destruction of RequestQueue to remove any pointers held in DatabaseRequest attached to the scene graph, and to
prevent their subsequent use in cases where the scene graph is attached to a new DatabasePager.
to the osgDB::Registry. Added a osgDB::Registry::getObjectWrapperManager() for access of this object wrapper manager. This
change centralises the singleton management in osgDB.
Merged the osgDB::GlobalLookUpTable functionality into ObjectWrapperManger to keep down the number of singletons in use.
From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg
1. The node type will be set to ATOM on read of <tag prop="..." ... /> type tags.
2. GROUP and NODE are now written using the same code (and not just duplicated code). Also NODE will not be written as an ATOM if it has no children or contents, so you need to set the type to ATOM if you want the <tag ... /> style.
3. You had put the write of "/>" for ATOM after the "return true", so it had no effect... Moved to before the return.
4. ATOM did not write its properties correctly, fixed.
5. As an added bonus, I made the write() method indent the output so it's more readable. It brings a small public interface change but the indent argument has a default value so client code doesn't need to change (if there even is any).
6. Another added bonus, I've simplified the write() method a bit by factoring out the write for children and properties into protected methods."
I have added the missing call to FreeLibrary in osgDB::FileUtils., and now my the runtime unload of MY dll is working properly. It has also cured some related problems I was having with memory leak checks being reported.
I have attached a fix to osgDB/FileUtils.cpp based on version 2.9.5 svn revision 10374
"
filenames starting with a dash "-" character from the (std::vector<std::string>&) version
of osgDB::readNodeFiles. Handling of argument strings is properly implemented in the
osgDB::readNodeFiles(osg::ArgumentParser& arguments,const Options* options)
variant, which most code uses. The (std::vector<std::string>&) version is only called by
the osgconv utility, which does its own argument handling and stripping prior to calling
readNodeFiles().
Also, documented this behaviour in the header comments.
I believe this code removal is a meritful change because leavign the code in causes an
unexpected and undocumented behaviour (ignoring any filename starting with a dash) that
could bite users in the future. This behaviour is not needed for existing functionality
because existing code uses other APIs to handle dash-prefixed arguments anyway.

Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."
Therefore I have changed all the occurances of atof by asciiToFloat or
asciiToDouble.
I believe that it is safe to do so at least for all the plugins.
Included here are also asciiToFloat conversion of environment variables. One
might argue that these should be locale dependent. But IMO these should be
set and interpreted by osg independent of the current locale.

First Submission email from Gustav:
"This submission adds a --cache option to osgconv and osgviewer that enables setObjectCacheHint(osgDB::Options::CACHE_ALL); It greatly reduces memory usage when a .osg file has lots of external references with ProxyNode:s that points to the same file.
Options are also added to the osg plugin. The code was already mostly implemented but there was no way to change the options.
includeExternalReferences
writeExternalReferenceFiles
A counter is added to keep track if an external file has already been written down to avoid writing the same file over and over again. If it has already been written once then it is not written again.
The counter is added to the Output class in osgDB.
"
Second Submission email from Gustav:
"This is a continuation to my previous submission.
I noticed that the same problem that I fixed in ProxyNode.cpp for the osg plugin (external files being written over and over again) also existed in the ive plugin. I attached a submission where the ive plugin remembers which external files that have already been written and do not write them again."
Changes to the above done by Robert Osfield,
changed command line parameter to --enable-object-cache
changed set/get methods in osgDB::Output and ive/DataOutputStream.cpp to be s/getExternalFileWritten(const std::string&)
cleaned up set up of osgDB::Options.
Windows doesn't define F_OK and access() is in io.h, rather than stdio.h
These are fixed in FileUtils.cpp, so I copied the fix from there - might be better to move this to FileUtils header and include it here and in FileUtils.cpp?"
