Calculates coordinates along a Bézier curve using interpolation.
bezierPoint() calculates coordinates along a Bézier curve using the anchor and control points. It expects points in the same order as the bezier() function. bezierPoint() works one axis at a time. Passing the anchor and control points' x-coordinates will calculate the x-coordinate of a point on the curve. Passing the anchor and control points' y-coordinates will calculate the y-coordinate of a point on the curve.
The first parameter, a, is the coordinate of the first anchor point.
The second and third parameters, b and c, are the coordinates of the control points.
The fourth parameter, d, is the coordinate of the last anchor point.
The fifth parameter, t, is the amount to interpolate along the curve. 0 is the first anchor point, 1 is the second anchor point, and 0.5 is halfway between them.
