Looking more closely at this page, I don't fully understand how it
works.  It is stated that the unpure-pure stuff affects y-axis
calculations, but the given example adjusts the *width*:

  In the first measure, without the unpure-pure container, the spacing
  engine does not know the width of the note head [...]

How comes?  I think this deserves some more explanation.
