Librsvg 2.45.3 is out!

This is the first release where all the real work of the library is done in . The public API, still in C, is mostly just an empty shell now that immediately calls into Rust. I don't want to chant "WE DID IT" just yet, but I kind of want to, you know?

Special thanks to Paolo Borelli for making this possible.

Next step: actually implementing the GObject boilerplate in Rust.
