I took a brief look at the manual
(https://cairographics.org/manual/cairo-surfaces.html), it appears it
does exposes them.

The other reason I left them in propagated inputs is because, the
packages that depend on cairo doesn't build without them. If I
de-propagate them in cairo, then I have to replicate them as inputs on
other packages.

Hmm. Without that, I get "package not found" while doing `./pre-inst-env
guix build foo`.

Thanks!
