The problem appears to be the plot dialog.  It assumes that the line
width setting is in internal units (nano-meters) but I do not think that
is the case.  My guess that the units for linewidth plot setting is
either mils or decimils.  I don't think we ever intended for nanometer
values to be saved in files.  If I knew what units the linewidth setting
is supposed to be, the fix would be easy.  The comment in the header
file doesn't specify the units.
