Thanks for the info. Indeed, I used it (the info, and MuPDF) just today
to check if some figures work reasonably well in grayscale.

I've also added this to the pdf viewer wishlist. The one concern I have
about this is that doing it right is far from trivial. As BPJ suggested,
the only "proper" way of doing this is to do proper color management.
This is far beyond the scope for now, so we'd have to settle for some
approximation (which MuPDF most likely does internally, too). But I
guess that should be doable.
