ReadonlyringTotal number of rings (outer boundaries and holes).
ReadonlyshapeNumber of outer boundaries.
Every ring's plane coordinates concatenated, [u0, v0, u1, v1, …].
What the run did: cell size, cap hits, ring counts, repairs.
Vertex count of each ring, in coords() order.
The ring directly containing each ring (a hole's outer boundary, an
island's hole), or -1 at top level.
Ring index at which each shape starts; entry s is shape s's outer
ring and the rings up to the next entry are its holes.
Every ring mapped through the plane frame, [x0, y0, z0, …] in
coords() order, or undefined when no frame was given.
