If the @code{padding} property of an object is increased when that
object is in a stack of objects being positioned according to
to simulate a fermata in the MIDI output we would not want the
metronome markings to appear in the printed output, and we would
not want it to influence the spacing between the two systems or
-the spacing of the notes on the staff. So setting its
-@code{stencil} property to @code{#f} would be the best way.

We show here the effect of the two methods:

-Both methods remove the metronome mark from the printed output,
-and both affect the MIDI timing as required, but the first
-(transparent) metronome mark still influences the note spacing
-while the second (with no stencil) does not.
