No need to reinvent the wheel.
Yep. Using make-path-stencil is much more straight-forward. Thanks. If someone interested, I'll attach an image with an excerpt of my test-suite. I plan to replace make-parenthesis-stencil and to implement https://sourceforge.net/p/testlilyissues/issues/3088/ > > While this particular wheel could likely profit from a do-over with more > of a view towards efficiency and numerical robustness, there is no point > in code duplication. I think we could replace the body of current make-bezier-sandwich-stencil with make-path-stencil. But obviously you think about some deeper modification. Could you give some details? Cheers, Harm
