Wayland Protocol Finally Ready For Fractional Scaling

The wp-fractional-scale-v1 protocol allows clients to communicate surface fractional scaling with the compositor. In conjunction with the wp_viewport protocol, it can be used to provide a nice fractional scaling implementation instead of integer-based scaling.

There is already pending code for wlroots/Sway, GNOME Mutter, and KDE to support this fractional scaling protocol. Sample client implementations are also pending for Qt, Rust-based Winit, and others.
