Yes.  I forgot that we try to keep the number of lines and faces
constant when making the initial frame.  Try the attached patch.  It
should cover everything we have investigated so far.  Unfortunately, it
won't work with an internal tool bar like we have on Lucid, Motif, and
Windows.  There's something I haven't fathomed yet :-(
