Duh, why didn't I remember the -10 thing.  Anyway, I tried that, and it  
does indeed work!  The font sizes are very similar in size on Windows  
and Mac OS X.  But now the problem is that the boxes on Mac OS X a  
being created too large.  I think that this shouldn't be too hard to  
figure out, it might just be a matter of replacing all of the Xwindows  
font specs with { courier -12 bold } Tk-style font specs.

It would be great to get this into the upcoming Pd-extended release.
