+% character aligment:
+%
+% Each clef is associated with a particular pitch: the treble clef
+% with the 'g', the alto clef with the 'c', the bass clef with the
+% 'f', etc. The shape of each clef character defines a vertical
+% position that is assumed to represent this pitch. For the treble
+% clef, it is the vertical position of the center of the spiral
+% ending that represents the 'g' pitch. For the bass clef, it is
+% the center between the two fat dots that define the vertical
+% position of the 'f' pitch. For the alto clef, it is the vertical
+% center of the clef that is aligned with the 'c' pitch. For each
+% clef character, this center should be vertically aligned with the
+% point (0, 0). The horizontal alignment of each clef character
+% should be such that the vertical line through the point (0, 0)
+% touches the left-most edge of the clef.
+%
+% TODO: document exact_center
+%
+% set_char_box() conventions:
+%
+% * breapth: Ignored (as far as I know). Should be set to 0.
+%
+% * width: Should match the head's width.
+%
+% * depth: Should match the bottom edge of the head. Affects vertical
+% collision handling.
+%
+% * height: Should match the top edge of the head. Affects vertical
+% collision handling.
