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)

3e0915521a magnifier: Only connect to signals when ZoomRegion is active
There's no need to listen signals when the zoom region is inactive, so let's
just connect/disconnect them.

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.

a7bb8ee639 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.

bacfdbbb03 cleanup: Port non-GObject classes to JS6 classes
ES6 finally adds standard class syntax to the language, so we can

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.

zoom region is active before registering the event listener.

errors are not dependent on gnome-shell, but on faulty applications
(mostly).
If they happen, log a debug message and continue.

7431c4d611 magnifier: Using properly 'color-saturation'
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.

8754b2767c Add a grayscale effect
This commit adds a grayscale effect to the magnifier, similar to

The effect is configured with the

can take values from 0.0 (grayscale) to 1.0 (full color).
