your solution works well to keep all TextSpanners baseline-aligned,
but it still does not solve my real problem, which indeed was not
apparent in my first message.
I'm trying to make TextSpanners and tempo markings look the same,
including being aligned at the same baseline.
The reason is to follow the recommendations of Gould for tempo
alteration markings (example at page 184).
A slightly more realistic example follows: I would like to align
\tempo markings and TextSpanners to the same baseline.
As you can see using your trick on both does achieve the desired result.
I renamed the \test function to a more specific \baseline-align.
I'm cc-ing also Harm / Thomas Morley because I'm using his code, so he
may have some insights or suggestions.
Thanks for your help so far.
Best wishes!
Davide
