 * Implementations of this strategy compute bezier curves
 * for curved lines, given the absolute coordinates of
 * the noteheads of the chords connected by the curved line.
 * 
 * All coordinates must be given in line positions, even
 * the horizontal ones. If the curved line spans over more
 * than a single staff, the line positions of the other staves
 * must be expressed as line positions of the staff the first
 * chord belongs to.
