OpenSceneGraph/include/OpenThreads/ScopedLock
Robert Osfield 323ce02f23 Moved OpenThreads directly into OpenSceneGraph/trunk rather than being introduced via svn:externals.
This change has been done to make it easier for OpenSceneGraph users to check out the svn via https 
without any conflicts introduced with a http externals.
