And another question: in the cases where you see artifacts, does the
call to font-shape-gstring inside compose-gstring-for-graphic return
nil or non-nil? IOW, is the shaper+font producing the composed glyph,
or is that the fallback Lisp code in compose-gstring-for-graphic,
because font-shape-gstring returns nil? Perhaps that's the reason for
the differences between what you see and what I see.
