Add rotation animation and custom animation curves

[sayho]

If you add rotation animations, there are more productions that users like me can do. And please add a custom curve to the Easing Function. It would be even better if we could add a custom curve preset.

That is great request, adding to backlog now! Regarding custom path - this is not as easy, but we want to add more capabilities in this are as well.

To be precise, it’s a custom curve in this part.

This is an animation editing curve that is common in Unity engines.
