Have made osg::Transform more extensible via additions of new getLocalToWorldMatrix() 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.

using namespace osg;

}
Have taken a few more steps towards support for view dependant transformations by adding a ComputeTransformCallback to osg::Transform, and have now removed the recently added AutoTransform since it is nolonger required. Have also updated CullVisitor to account for the new ways for tracking transformation matrices in the scene.

Added DataVariance enum and set/get fields to osg::Object to help identify which objects have values that vary over the lifetime of the object (DYNAMIC) and ones that do not vary (STATIC). Removed the equivalent code in osg::Transform, StateSet and StateAttribute, as these are now encompassed by the new DataVariance field. Removed MatrixMode enum from Matrix, and associated fields/parameters from osg::Transfrom and osg::NodeVisitor, since MatrixMode was not providing any useful functionality, but made the interface more complex (MatrixMode was an experimental API) Added ReferenceFrame field to osg::Transform which allows users to specify transforms that are relative to their parents (the default, and previous behavior) or absolute reference frame, which can be used for HUD's, camera relative light sources etc etc. Note, the view frustum culling for absolute Transform are disabled, and all their parents up to the root are also automatically have view frustum culling disabled. However, once passed an absolute Transform node culling will return to its default state of on, so you can still cull underneath an absolute transform, its only the culling above which is disabled.

Made improvements to osg::AnimationPath, added osg::PositionAttitudeTransform::AnimationPathCallback which us an app callback which uses an AnimationPath to specify the new positions of the transform. Added AnimationPath code to osglight to animate the positional light. Added CullVisitor::setCullingMode() code into SceneView so that SceneView's CullingMode is now properly passed onto CullVisitor. Note, this work had been done before, but must has been lost in a merge. Umm...
