fletcher.paths.cubic-arc()

Approximate a circular arc with a cubic Bézier segment.

This similar to cetz.drawable.arc() except that it never uses more than one cubic Bézier segment, and it returns just the control and end points (c1, c2, e), not a path.

Single segment approximations are useful because they are more visually robust to nudging endpoints, which is sometimes necessary when creating a rounded corner where two curves meet.
