-% Notes about 8th rest:
-%
-% * 8th rest should be no wider than the black note head
-%
-% * The inside corner of the horizontal portion is usually a little blotted.
-%
-% * The top of the crook chops off the vertical brush
-%
-% * The crook widens a little
-%
-% * The bottom of the brush is slightly flat, as it has to align with
-% stafflines if it is inside the staff.
-%
-% * The top of the brush usually is a little lower than the top of bulb.
-%
-% * The bulb can vary. Sometimes it is open (like in the clefs). Sometimes
-% it is closed, or even a flare.
-%
-
-% from an email to Rune Zedeler:
-%
-%
-% For example, the 8th rest was vaguely based on a book with trumpet
-% studies by Duhem, and by Baerenreiters cello suites. I included my
-% findings in a comment in the mf file. One of the things that I tried
-% to do was make the rest a little lighter and narrower than the black
-% note head. I think this looks better in polyphonic music, when the
-% rest is below a head from a different voice.
