Improved results for paths with partially intersecting bezier curves.
The curve-curve intersector can now detect when curves partially overlap and correctly determines the endpoints of the overlapping section.
The intersection point filter now preserves the correct curve control points for curves that intersect at their endpoints.
Improved accuracy of line-curve intersection and curve control point finding.
Cubic curve root finder now has a “greedy” option that allows it to search for points that are “almost” roots. This is helpful for overcoming numerical precision problems when searching for the parameter for a curve point at the minima or maxima of the curve.
