Comment #5 on issue 1854 by address@hidden: Add some polyphonically  
directed grobs
http://code.google.com/p/lilypond/issues/detail?id=1854

I need some help. I wanted to make two glyphs for each type of note longer  
than a whole: one with a small and one with a large hole.
(As you can see in facsimile.png attached to the third comment, the 3rd  
note has a smaller hole than the 5th)

This works great, but I can't manage to do this for every note style. I  
reach the maximum number of characters per font group. What shall I do?  
Separate styles into several font groups and files? I saw in several mf  
files some "begingroup" inside definitions. Is this what should be done?

Thanks,
Bertrand
