Objective

• Fix Wayland window client side decorations issue on Gnome Wayland, fixes Bevy wayland window name is "Unknown" #3301.

Solution

• One simple one line solution: Add winit's wayland-csd-adwaita feature to Bevy's wayland feature.

Copied from #3301 (comment):

Investigation

1. Gnome forced Wayland apps to implement CSD, whether on their own or using some libraries like Gnome's official solution libdecor. Many Linux apps do this with libdecor, like blender, kitty... I think it's not comfortable for Bevy to fix this problem this way.
2. Winit has support for CSD on wayland(https://github.com/rust-windowing/winit/blob/8bb004a1d9ec1b40cbb9831a6dea774d4b6d6d7b/Cargo.toml#L42), but Bevy disabled Winit's default features, thus no winit's wayland-csd-adwaita feature. And Bevy's wayland feature doesn't include winit's wayland-csd-adwaita feature so users can't get window decorations on Wayland even with Bevy's wayland feature enabled.
3. Many rust UI toolkit, like iced, doesn't disable winit's wayland-csd-adwaita feature.

Conclusion and one Possible solution

Bevy disabled winit's default features in order to decrease package size. But I think it's acceptable to add winit's wayland-csd-adwaita feature to Bevy's wayland feature gate to fix this issue easily for this only add on crate: sctk-adwaita.

With this patch, the 3d_scene example looks like this on Gnome Wayland (with native window decorations):
