Olivier Fourdan 7ab3eac0e2 constraints: Use "orig" rectangle for interactive resize 
Bug 448183 fixed an issue with _NET_WM_MOVERESIZE_WINDOW not moving a
window by basing the resize on the current (new) rectangle instead of
the original rectangle.

While this fixes the issue with _NET_WM_MOVERESIZE_WINDOW, this also
causes windows with a size increment to move when the resize also
implies a move, such windows might drift while resizing.

Make sure to use the current rectangle for non-interactive resizes only.

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.
