### Cubic Bezier curve sections

Up to 34 control points may be set, giving a maximum of 11 cubic Bezier
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 Bezier 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 on that line in order for the curve to be C1 continuous
at the connecting point.
