That's true, and I think it would be easy enough to have a flag to
panel.3dscatter etc. telling it whether the points are already scaled
are not, so that it can rescale itself if necessary. I'll try to get
that in when I have a chance.

Well, in ?panel.3dscatter, the entry for 'x,y,z' says they are

  "appropriately subsetted (using 'subscripts') and scaled (to lie
inside a bounding
  box, usually the [-0.5, 0.5] cube)",

'xlim', 'ylim' etc. are the "limits for the respective axes", and

'xlim.scaled' etc.are "axis limits (after being scaled to the bounding box)".

Not really much else to add (?cloud gives a brief high-level
description of what happens).
