I’ve always been unhappy with the current method for whiteout (which I
have also been using in rounded-box-stencil, nevertheless). LilyPond
scores’ background is _not_ white, but alpha transparent. Look for
example at the way Frescobaldi displays PDF scores by default, or at the
picture attached to

So, ideally \whiteout should mimic this behavior rather than cover stuff
with a layer of white paint. Not sure how to do that, though.
