25 % Each clef is associated with a particular pitch: the treble clef
26 % with the `g', the alto clef with the `c', the bass clef with the
27 % `f', etc. The shape of each clef character defines a vertical
28 % position that is assumed to represent this pitch. For the treble
29 % clef, it is the vertical position of the center of the spiral
30 % ending that represents the `g' pitch. For the bass clef, it is
31 % the center between the two fat dots that define the vertical
32 % position of the `f' pitch. For the alto clef, it is the vertical
33 % center of the clef that is aligned with the `c' pitch. For each
34 % clef character, this center should be vertically aligned with the
35 % point (0, 0). The horizontal alignment of each clef character
36 % should be such that the vertical line through the point (0, 0)
37 % touches the left-most edge of the clef.
