New Revision: 3340

Modified:
   trunk/include/geos/algorithm/LineIntersector.h
   trunk/include/geos/geomgraph/EdgeIntersection.h
   trunk/include/geos/geomgraph/EdgeIntersectionList.h
   trunk/src/algorithm/LineIntersector.cpp
   trunk/src/geomgraph/Edge.cpp
   trunk/src/geomgraph/EdgeIntersectionList.cpp
Log:
Revert "Use long double to compute edge distance." (r3334). Simple double in HCoordinate made #350 pass anyway.
