* $Log$
* Revision 1.8 2006/06/12 10:10:39 strk
* Fixed getGeometryN() to take size_t rather then int, changed unsigned int parameters to size_t.
*
* Revision 1.7 2006/05/04 15:49:39 strk
* updated all Geometry::getDimension() methods to return Dimension::DimensionType (closes bug#93)
*
* Revision 1.6 2006/04/28 10:55:39 strk
* Geometry constructors made protected, to ensure all constructions use GeometryFactory,
* which has been made friend of all Geometry derivates. getNumPoints() changed to return
* size_t.
*
* Revision 1.5 2006/04/10 18:15:09 strk
* Changed Geometry::envelope member to be of type auto_ptr<Envelope>.
* Changed computeEnvelopeInternal() signater to return auto_ptr<Envelope>
*
* Revision 1.4 2006/04/07 09:54:30 strk
* Geometry::getNumGeometries() changed to return 'unsigned int'
* rather then 'int'
*
* Revision 1.3 2006/03/24 09:52:41 strk
* USE_INLINE => GEOS_INLINE
*
* Revision 1.2 2006/03/23 12:12:01 strk
* Fixes to allow build with -DGEOS_INLINE
*
* Revision 1.1 2006/03/09 16:46:49 strk
* geos::geom namespace definition, first pass at headers split
*
