But again, that would be overloading the functionality of the Separator
node. It would be better to have an Annotation node which, like the
Separator, is a group node with the behavior that its children all face
the camera. As Gavin has stated, we really need to consider 3 issues when
we discuss annotation: depth buffer (do annotations appear on top of
everything?), object size (do objects stay the same size as you move
closer?), and orientation (do objects always face the camera?).
