR, and zooming still seems pretty broken to me. For one, I don't notice much of a difference except for the animation. Secondly, I think a big part of what makes the zooming feel erratic is there's this "frame" around the scene that forces the zooming to take strange turns. If you'd like, maybe we can talk over zoom ( ;) ) about the zooming behavior?

@tobiasholenstein Wanna try it soon :)
