Do you remember what version it last worked with?

It looks like there was some kind of mixup adding info about cairo to
the changes doc. I can see the doc code in this diff:
https://gitlab.com/lilypond/lilypond/-/merge_requests/1651/diffs?commit_id=1df07dd726ff8bf16e60501080fcbd47b82ae6d4
but it looks like that merge request somehow didn't end up including
that. I'll see about preparing a patch for it.

To summarise what's there: it should be an improvement over ghostscript,
but it's still experimental and doesn't implement all of the features of
the other backends (I can't remember what, if anything, is missing).
