and getWorldToLocalMatrix(), computeLocalToWorld() and computeWorldToLocal() methods. Have updated the CullVisitor, IntersectVisitor and Optimizer to use the new osg::Transform::getLocalToWorldMatrix() which has the same functionality as the old getMatrix() but is now supports subclasses of osg::Transform transparently. Have added osg::PositionAttitudeTransform as subclass of osg::Transform which manages the transform as position and attitude via a Vec3 and Quat respectively.
