Re: feature requests: scalable \shape values; (stem) for \shapeII

Hello Jean,

thanks for further exploring the first request. In my experience with Lilypond 2.20 \shape doesn’t scale with set-global-staff-size either. I’m already kinda “used” to writing smaller values —my primitive math only cooperated with me today to figure that I can use fractions to easily scale numbers when I use a smaller font (with set or magnify), but I realized it’s not only cumbersome but also a great property like the (head) mode in \shapeII can’t take advantage of proper scaling to do its job well, which is a pity. With ‘set’ it might also be that it works sometimes and sometimes not. I’m pretty sure it doesn’t reliably scale anyways.

Thank you for opening that issue!

Could you show an example? The images were created using LilyPond 2.19.83 on the following examples:

\version "2.19.83"
{ c'1-\shape #'((0 . 0) (0 . 10) (0 . -10) (0 . 0)) ~ c' }

\version "2.19.83"
#(set-global-staff-size 10)
{ c'1-\shape #'((0 . 0) (0 . 10) (0 . -10) (0 . 0)) ~ c' }

As you can see, the tie does scale properly, compared to the use of layout-set-staff-size:

The same happens with a recent build.

Best,
Jean
