settle

Find the closest anchor, taking into account the velocityThreshold and positionalThreshold, and settle at it with an animation.

If the velocity is lower than the velocityThreshold, the closest anchor by distance and positionalThreshold will be the target. If the velocity is higher than the velocityThreshold, the positionalThreshold will not be considered and the next anchor in the direction indicated by the sign of the velocity will be the target.

Based on the velocity, either snapAnimationSpec or decayAnimationSpec will be used to animate towards the target.
