Olivier Fourdan 7dbb4bc3f5 window-actor/x11: Cache the client area
With Xwayland, the shape region is recomputed and reapplied even when
the actor is frozen to prevent the black shadows effect.

However, while recomputing the shape region, the current client size is
taken into account, rather than the size when the client was frozen,
which is ahead of the actual client size using the NET_WM_SYNC protocol.

Keep the current client area and to reuse them when the X11 window actor
is frozen for rebuilding the client mask texture.

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.

Contributing

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

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.
