Since 07d24fe50 regions are not translated to their on-screen
coordinates anymore, but are relative to the origin stored in the
constraint. This origin however was not considered when checking whether
the pointer was within the constraint region. This meant that the
constraint region would appear to always be placed at 0,0 instead of on
the surface.
Fix this by using the cursor position relative to the origin.
Fixes: 07d24fe50 ("backends/native: Allow infinitely small pointer constraint regions")

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.
