This means objects have an owner, where the chain eventually always leads to a MetaContext. This also means that all objects can find their way to other object instances via the chain, instead of scattered global singletons. This is a squashed commit originally containing the following: cursor-tracker: Don't get backend from singleton idle-manager: Don't get backend from singleton input-device: Pass pointer to backend during construction The backend is needed during construction to get the wacom database. input-mapper: Pass backend when constructing monitor: Don't get backend from singleton monitor-manager: Get backend directly from monitor manager remote: Get backend from manager class For the remote desktop and screen cast implementations, replace getting the backend from singletons with getting it via the manager classes. launcher: Pass backend during construction device-pool: Pass backend during construction Instead of passing the (maybe null) launcher, pass the backend, and get the launcher from there. That way we always have a way to some known context from the device pool. drm-buffer/gbm: Get backend via device pool cursor-renderer: Get backend directly from renderer input-device: Get backend getter input-settings: Add backend construct property and getter input-settings/x11: Don't get backend from singleton renderer: Get backend from renderer itself seat-impl: Add backend getter seat/native: Get backend from instance struct stage-impl: Get backend from stage impl itself x11/xkb-a11y: Don't get backend from singleton backend/x11/nested: Don't get Wayland compositor from singleton crtc: Add backend property Adding a link to the GPU isn't enough; the virtual CRTCs of virtual monitors doesn't have one. cursor-tracker: Don't get display from singleton remote: Don't get display from singleton seat: Don't get display from singleton backend/x11: Don't get display from singleton Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2718> |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor: or
clutter/actor:, and it's always better to write too much in the commit
message body than too little.
Default branch
The default development branch is main. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
