With Wayland, a window is not showing until it's shown. Until this patch, the initial state of MetaWindow, on the other hand, was that a window is initialized as showing. This means that for a window to actually be classified as shown (MetaWindow::hidden set to FALSE), something would first have to hide it. Normally, this wasn't an issue, as normally we'd first create a window, determine it shouldn't be visible (due to missing buffer), hide it before the next paint, then eventually show it. This doesn't work if mutter isn't drawing any frames at the moment (e.g. the user switched VT), as we'd miss the hiding before showing as e result of a buffer being attached. The most visible side effect is that a window can't be moved as the window actor remains frozen. This commit fixes this issue by correctly classifying a newly created Wayland window as "hidden".

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 GNOME Shell, the GNOME core user interface. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
