approximateCurve :: CubicBezier -> [Point] -> Double -> (CubicBezier, Double, Double)Source
approximateCurve b pts eps finds the least squares fit of a bezier
curve to the points pts. The resulting bezier has the same first
and last control point as the curve b, and have tangents colinear with b.
return the curve, the parameter with maximum error, and maximum error.
Calculate to withing eps tolerance.
approximateCurveWithParams :: CubicBezier -> [Point] -> [Double] -> Double -> (CubicBezier, Double, Double)Source
Like approximateCurve, but also takes an initial guess of the parameters closest to the points. This might be faster if a good guess can be made.
