a curious workaround for flabby rounded-boxes

[Robin Bannister]

Hallo there


I was looking to revamp my DIY fingering functions in the light of 
features available when moving from 2.18 to 2.20,  e.g. I can get 
tighter positioning via TextScript.parent-alignment-X.

There is a 'ringed' function for fingerings which need highlighting. 
Its bulbous \circle now seems rather wasteful of width, so I thought I 
could try \rounded-box instead.  Well, it could certainly made be 
narrower and still readable, but it has spurious padding which wastes 
width too.

This padding bug was found a year ago
http://lists.gnu.org/archive/html/bug-lilypond/2018-03/msg00022.html
and it should be gone by 2.21.0.
https://sourceforge.net/p/testlilyissues/issues/5307/



My workaround involved using \with-dimensions-from to apply the extents 
of a throwaway corner-radius_0 version to the wanted rounded version.
This was ugly but effective.
Today I inadvertently changed that 0 to 1 and it still worked!


So here is a compact workaround - attached, as \rounded-boxx.


It uses the rounded version to correctly crop itself.
This is beyond the extent of my explanatory powers.
Note that \pad-x 0 is ineffective, presumably because it sets the 
extents in a different way.


Cheers,
Robin
