Hmm, have a look at the attached image.  Something doesn't work as
expected...

Is it possible that there is still some vertical space inserted
somewhere?  I tried to set both `padding' and `staff-padding' to zero
(using \tweak), but this has no effect.

In general, it would be great to have a `\scaledMarkup' command which
takes the size of the staff into account to which the markup is
attached.
