Ah, you need to adjust the vertical extent in the other direction:

%%%%
\markup \with-dimensions #'(0 . 0) #'(2.5 . 0)
  \general-align #Y #UP "foo"
%%%%

The vertical extents #'(0 . -2.5) and #'(2.5 . 0) both have the same 
effective height of -2.5 units, however they have a different relative 
starting point which is important for what may appear *below* the 
markup.  In my example, I needed the red rectangle to snugly fit with 
the scores on both sides, so I apologize that it was not very clear how 
the vertical extent had been altered to achieve that.

Also, do use \general-align to avoid futzing with \vspace in your 
markup.
