    00207  * $Log$
    00208  * Revision 1.8  2006/06/12 10:10:39  strk
    00209  * Fixed getGeometryN() to take size_t rather then int, changed unsigned int parameters to size_t.
    00210  *
    00211  * Revision 1.7  2006/05/04 15:49:39  strk
    00212  * updated all Geometry::getDimension() methods to return Dimension::DimensionType (closes bug#93)
    00213  *
    00214  * Revision 1.6  2006/04/28 10:55:39  strk
    00215  * Geometry constructors made protected, to ensure all constructions use GeometryFactory,
    00216  * which has been made friend of all Geometry derivates. getNumPoints() changed to return
    00217  * size_t.
    00218  *
    00219  * Revision 1.5  2006/04/10 18:15:09  strk
    00220  * Changed Geometry::envelope member to be of type auto_ptr<Envelope>.
    00221  * Changed computeEnvelopeInternal() signater to return auto_ptr<Envelope>
    00222  *
    00223  * Revision 1.4  2006/04/07 09:54:30  strk
    00224  * Geometry::getNumGeometries() changed to return 'unsigned int'
    00225  * rather then 'int'
    00226  *
    00227  * Revision 1.3  2006/03/24 09:52:41  strk
    00228  * USE_INLINE => GEOS_INLINE
    00229  *
    00230  * Revision 1.2  2006/03/23 12:12:01  strk
    00231  * Fixes to allow build with -DGEOS_INLINE
    00232  *
    00233  * Revision 1.1  2006/03/09 16:46:49  strk
    00234  * geos::geom namespace definition, first pass at headers split
    00235  *
