Svn: https://svn.osgeo.org/geos/tags/3.4.0


- New things:
  - Delaunay Triangulation API (#487, #565, #570, #567)
  - Interruptibility API (C and C++)
  - CAPI: GEOSNode (#496) - PHP: Geometry->node
  - GeometryPrecisionReducer class (#496, #526)
  - BufferInputLineSimplifier header exposed (#548)
  - New Centroid class supporting mixed geometry components (#612)
  - io::Writer::reserve() method
  - CAPI: GEOSNearestPoints
  - Add --cclibs, --static-clibs and --static-cclibs to geos-config (#497)
  - Early bail out of overlay exception if input is invalid

- C++ API changes:
  - New noding::GeometryNoder class
  - Added BufferOp::setSingleSided 
  - Signature of most functions taking a Label changed to take it
    by reference rather than pointer.
  - Signature of most functions taking an IntersectionMatrix changed
    to take it by reference rather than pointer.
  - GraphComponent::label is now a Label value (from a pointer)
  - NodedSegmentString takes ownership of CoordinateSenuence now
  - io::Writer's toString() returns by const ref, write() takes a const ref
  - Unify prototypes of WKTReader and WKBReader constructor (#310) 
  - GeometryCollection::computeEnvelopInternal and 
    GeometryCollection::compareToSameClass are marked virtual (#478)
  
- Bug fixes / improvements
  - A point interpolated from a line does not always intersect 
    the same line (#323) 
  - Port ConvexHull robustness fix from JTS-1.13 (#457)
  - Improve Overlay robustness by reducing input precision on topology
    exception and by refusing to accept unnoded output (#459)
  - Improve Buffer robustness by reducing input precision on topology
    exception (#605)
  - Mismatch segment sides in OffsetCurveBuilder (#633 )
  - Fixed Linear Referencing API to handle MultiLineStrings consistently
    by always using the lowest possible index value, and by trimming
    zero-length components from results (#323)
  - Fixed CMake configuration to set correct SOVERSION (current - age)
  - Fix EMPTY return from single-point lines and zero-length polygons (#612)
  - CMakeLists.txt, tools/geos_svn_revision_cmake.h.in: Add
	  geos_svn_revision.h generator to CMake config (#643)
	- Makefile.vc 'clean' step leaks obj files (#607) 


Please test and report any issues.

Thanks,
