The same code for reading the current magnifier state is repeated in both
shell-recorder, shell-screenshot and magnifier itself.
So to move this inside a property of st-settings so that we can refer to it
all over the places removing duplications.

There's no point in keeping the cursor sprite texture around all the time,
and to listen for its changes, we just need this when the magnifier is active.
So, initialize the magnifier texture and monitor for the sprite changes on
activation, while disconnect from the signal and nullify the texture when
the magnifier is deactivated.

In order to paint all the color channels of the content texture we need to
set the color channels to 255, so instead of doing this manually we can just
reuse the static color definition for white.

ClutterContent's get_preferred_size should return a boolean weather the
preferred size is valid, so in javascript we've to return this state value
before out width and height.
Since this was not happening, clutter was considering the width as the state
(converting the non-zero value to true), the height as the width, while ignoring
the returned height (that was then defaulted to 0)

The default ZoomRegion is created at startup and only updated if it is active
when the monitor setup changes. Thus when reactivating the magnifier after a
display change, the viewport used is still the one that been computed with the
old screen geometry values.
Move screen update code inside a function and call it both when activating
the zoom region and when the monitor changes during a zoom session.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1120
The Magnifier class uses a small subtree of actors to track the
current cursor's position and sprite. Specifically, it uses the
deprecated ClutterTexture to paint the cursor sprites.
Add a new, very simple ClutterContent implementation to track the
cursor sprite, and replace the ClutterTexture by a ClutterActor.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

If there's a caret or focus move we should delay it until the pointer
is stationary for a little while so as to avoid jittery and spurious
viewport movements.

Since the background rework, SystemBackground is no longer a transparent
actor that you have to stack on top of a solid background, it is an
opaque actor. Fix the color of the background actor, and remove places
where we were setting the background color underneath the system background
and expecting blending - in particular, we can always set no_clear_hint
on the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=738652
The design says that the noise texture is the implicit bottom
layer, and so it's appropriate to use it togheter with the default
color to cover the dead area outside the screen which becomes
visibile when scrolling.

In addition to checking the current settings, check also if the
zoom region is active before registering the event listener.
This way, we avoid DBus traffic for events we're not interested in.
Also, make FocusCaretTracker resilient to multiple register/deregister
calls (which can now happen).
https://bugzilla.gnome.org/show_bug.cgi?id=724305
It's possible that the DBus call goes in timeout (which is bad,
but unavoidable, given that atspi is synchronous) or fails
because the component has been removed (race condition). Those
errors are not dependent on gnome-shell, but on faulty applications
(mostly).
If they happen, log a debug message and continue.

The unredirect feature does not apply to the magnifier and it
prevents users from gaming whilst it is on so disable when magnifier
is active and allow magnifier users to game!

Gdk uses Xwayland, so it only sees the events we forward to X11
clients. Instead, we can use the abstraction API provided by
mutter and get the right value automatically.
Also, we need to use MetaCursorTracker to handle the cursor
visibility too.

A11y users who use the magnifier may have trouble
focusing when they're typing or trying to keynav.
Implement a new system so that they can have the
magnifier track the caret and focus instead instead
of just the mouse.

Mutter now includes an object with the same purpose and functionality
as ShellXFixesCursor, so we can replace our XFixes code with it
and work under wayland too.

As description of the setting says, color-saturation ranges from
0.0 (grayscale) to 1.0 (full color), but the real outcome was the
opposite. The reason is that clutter provides a desaturation effect,
and color-saturation was passed directly to that effect. This patch
renames the effect and compute the desaturation value.
This commit adds a grayscale effect to the magnifier, similar to
the lightness, brightness and contrast effects that are already there.
The effect is configured with the
org.gnome.desktop.a11y.magnifier.color-saturation setting, which
can take values from 0.0 (grayscale) to 1.0 (full color).

We seem to have a lot of code that does something along the lines of:
if (condition)
actor.show();
else
actor.hide();
ClutterActor already has such a thing for exactly this purpose: the 'visible'
property. Use it instead of the mess above.

The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().

js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

gsettings-desktop-schemas had two conflicting settings for showing
the magnifier: 'show-magnifier' in org.gnome.desktop.a11y.magnifier
and 'screen-magnifier-enabled' in org.gnome.desktop.a11y.applications.
The former has been removed in favor of the latter, so adjust to this
change.
Since we are keeping a current pointer position anyways, we
don't have to continually call global.get_pointer() which is
a round trip to the magnifier; make ZoomRegion simply fetch
a current position stored in the Magnifier object.

Change the proportional algorithm so stop moving the zoom region
when cursor is in a "padding region" at the edge of the screen.
(The padding region is a 10th of the screen at 2x zoom, and smaller
for higher zooms.)

This basic point of this change is to avoid always creating a
hidden Clutter.Clone actor for the default present-but-not-active
zoom region. The position of the viewport and region of interest
are now stored in member variables, and the actors are only created
and updated when the region is active.
Other significant changes:
* Unused public functions are removed or made private
* The mouse tracking position is immediately updated when options
like the zoom are changed, not just on the next mouse motion.
* ZoomRegion.setROI() now updates the zoom, not just the position;
a FIXME is added to the D-Bus interface for a place where the
D-Bus interface contains duplicate possibly conflicting information
* Lens-mode is now only effectively off when the magnifier is
fullscreen, instead of actually modifying the member variable;
this makes things work properly when changing out of full-screen
mode.
* When the clamping to screen edges is turned on, we now immediately
clamp.
* The handling of setting the position to fullscreen as compared
to just setting the viewport to fullscreen is untangled.

Introduce the Universal Access status indicator as designed, modeled
after the similar UI provided by g-s-d. This indicator allows the user
to change rapidly the keyboard and mouse behaviour (sticky keys, slow
keys, bounce keys, mouse keys), as well as the enabled ATs (magnifier,
screen reader, screen keyboard) and the HighContrast Gtk theme.

The Shell is the only user of the magnifier, so there's no
reason to keep using GConf for its settings. Since it's a
session-wide tool, use a distinct schema,
org.gnome.accessibility.magnifier, stored in
/desktop/gnome/accessibility/magnifier just like before.
Put these settings in a separate schema file for clarity.
Old enums in GConf were stored as integers, we now use the
facilities provided by GSettings to save them as strings,
and convert them to integers automatically thanks to the
mapping stored in the schemas. Remove hard-coded default values,
which we can get from the schemas.
https://bugzilla.gnome.org/show_bug.cgi?id=622414
Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.
A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

This is our convention.
The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
