When manipulating the allocation of a ClutterActor from an allocate() vfunc override, clutter_actor_set_allocation() is used to let Clutter know about the changes. If the actors allocation or its absolute origin did not change before that, this can also affect the actors absolute_origin_changed property used by the children to detect changes to their absolute position. So fix this bug (which luckily didn't seem to affect us so far) and set priv->absolute_origin_changed to TRUE in case the origin changes inside clutter_actor_set_allocation_internal(). Since this function is always called when our allocation changes, we no longer need to update absolute_origin_changed in clutter_actor_allocate() now. Since a change to the absolute origin always affects the resource scale, too, we also need to move that check from clutter_actor_allocate() here to make sure we update the resource scale. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1247 |

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 af 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.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
