Hi,

(back from holidays)
We've already ly:stencil-aligned-to and centered-stencil, leading to:

circle = #(make-circle-stencil 3 0.4 #f)

square =
#(stencil-with-color
  (make-connected-path-stencil
   '((0 0) (3 0) (3 3) (0 3) (0 0))
   0.4 1 1 #f #f)
  blue)

\markup \line {
  \stencil #(ly:stencil-add circle square)
  "   "
  \stencil #(ly:stencil-add circle (ly:stencil-aligned-to square X CENTER))
  "   "
  \stencil #(ly:stencil-add circle (ly:stencil-aligned-to square Y CENTER))
  "   "
  \stencil #(ly:stencil-add circle (centered-stencil square))
}

So I see no advantage in a new LSR-snippet.


Cheers,
