Make scroll physics core objects
Browse files Browse the repository at this point in the history 
Set up scroll physics as core objects with 2 options (Clamped and Elastic - open to better names). In addition, we expose 3 knobs for the Elastic physics:
1. Friction - the strength of the deceleration of the scroll after release
2. Speed multiplier - determines the initial speed at release
3. Elastic factor - determines the strength of the rubber banding

Maybe we want to normalize them to values between 0-100 or 0-1?
