Check every cone point on its own ray, and unwrap angles forward

The exactness check found its bracketing probes by recomputed angle,
which twice let a broken outline through: steps between points wider than
half a turn unwrapped backward, and cones narrower than 1e-7 radians had
no probes at all. Outline points come in increasing ray order, so angles
now unwrap forward only, the last point is pinned to the cone's far edge,
and every point must also lie where the ray toward it ends, which needs no
bracketing. Test cases for both holes check the check.
