cb8b19939d magnifier: Stop exposing D-Bus interface
Screen magnification is the compositor's business, not that of "random"
unprivileged tools. And for cases where a more specialised behavior is
wanted, an extension likely does a better job than a consumer of the
D-Bus API.

In addition to that, exporting the interface has been broken for an
unknown time, because the object that holds the implementation isn't
referenced and thus ends up being garbage collected, whoops.

And last but not least, this gets rid of the last public D-Bus name
that isn't clearly in the system namespace (org.gnome.Shell,
org.gnome.Mutter, org.gtk).

8a47f1c667 cleanup: Remove empty leading/trailing lines in blocks
gjs added a new rule to its eslint ruleset that forbids "block padding",
so make sure we conform to that rule before syncing up the configuration.

a9a54ba2a3 magnifier: Avoid cursor visibility changes on startup
When initializing the shell, we create the magnifier, and (normally)
let it disabled. This still toggles cursor visibility on, which is
not right since there's other considerations to take during
initialization.

Only do this after actual changes to the magnifier state, so
initialization is left unperturbed.

153b7d525d cleanup: Don't linebreak before closing parentheses
Otherwise recent versions of eslint want "dangling" commas,
which is at least ugly considering that most functions don't
allow adding arguments at leasure.

3848513cf4 magnifier: Use inhibit-unfocus API to keep wayland focus while hidden
Since commit mutter/a2a8f0cda we force the focus surface of the
meta-wayland-pointer to NULL while the pointer is hidden. This
introduced an issue with the magnifier, where we use
`set_pointer_visible` to hide the real cursor and show our own cursor at
the correct position: Because the meta-wayland-pointer is still used to
communicate with Wayland clients, the UI of the windows will not respond
to mouse movement anymore as soon as the real cursor is hidden.

To fix this, use the newly added clutter_seat_inhibit_unfocus() API to
temporarily disable unsetting the focus-surface while the magnifier is
hiding the system cursor.

83d083f189 magnifier: Implement pointer motion tracking differently
The use of the core idle monitor means that focus change events
are also delayed by keyboard interaction. Since the magnifier is
already in the business of pointer tracking, it's easy enough to
fire the pointer rest timeout from here, so focus changes are
accumulated and delayed.

bda18888c0 magnifier: Clip all crosshair lines at even distances
If the crosshair is clipped so it doesn't cover the pointer cursor,
the clip rectangle is skewed towards the bottom/right. This was
made so to accomodate the default pointer, but the unevenness stays
on other pointer cursors, and it makes the crosshair look odd on
short crosshair length.

Make all lines clip to an even distance from the center instead.
