From Geoff Michel, "New delaunay triangulator attached. I hadn't realised that the erase() method was not erase (first, last) but erase (first, one after the last one you want deleted). This made a big difference; however some of the edges of the terrain were not included as edges in the terrain so I increased the size of the supertriangle, which works but reduces accuracy due to the larger range of coordinates in the supertriangle. (A larger supertriangle forces the triangles using supertriangle vertices to be long and thin, making the triangulation fit the convex hull of the terrain.)
...
The loss of accuracy should not affect 'normal' users with terrains that are roughly square (say up to 100:1 aspect ratio) and where the Z range is comparable to the X-Y range. Retested with Pauls data, amalric's strange polygon constraint and the standard test constraints.
I also added 2 tests for routines with a NULL argument passed to them (no-one would usually pass a NULL pointer to these routines unless - as I did in testing- you remove some of the constraints but still pass their pointer to the routine). And I removed 3 tests for triangles which are already removed when generating the geometry.
NB Paul - the previous delaunay triangulator fails under VS8 IF it has any constraints as it attempts to use some vertices that have already been deleted when applying the constraints to edges. Under VS6 and less rigorous compilers it works as the deleted vertices are still in the points stl::Vector; however any added vertices would replace one of the supertriangle vertices with non-disastrous but wrong results."
Note, merged with latest name changes in CVS.

From Geoff Michel, "I was getting triangulations with the previous delaunay triangulator, but it seems I may have been picking up the wrong coordinates or an old version of my test file (that version is OK when no coordinates lie outside the 'terrain' zone). This version is much stricter about memory handling and insertion of extra points."

Added support for float or double osg::Plane, and the default osg::Plane to double.
...
Performance tests on big models did not indicate any performance penalty in using doubles over floats,
so the move to doubles should mainly impact precision improvements for whole earth databases.
Also made improvements to osgUtil::PlaneIntersector and osgSim::ElevationSlice classes

Fixed fade text memory consumption bug which was due to new RenderInfo being
...
created local to RenderStage and passed on to rendering code which populated
the RenderInfo UserData, but without the restoring the new UserData to the
main RenderInfo. The local RenderInfo UserData is now passed back to the main
RenderInfo.

From John Aughey, "Attached is the Optimizer.cpp file that has the fix to duplicate vertex and normal arrays if there is more than one reference to the data.
