Version 2.47.1

- Librsvg no longer depends on libcroco!  It now does all CSS
  processing using Rust crates from Mozilla Servo; these are also the
  crates that are in use in recent versions of Firefox.  As a result,
  librsvg can now handle much more complex CSS selectors than before.
  Fixes #79, #167, #237, #283, #336, #428, #441, #466, #525, #525
  (Paolo Borelli, Federico Mena).  Thanks to Evgeniy Reizner
  for fixing https://github.com/servo/servo/issues/22972, which made
  it possible to use Servo's selectors crate.

- #524 - Panic when reading an invalid stylesheet URL in an XML
  processing instruction (Paolo Borelli)

- Lots of little improvements to the documentation.

- Link-time optimization (LTO) is disabled by default on release
  builds, as this increased build time too much.  Downstream
  distributors may want to turn it back on in the toplevel Cargo.toml.

- We now have the start of documentation on the library's internals at
  https://gnome.pages.gitlab.gnome.org/librsvg/doc/rsvg_internals/index.html
  This should be interest of newcomers to librsvg's source code.
