Simplfifer::ContinueSimplificationCallback to be able to decide whether up or downsampling is required,
removing the previous hardwards reliance on getSampleRatio<1.0.
forcing users to use osgDB::readRef*File() methods. The later is preferable as it closes a potential threading bug when using paging databases in conjunction
with the osgDB::Registry Object Cache. This threading bug occurs when one thread gets an object from the Cache via an osgDB::read*File() call where only
a pointer to the object is passed back, so taking a reference to the object is delayed till it gets reassigned to a ref_ptr<>, but at the same time another
thread calls a flush of the Object Cache deleting this object as it's referenceCount is now zero. Using osgDB::readREf*File() makes sure the a ref_ptr<> is
passed back and the referenceCount never goes to zero.
To ensure the OSG builds when OSG_PROVIDE_READFILE is to OFF the many cases of osgDB::read*File() usage had to be replaced with a ref_ptr<> osgDB::readRef*File()
usage. The avoid this change causing lots of other client code to be rewritten to handle the use of ref_ptr<> in place of C pointer I introduced a serious of
templte methods in various class to adapt ref_ptr<> to the underly C pointer to be passed to old OSG API's, example of this is found in include/osg/Group:
bool addChild(Node* child); // old method which can only be used with a Node*
tempalte<class T> bool addChild(const osg::ref_ptr<T>& child) { return addChild(child.get()); } // adapter template method
These changes together cover 149 modified files, so it's a large submission. This extent of changes are warrent to make use of the Object Cache
and multi-threaded loaded more robust.

This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

It should stop and wait for a signal on either of those two. Due to a few logical inversions it boils down to replacing || with &&
OLD _block->set((!_requestList.empty() || !_pager->_databasePagerThreadPaused));
NEW _block->set((!_requestList.empty() && !_pager->_databasePagerThreadPaused));//release the threads to run IF (work_to_be_done && not_paused)
This bug is present since svn rev 8663 (just before 2.6.0 release)
attached is a zip with the files:
OpenSceneGraph\include\osgDB\ImagePager
This file is valid for svn branch and stable 3.2 and 3.4
branches 2.6 - 3.0 have the same bug, but other differences in the file."

I used osgSetGLExtensionsFuncPtr to remove the symbols. I don't know how to test this path, but it did remove the symbols from libosgViewer.so. I have also not been able yet to see if that was sufficient for our customer.
I did this by looking at other cases, and I tried to follow some of the same practices in PixelBufferX11, like using _useSGIX in a similar way to the previous _useGLX1_3."

When an application is built with Qt4, but osgQt was built with Qt5 (or vice versa), upon #includeing osgQt users will receive an #error aborting the build.
This at least provides a proper error message rather than a crash, while we are working on better fixes for the problem."

osg::UniformCallback inherits osg::Callback now.
I don't really now if this class should be inside osgWrappers/serializers
because StateAttributeCallback is not presented there, but i've included it in the patch.
Please see archive in the attachment.
PS
DEEP_COPY_UNIFORMS works for me.

Note from Robert Osfield, added typedef UniformCallback Callback for backwards compatibility.

I have left the Texture::generateTextureObject functions intact as I'm not sure if/how it's used outside the core OSG. If you feel that compatibility isn't important in that area feel free to drop it.
While testing the build with OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION=OFF I found a compile error in GlyphGeometry.cpp that was entirely unrelated to the changes I've made. The fix is included in the patch.
There is one thing left to fix and that is Texture2D::SubloadCallback:
class OSG_EXPORT SubloadCallback : public Referenced
{
public:
....
virtual TextureObject* generateTextureObject(const Texture2D& texture, State& state) const
{
return osg::Texture::generateTextureObject(&texture, state.getContextID(), GL_TEXTURE_2D);
}
...
}"
