 * $Log: RelateOp.cpp,v $
 * Revision 1.15  2004/07/27 16:35:47  strk
 * Geometry::getEnvelopeInternal() changed to return a const Envelope *.
 * This should reduce object copies as once computed the envelope of a
 * geometry remains the same.
 *
 * Revision 1.14  2004/07/02 13:28:29  strk
 * Fixed all #include lines to reflect headers layout change.
 * Added client application build tips in README.
 *
 * Revision 1.13  2004/03/29 06:59:25  ybychkov
 * "noding/snapround" package ported (JTS 1.4);
 * "operation", "operation/valid", "operation/relate" and "operation/overlay" upgraded to JTS 1.4;
 * "geom" partially upgraded.
 *
 * Revision 1.12  2004/03/01 22:04:59  strk
 * applied const correctness changes by Manuel Prieto Villegas <[e-mail]>
 *
 * Revision 1.11  2003/11/07 01:23:42  pramsey
 * Add standard CVS headers licence notices and copyrights to all cpp and h
 * files.
