persp3d supports a zlim argument to set the bounding box, but it doesn't 
make sense to ask rgl.surface to do that.  It's a low level function to 
add a surface to a scene, it knows nothing about the scene as a whole.

I don't recommend mixing rgl.* functions with *3d functions, either: 
you will get weird things happening (disappearing text, strange colours).
