Hi again Till,
Sorry for the delay. #life
As you might have seen, I have finally uploaded 1.11.4-1 with your packaging,
as I didn't want to block on this discussion any further.

ACK. Your business.

That separation is fine, but I want to understand more precisely under which
situations which renderer is used. I seem to remember that under some
circumstances, ghostscript would be preferred over poppler, or the inverse; I
can't recall out the precise details right now.
So… Are these three entirely interchangeable, and would provide the same
experience across the whole printers' ecosystem, or does one need (e.g.)
ghostscript for Epson printers, and poppler for HP printers ?
I don't want to worsen the experience by removing one of these renderers,
especially not shortly before Debian's freeze.

I need a better understanding of the "surface coverage" of the various
renderers before ironing out a plan.
