LM 4.4.2 \fooDown \fooUp (and how about \textDown?)

[Valentin Villenave]

Greetings everybody, hi Trevor,

I've been looking at the LM 4.4.2 Placement of objects > Within-staff
objects, and I'm not sure we want to use "Down/Left" and "Up/Right" in
the table. Yes, we all know that -1 and 1 may respectively mean either
"down" or "left" and either "up" or "right", but in this table we're
*only* documenting objects that are aligned vertically!

Oh, and by the way: we have \textSpannerDown for text spanners, but
not \textDown for simple TextScript objects (that are quite likely to
be needed by new users). Anyone against adding textDown, textUp,
textNeutral?

Cheers,
Valentin.
