Detailed Description

A polygon: exactly one exterior ring + zero-or-more interior rings.

Orientation convention after normalizeRingPolygon(): exterior is counter-clockwise (positive signed area), interiors clockwise (negative signed area). Consumers that care about ring winding (e.g. Shapefile export) may rely on that post-normalize.
