Robert Mader 192d6686cf backend/cogl-utils: Move, rename to cogl-drm-formats and clean up
1. Move into the new 'common' folder and build for Wayland as well
   so we will be able to share the code in follow-up commits.

2. Rename to cogl-drm-formats to make it more obvious that the format
   map is more than an utility these days.

3. Drop the unused CoglTextureComponents part (see also previous
   commit).

4. Move the map to the header, simplifying some future use-cases.

5. Sync formats with MetaWaylandBuffer and MetaWaylandDmaBufBuffer and
   also use newly introduced opaque formats where appropriate.
   This avoids duplicated code, ensures that new drm-formats added to
   the dmabuf protocol have an adequate representation in Cogl from which
   information like alpha support can be easily derived and finally
   ensures we don't crash if the mappings got out of sync.

6. Remove some likely untested formats. In case some of these are
   actually needed on certain hardware, we can test whether we got
   the correct mapping by also adding support for the corresponding
   wl_shm_format in MetaWaylandBuffer by extending the gradient test in
   https://gitlab.freedesktop.org/jadahl/wayland-test-clients

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.

Contributing

To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.

It can be useful to look at the documentation available at the Wiki.

See HACKING.md.

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.

If a commit fixes an issue and that issue should be closed, add URL to it in the bottom of the commit message and prefix with Closes:.

Do not add any Part-of: line, as that will be handled automatically when merging.

The Fixes tag

If a commit fixes a regression caused by a particular commit, it can be marked with the Fixes: tag. To produce such a tag, use

git show -s --pretty='format:Fixes: %h (\"%s\")' <COMMIT>

or create an alias

git config --global alias.fixes "show -s --pretty='format:Fixes: %h (\"%s\")'"

and then use

git fixes <COMMIT>

Example

compositor: Also consider dark matter when calculating paint volume

Ignoring dark matter when calculating the paint volume missed the case where
compositing happens in complete vacuum.

Fixes: 123abc123ab ("compositor: Calculate paint volume ourselves")
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1234

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
