Use final newton root refinement in cubic roots solve to refine accuracy
For clip intersections (xPoints, yPoints), ensure x(t) or y(t) are outside of the clip (side issue) => extra clip padding will then be useless (1.0 for float, 0.25 for double variants) as roots do not ensure enough precision on the point coordinates for now

Really worth to improve 2nd and 3rd order polynom solver in Marlin-math:
