#4615 Don't center letter fret labels but align them at their baseline

[Simon Albrecht]

Owner: David Kastrup (dak@gnu.org)

Not sure this change of behavior is really wanted or the chosen value
will be useful/appropriate. This particular change is in
scm/translation-functions.scm. The issue contains another commit that
is independently useful as it stops the redundantly hardwired behavior
established in tab-note-head::print :

Make TabNoteHead.X-offset operative

It has been effectively overridden in tab-note-head::print which
masked the missing default of self-alignment-X.

The regtests clearly show horizontal centering of TabNoteHead not working at all.

Just bother with vertical alignment, horizontal is too messed up

That's pretty much expected: letter tablature uses baseline alignment now. For the half-height letters there, the change is pretty small and appears to work pretty well. The difference is most noticeable with "b" and gamma.
