    - IO/Plug-in support
        . improve the ascii parsing class osg::Field, osg::FieldReader etc.
        . change the osg::Registry to timestamp registrations of objects/RW's.
        . add support for file path logging into osg::Input.
        . add binary data reading and writing into osg::Input/osg::Output to
          support part binary .osg files.

o Work completed
  ==============
    - osg namespace implemented.
    - reduce the STL platform specific #ifdef's.
    - remove using namespace from all header files, so not to pollute user space.

      instead of the plug-in functions found in sg.cxx.  
    - add support for removal of plug-ins from osg::Registry,
    - add .osg support into DCS node.
    - clean up inheritance relationship between osg::Node, osg::Object etc.
    - add osg::Switch for handling optional rendering of children.
    - add osg::LOD (level of detail) group node for load management. 
    - add view frustrum culling into osg::RenderVisitor.
    - add support for mutliply referenced nodes into osg::Input.
    - add a quaternion class.
    - improve osg::BoundingBox and osg::BoundingSphere.
    - add hit and intersect classes for collision detection.
    - add intersect visitor.

    - document how to get the OSG compiled and running under all
      platforms, Win32 being priority as it's the least obvious.
    - .gz (as osgtgz and .tgz) Automatic unzipping of GNU zipped files.
    - .zip      Automatic unzipping of windows zipped files.
    - add osg::State for mainting image of the OpenGL state.
    - improve osg::GeoState -> improved version call osg::StateSet.
    - create a base class to provide interface to objects which can render,
      derive osg::GeoSet from this.
    - add support for multi-pass rendering.
