c6c26d5d44 Change Terrain so that it subclassed from CoordinateSystemNode.
Implemented new update scheme of GeometryTechnique to avoid potential threading issues.

Added Terrain support to .ive.

5cd4faf05b From Jason Beverage, "I posted a question on osg users about resources not being properly released when using osgTerrain databases and multiple viewers are used a few weeks ago and I've found that at least part of the problem comes down to the fact that the nodes that are traversed by the GeometryTechnique are never actually added to the scene graph, and thus don't have releaseGLObjects called on them. I'm submitting a few changes that takes care of this by allowing the TerrainTechnique to provide a releaseGLObjects implementation. I've applied these changes in osgEarth and this example program no longer crashes on the second run, although I get corrupt geometry (see attached shot) which could be down to a driver issue. If I increment the context ID for the second viewer, I no longer get the corrupt geometry.
The attached changes are against OpenSceneGraph 2.8.2.

//Sample program.  Run against an osgEarth or VPB database based on osgTerrain.
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>

int main(int argc, char** argv)
{
   osg::ArgumentParser arguments(&argc,argv);

   osgViewer::Viewer* viewer = new osgViewer::Viewer();
   viewer->setUpViewInWindow(100,
100,500,500);
   osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFiles(arguments);
   viewer->setSceneData( loadedModel.get() );
   viewer->run();
   delete viewer;

   viewer = new osgViewer::Viewer();
   viewer->setUpViewInWindow(100,100,500,500);
   loadedModel = osgDB::readNodeFiles(arguments);
   viewer->setSceneData( loadedModel.get() );
   viewer->run();
   delete viewer;
}"

4d60d73eca Reorginized the TerrainTile/TerrainTechnique dirty mechanism so that TerrainTile
now holds the dirty flag and enables/disables event traversal in response dirty
being set/unset.  This allows terrain to be automatically updated in response
to Terrain scale and sample ratio changes.

2f41234793 From Maria Ten, "I divide the init method of the
geometrytechnique in submethods to made more easy the inheritance
between the user and osg-class. This is a first step to add more
functions in osgTerrain. Maybe the subdivision of the method have to
be in the terraintechnique because is the base class of
GeometryTechnique. If Robert or anyone think that this is better i
change this class too."

eac3dc1963 From Paul Melis, "Here is a list of fixes to misspelled APIs. Unfortunately, more than one
of these are public APIs and therefore will break linkage to existing
shared libraries."
