OK, thanks.

Nope, this doesn't work, AFAICS.  I have a paper setting

```
\once \set markup-system-spacing.padding = 2.5
```

and my code uses

```
\markup \with-dimensions #'(0 . 0) #'(0 . 0) {
  ...
}

\score { ... }
```

and there is apparently no way to make the markup really
'transparent', i.e., taking zero vertical space.  The padding between
markup and system is always inserted, and I wasn't able to find a
solution to give the markup a 'negative height'.
