Dor Askayo 7eb99ddef7 wayland/surface: Schedule updates in the context of the surface actor 
This makes all stage updates that result from applying the pending
state of a Wayland surface emit an "update-scheduled" signal in the
context of the relevant surface actor.

A common case where an "update-scheduled" signal is needed is
when applying "empty" client commits. In this case a
"repaint-scheduled" signal would not be emitted since the commit
doesn't trigger a repaint. However, it is still important to add
handling for such updates with variable refresh rate when the
releavnt actor is also driving the refresh rate.

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.
