OpenSceneGraph/doc/doc++/osg/FrameStamp.html
Don BURNS ac2bdbda30 1) new implementation of the osg::Matrix class. Note details below. 
2) cleaned up osg::Timer, still in progress.  My intent has been to
     pave the way for support for other OS's.
  3) new osg::FrameStamp class which has a frame number, reference
     time for each frame to be app, culled and drawn.  The FrameStamp
     also can be passed to other machines (i.e. cluster) and the
     FrameStamp can be used with the slaves own app,cull and draw.
     I've also added the beginings of a calander time data to the
     FrameStamp to allow time or day and year to be used in setting
     up position of sun/moon etc. etc.
  4) The osg::State now has contains a pointer to the last applied
     osg::Camera and the current osg::FrameStamp, so that drawables
     can use both pieces of information for creating effects such
     CLOD, earth/sky etc.  The osg::NodeVisitor also now allows you
     to attach a FrameStamp to support syncronization of actions on
     the scene graph.
