I have just checked a change to Group::computeBound() so that is uses a Drawable::getBoundingBox() when a child is a Drawable. This should mean that the Geode containing Drawables, or a Group containing Drawables will have the same bounding volume and hence culling effectiveness. To support this change I also added a Node::asDrawable() and Node::asGeometry() to provide a low cost way of casting to Drawable and Geometry.
