a32c4f30d1 style: Allow lonely ifs where appropriate
We now have a lint rule to disallow lonely ifs, however there are
cases where the "lonely" part mirrors code from the preceding if
clause. Opt out of the lint rule in those cases.

ebf77748a8 cleanup: Require "dangling" commas
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.

c860409da5 cleanup: Use object shorthand where possible
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.

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

We are currently inconsistent with whether or not to put a space

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.
