The OSG has very localised mechanisms for tracking dirty state, such
as in osg::Image and osg::Array, but there isn't a general mechanism,
such a mechanism would be pretty expensive to implement both in terms
of code complexity and CPU cost per frame so it's not something that
has been implemented.
