I think I found a bug in freewrl in the Billboard
node. If the axis of rotation is 0 0 0 then the
billboard should always face the user. In the attached
code, the axis labels always rotate around the axis.
However, the funny Billboard rotates correctly. I
think what is happening is that the transform rotation
is leaking into the billboard rotation, and I don't
think that is the desired behavior. "
