A transaction contains the committed state for a surface, plus any cached state for synchronized subsurfaces. v2: * Handle sub-surface positions separately from surface states. v3: * Sync child states only for surfaces with state in the transaction. v4: (Jonas Ådahl) * Drop unnecessary g_object_new call from wl_subsurface_set_desync. (me) * Fix indentation & formatting in meta_wayland_surface_commit. * Add meta_wayland_surface_state_new helper function. * Fix alignment of meta_wayland_transaction_apply_subsurface_position parameters. * Add curly braces around meta_wayland_transaction_sync_child_states call in meta_wayland_transaction_apply. v5: * Make meta_wayland_surface_state_new an inline function.

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
