- Setting exterior ring will force all interior rings to match dimensionality of exterior ring - add equality operator - use correct WKB types for rings when creating polygon from WKB - segmentize curves when setting exterior ring with curved segments - fix export to GML2/3 (should use LinearRing, not LineString as ring element tag)
