(pt1: Vec2, pt2: Vec2, pt3: Vec2, pt4: Vec2, tension: number, continuity: number, bias: number): (t: number) => Vec2

A second order function returning an evaluator for the given 2D Kochanek–Bartels curve

param pt1- Previous point

param pt2- First point

param pt3- Second point

param pt4- Next point

param tension- The tension of the curve, [-1..1] from round to tight.

param continuity- The continuity of the curve, [-1..1] from box corners to inverted corners.

param bias- The bias of the curve, [-1..1] from pre-shoot to post-shoot.

returns A function which gives the value on the 2D Kochanek–Bartels curve at t
