Comment:

 The patch prevents the above error, all doctests pass.

 JMOL doesn't like the resulting file; it gives errors about #faces must be
 positive, or something.  My vote would be to fix that error when we try to
 create the JMOL-formatted file.  (We could raise an error here, but then
 sum([implicit_plot3d(...) for i in range(10)]) might break unnecessarily.)
