Moving pivot animation pipeline

The main idea is to animate pivot and object at the same time. There are a lot of situations where we need some control like this.

Example:
You need to roll the foot over a ball. Character just touch a ball by his leg hill and need to roll to the tip of the foot. Movement must be non-linear because the point of contact always moves while foot it moving and rotating.
