Thanks.  However, it seems not to be as 'open source' as advertised:
The file

  https://gitlab.com/vgg/image-compare/-/blob/main/app/js/transform.js

mostly consists of a huge binary WASM blob, without any hints where
this comes from and what it does...

Anyway, AFAICS, it doesn't provide what we need for LilyPond.
