8d6820c4df magnifier: Do not modify function argument
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.

0d035a4e53 cleanup: Prefer template strings
Template strings are much nicer than string concatenation, so use
them where possible; this excludes translatable strings and any
strings containing '/' (until we can depend on gettext >= 0.20[0]).

1398aa6562 style: Fix indentation errors
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are

f250643385 style: Use space after catch
We are currently inconsistent with whether or not to put a space

that's inconsistent with the style we use for any other statement.

the style gjs/eslint default to.

9158f55360 magnifier: Track cursor sprite changes only when active
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.

7eee0e0ed6 magnifier: Return all parameters on sprite content preferred size
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)

a298943fac magnifier: Update screen position on activation
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.

magnifier: Use a ClutterContent to render mouse sprite
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.

3b1330880f cleanup: Use Function.prototype.bind()
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.

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.
