If everybody just cares about including PDF (for logos), I'm not sure if we need to implement support for SVG.
I'm not really sure how to get factual data about this (a straw poll on the user list?). In my experience, for things like logos, SVG is more common (there *are* logos in PDF, they're just less common as far as I know, but again this is only my experience).
Another question would be about support in the default PS backend: Is this feasible for SVGs? Would we again export the rendering from Cairo and then paste into the output PS?
Yes, that would be the idea. I don't know another way.
Cross-compilation is always difficult, and what I was trying to say is that the scripts in release/binaries/ currently don't support CMake. Cross-compilation with CMake is sometimes a pain because IIRC it doesn't really support the notion if different targets for host and build, so something like a tools build for execution during the build is not really possible. I don't know about Poppler, maybe it doesn't have any such problems.
I didn't try thus far because I thought SVG would be better anyway, see above.
Rust is actually a pretty big dependency here. How are we going to install this for the build? Especially on CentOS 7, I would be surprised if it can be installed from the distro repository. Would we have to go for the "official" binaries? That's a "meeh" from my side...
Why "meeh"? In my (limited) experience, it is actually most common to install Rust via rustup, because many crates pin their compiler version and some require a nightly compiler, so you can't do with a single globally installed compiler, while rustup arranges so that the version of Rust used in each project is the one specified in Cargo.toml. librsvg requires Rust 1.63, released last August, so whatever the distro version unless very recent, we cannot use the Rust compiler packaged by the distro. But unlike C++, this is considered normal (which is IMHO a relief ...) in the Rust world.
