Sebastian Keller f10b3eac62 frames: Always initialize _MUTTER_FRAME_EXTENTS to zero 
The frame size_allocate() will set it correctly once show() is called by
the window tracker.

This is less code and also help reduces the chance of a brief visual
glitch in fullscreen games during startup. If the window is initially
still decorated the gray area would still show up until the next redraw,
which due to loading times can take a while.

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.
