I saw you interrogating SlurStub regarding its purity, but did not
notice that SlurStub took any different shape based on 'pure' estimates.

The SlurStubs in the regtest were shaped just like the printed Slurs,
but now I see the difference in the Chopin prelude, with

 \layout { \context { \Score
   \override SlurStub #'color = #green
   \override SlurStub #'transparent = ##f
   \override Slur #'color = #darkgreen
   \override PhrasingSlur #'color = #darkgreen }}

The SlurStubs are not sufficiently accurate to help, and they cost me
time.
