Change the osg::NodeVisitor::getLocalToWorldMatrix() /
getWorldToLocalMatrix() methods so it do not initilize the matrix being
passed to them, and assume the the users has already initiliazed them
appropriately, such as to take account of camera positions.

================================================ ================================================
2nd February 2002 - osg-0.8.44.tar.gz
>>> Support added for Mac OSX, Cygwin and MinGW, and new TerraPage loader.
The major item for this release is the completion of the Mac OSX port,
thanks to Phil Atkin and others for making this happen.
Also added to support for Cygwin and MinGW builds which gives Windows
users a free and robust alternative to the Visual C++, which we
have Norman Vine to thank.
Funtionality wise there has been a great deal of work behind the scenes
putting in place a flexible and extensible framework for handling
transform nodes, users can now extend the osg::Transform node through
subclassing or via callbacks. This work will underpin future work
on moving camera setup into the scene graph, and environmental effects
such as cloud layers, ground planes, stars and earth sky implementations
which are planned for the next release.
Callbacks and virtual methods have also been added to the osg::LOD &
osg::Billboard to allow users to customize their behavior. Draw
callbacks have also been added to allow customization of osg::Drawables
at runtime.
The Open Flight .flt loader has undergone a number of improvements
including support for instancing and billboards.
Support for the clone operation on osg::Object's has been expanded
to allow cloneType() - a simple clone an blank object of the same type,
and clone(CopyOp&) where CopyOp is a functor which allows users to
specify the deep copy vs shallow copying of object data.
