Created a new GraphicsThread subclass from OperationThread which allows the
GraphicsContext specific calls to be moved out of the base OperationThread class.
Updated the rest of the OSG to respect these changes.
Added and cleaned up DeleteHandler calls in osgViewer to help avoid crashes on exit.
Changed DatabasePager across to dynamically checcking osg::getCompileContext(..)
Updated wrappers.
according to the OpenSceneGraph/CMakeLists.txt and the include/osg/Version settings.
These changes mean that the 1.9.5 release will have a libs/osgPlugins-1.9.5 directory.
"By repurpose, I'm creating a new plugin that uses much of the .osg fileformat,
but with some changes. Specifically, I'm creating a ".osgfs" plugin, which
represents the scenegraph hierarchy as a filesystem of nested subdirectories and
individual files for each node, rather than nested braces with everything in a
single monolithic file. I intend to incorporate file alteration monitor events
to watch the filesystem for modifications and automatically reload.
The problem I'm running into is osgDB is too tightly coupled to the .osg format.
osgDB::Output::writeObject() contains literal .osg format-specific strings like
"{" to represent the Object hierarchy at too low a semantic level. I propose
using virtual methods; my plugin can then derive from osgDB::Output and
represent Object hiearchy differently.

~~~~~~~~~~~~~~~~~~~~~~~~~
This is a simple change to permit databases other than those named
"*.osga" to be used. It is hardcoded in read() at present.
It is non-critical and does not affect existing program functionality.
Registry and Registry.cpp
~~~~~~~~~~~~~~~~~~~~~~~~~
Added a new typedef: typedef std::vector< std::string>
ArchiveExtensionList;
a list of extensions: ArchiveExtensionList _archiveExtList;
and an "add" method: addArchiveExtension(const std::string ext)
This is initialised by adding "osga" in Registry() and used in
Registry::read() where the list is searched for the extension used.
Archive.cpp
~~~~~~~~~~~
This submission is a little more tentative. openArchive() is modified to
automatically add the filename extension to the Registry extension list.
"
so I' ve set up a macro that uses the variable name expanded for linking, and test if a variable ${LINK_VAR_NAME}_DEBUG
like OPENTHREADS_LIBRARY_DEBUG exists and in case uses it for linking in debug mode.
I' ve also set up FindOpenThreads to set up these variables.
I had to edit the core libraries CMakeLists to add the calls to the macros used.
I' ve tested under MSVC"
To set up extension aliases using a config file, an app calls:
osgDB::Registry::instance()->readPluginAliasConfigurationFile(), passing in the file name as the parameter. (Of course this should be done before loading any files whose names depend on the mapping.) osgDB will search for the file using OSG_FILE_PATH.
The file should contain a line for each mapping, with the "map" extension first, followed by a space or tab, then the plugin identifier. For example, a file containing this line:
flt OpenFlight
would map the ".flt" extension to the OpenFlight plugin."

default Registry Options object, but it would be useful to be able to
request loading with a different Options object. The attached files
allow you to do that (based off the OSG 1.2 source).
For example, I'm implementing a loader that requires context information
when it pages in subgraphs, which becomes significantly complicated when
multiple scenegraphs are requesting subgraph loads with different
contexts (the loader needs to know which context to use, and the
Registry Options needs to be carefully managed so the context settings
don't clobber each other, especially in multithreaded situations). Being
able to pass an Options instance along with the Node request resolves
this problem."
Fixed bug osgDB::Registry::Registry::read(const ReadFunctor& readFunctor) relating to
the handling of failed loads with the ReadResult::_message value being lost, this changes
ensure that the original ReadResult from the plugin, with message intact, is returned correctly.
