Cubic Bézier curve sections

Up to 34 control points may be set, giving a maximum of 11 cubic Bézier curve sections (the last point of each section is the first point of the next section).

Click on "Display convex hull" and move the points around to see that a Bézier curve always stays within the convex hull of its control points.

Click on "Display C1 continuity hint" to see a line going through the third and fourth point of each section. The second point of the next section should be at the other end of that line in order for the curve to be C1 continuous at the connecting point.
