- Fix loss of coordinates when not rounding a particular dimension - Don't segmentize curved geometries - Add extra unit tests - Make createEmptyWithSameType() protected and skip from Python bindings. This method relies on low-level manipulation of the returned geometry which we do not want to expose as public/fixed API
