Carlos Garnacho 54e4d1df79 x11: Defer ClutterStage focus actor change until window is focused 
If we happen to be changing focus to a window *while* taking focus
away from Clutter widgetry, we would unintendedly trigger reentrance
in a way that the old focused window remained in focus, by asking
to focus the default focus window in an untimely manner.

To handle this reentrancy, delay dropping the Clutter key focus
until the window focus changed, so that the focus change will look
up the default focused window in the workspace, and find the up to
date one.

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.
