+% 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.
