Frankly, I have no idea what I am actually doing there with the
ly:stencil-aligned-to .  I was just fudging around until something fell
out that looked like what you wanted to be doing.  So "\squashed" is
actually a misnomer from the first attempt where I just thought I'd
shrink stuff (which did not work).

So while the technique for diddling with a stencil is programmed in a
straightforward manner, I have no clue about the underlying core action.
