:-) That seems like a reasonable suggestion... I had been copy-pasting
and adapting my code.

Wow, that looks good! I could adapt this to my circumstances, and it
seems to do exactly what I want! Hans: could something like this be
added to the core? The keywords "max fit broad" for the "factor"
option are already taken, so what about "fill"? But I guess it only
makes sense if we can test and adapt to the current vbox (not
necessarily the page).
Anyway: Wolfgang, thanks a lot, this does exactly what I want!
All best
Thomas
