a53308f7e8 Gunnar Holm, "After upgrading from 2.8.3 to 3.0.1 we experienced a lock in the Mutex 
functionality when using Terrain::setVerticalScale. This was caused by
the following call sequence resulting in a lockup:

void Terrain::setVerticalScale(float scale)
  CALLS    dirtyRegisteredTiles();


void Terrain::dirtyRegisteredTiles(int dirtyMask)
 SETS LOCK    OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
 and CALLS (on every tile)   setDirtyMask(dirtyMask);


void TerrainTile::setDirtyMask(int dirtyMask)
 CALLS _terrain->updateTerrainTileOnNextFrame(this);


void Terrain::updateTerrainTileOnNextFrame(TerrainTile* terrainTile)
 SETS LOCK   OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
******* PROBLEM - since lock has already been set! ********


The suggested fix submitted changes from using Mutex to ReentrantMutex.

d3d0859b4c From Piotr Gwiazdowski, "So there's config setting OSG_DISABLE_MSVC_WARNINGS which should 
disable pragmas that turn off specific warnings for MSVC.
Unfortunately it's presence is only checked in osg/Export header,
making other Export headers disable warnings no matter what, which is
kind of incoherent.

My fix adds #include <osg/Config> to every Export header. I've also
unified checking whether to disable warnings to current osg/Export
way:
#if defined(_MSC_VER) && defined(OSG_DISABLE_MSVC_WARNINGS).

Attachment contains all changed Export files in their original locations."

f61a6aa4e7 Refactored the way that the DatabasePager passes the Terrain decorator node onto the TerrainTile. 
The DatabasePager now passes the Terrain pointer into the ReaderWriter's via osgDB::Options object,
rather than pushing a NodePath containing the Terrain onto NodeVisitor.  This
change means that the DatabasePager nolonger needs to observer the whole NodePath and
will be lighter and quicker for it.

The change also means that ReadFileCallback can now run custom NodeVisitor's on the scene graph without
having to worry about TerrainTile's constructing scene graphs prior to the Terrain being assigned.

Also changed is the NodeVisitor::DatabaseRequestHandler which now requires a NodePath to the node that you wish
to add to rather than just the pointer to the node you wish to add to.  This is more robust when handling scenes
with multiple parental paths, whereas previously errors could have occurred due to the default of picking the first
available parental path.  This change means that subclasses of DatabasePager will need to be updated to use this new
function entry point.

526b39060c From Brad Christiansen and Robert Osfield, "I have added the new function as suggested. The change was made against trunk from an hour or so ago. I haven't tested the performance yet (and probably won't get a chance till next week) but I have checked my terrains still work. I defaulted the equalization to off as I thought this was best until we can look into why there is the performance hit. 
", note from Robert, tweaked the names and enabled the code path.

fccda08491 Added corner dirty options to TerrainTechnique, added experimental code paths in GeometryTechnique for accounting for neighbouring corner tiles - optionally compiled out in this check-in. 
Changed the normal computation in GeometryTechnique so that it doesn't include diagonals, thus avoid normal jumps at corners.

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.

      terrain = new osgTerrain::Terrain;
      terrain->addChild(model.get());
