In order to allow a window with a custom rule placement to be moved together with its parent, the final rule used derived from the constraining were used for subsequent constraints. This was not enough as some constraining cannot be translated into a rule, such as sliding across some axis. Instead, make it a bit simpler and just remember the position relative to the parent window, and use that the next time. This is a rework of 5376c31a33020d7dc5a69b129f2dd4f42d0890a1 which caused the unwanted side effects. Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/332
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.
