+%% FIXME
+% There is a problem with noteheads slightly extending beyond the staff
+% lines. This is due to the fact that staff_space + stafflinethickness
+% is sometimes an odd number, so the nothead height and depth are not
+% integers. Then, when the font is converted to an outline font, the
+% system rounds up the 0.5 left over from dividing the notehead height
+% in two, and the notehead extends slightly beyond the staff line.
+% In order to resolve this problem, we use overdone_heads to slightly
+% reduce the notehead height. Empirically, we have determined that
+% reducing by 10% of stafflinethickness solves the problem.
