Zack Rusin 27f798b6d0 kms/impl-device/atomic: Implement mouse cursor hotspots
DRM's kms atomic code was updated to include an API to set the mouse
cursor hotspot. This has historically been missing in the atomic kms
which meant that the virtualized drivers which require mouse cursor
hotspot info to properly render had to be put on a deny list and
had to fallback to the legacy DRM kms code.

Implement the new hotspot API by checking whether the device supports
hotspot properties and if it does set them on the cursor plane. This
enables atomic kms on all virtualized drivers for kernels where
mouse cursor hotspots are in drm core.

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.
