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.
completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."

memory manager published at flipcode.com. This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.
Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.

only be called in special circumstances, the ReaderWriter::ReadResult

being multiple referenced on return from readNodeFile() & readImageFile().

for settings options in osgDB::Registry, and added the paramter to all of the
reaader/writer plugins. The Options structure by default has an string attached
for packing basic options, however, it also can be subclassed to encapsulate
any users defined option data. In the later case both the client code *and*
the plugin need to be aware of subclass, the plugin will need to use
dynamic_cast<> to assertain its type.
