We send configure events for state changes e.g. for `appears-focused`, etc. What we don't want to do is to do this for popup windows, as in Wayland don't care about this state. When the focus mode was configured to "sloppy focus" we'd get `appears-focused` state changes for the popup window only by moving the mouse cursor around, and while a popup may care about focus, it does not care about related appearance, as there is no such state in xdg_popup. What these state changes instead resulted in was absolute window configuration events, intended for toplevel (xdg_toplevel) windows. In the end this caused the popup to be positioned aginst at (0, 0) of the parent window, as the assumptions when the configuration of the popup was acknowledged is that it had received a relative position window configuration. Fix this by simply ignoring any state changes of the window if it is a popup, meaning we won't send any configuration events intended for toplevels for state changes. Currently we don't have any way to know this other than checking whether it has a placement rule. Cleaning up MetaWindow creation is left to be dealt with another day.

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.

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.
