* Pack OutputObject bitfields more efficiently * Move to plain enum to keep GCC happy * Convert int40 to string * Cast bitfield as a full int for logging * Make enum names unique, because Windows * Fake relation id shouldn't overtop the bitfield * Pack into 36 bytes * Improved simplify performance (#279) * Remove reference counted outputobject * Use OsmID to lookup generated geometry * Remove temporary when assigning multipolygon * Make attribute store ref an intrusive pointer Co-authored-by: systemed <richard@systemeD.net>
