The PointerWatcher passes the current pointer position to every watch,
so we don't have to query the pointer again scrollToMousePos() is used
as watch callback.
While that should be the only use, be conservative and still query the
pointer when called without arguments.

These do some some signals connection and monitor layout tracking
that we forget to disconnect when the magnifier is disconnected.
This causes warnings if enabling the magnifier, disabling it,
switching to another tty, and back. (Presumably also happens for
monitor hotplugs).
This signal should just stay connected as long as it's needed,
so add a setEnabled() method on the CrossHairs actor that we
can hook on the magnifier.

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).

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.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/993
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/984
We may get several a11y events setting the caret on the same
coordinates it previously was. Make focus tracking ignore those,
as we're jumping to the same coordinates again during eg. mouse
operation.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/984
It is somewhat unexpected that crosshair color and pointer cursor colors
remain the same across changes in color inversion settings, and may lead
to contrast issues. Apply the effect on the common container, so it
applies to these all.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

The intention of the code is clearly to operate on a copy, but that's
not how the Object constructor works. While it doesn't matter in
practice that we modify the passed-in object parameter, it's still
a good idea to fix the code.

While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.

While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.
Spotted by eslint.

We are currently inconsistent on whether case labels share the same
indentation level as the corresponding switch statement or not. gjs
goes with the default of no additional indentation, so go along with
that.
