 * in {@link MeasureElementsSpacer}.
 * <pre>

 * beat:     0   2   4   6   8

 * voice 1:   o      2
 * voice 2:    1          o
 * </pre>
 * Between VE1 and VE2, there are 6 spaces.
 * Assuming a padding width of 1 and a clef width of 6,
 * the clef can be moved two spaces to the left, but this is not
 * enough. All elements at or after beat 3 have to be moved 2 spaces
