It's worth noting that something like this may work in a minimal example
and fail when it occurs 20 measures into the score since LilyPond keeps
track of the current time as a fraction too, and if p/q fits its sizes,
that does not mean that p/q+80 (or whatever) will also fit.

So it's quite possible to "demonstrate" that something works when it is
not actually usable in practice.

Of course the Photoshop accusation is pure delusion: who'd go to that
kind of work for that kind of gain?

But there are also ways to "photoshop" in LilyPond and generate visuals
that do not actually correspond to LilyPond's own idea of the music.
And those, cast into music functions, might be the best path towards
getting such stuff reliably typeset until LilyPond's precision catches
up.
