68e580e394 dialog: Use GObject.set() over Object.assign()
gjs has provided that as a more idiomatic replacement for a while.

2e5295b3a9 dialog: Use object's set to assign properties
We can just assign a properties object to a GObject using the set() method
instead of using Object.assign.

3121c9aa29 dialog: Really set ellipsize mode in subtitle and body
Dialog's subtitle or body could not be properly wrapped, while it's ellipsized
when the text's width doesn't exceed the container size.

Clutter text has an `ellipsize` property, however in dialog's subtitle and body
we have been setting the `ellipsize-mode` property to Pango.EllipsizeMode.NONE
that is not present in the underlying GObject.

Not being an error in javascript, gjs didn't warn us about this, while at the
same time the St.Label's default Pango.EllipsizeMode.END was used.

fd50b9a45e cleanup: Use destructuring for imports from GI
This is *much* nicer than repetitive "imports.gi" lines ...

e68dfed1f7 cleanup: Port GObject classes to JS6 classes
GJS added API for defining GObject classes with ES6 class syntax
last cycle, use it to port the remaining Lang.Class classes to
the new syntax.

f77b3da74f js/ui: Choose some actors to cache on the GPU
Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.

This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:

 * Repainting an offscreen actor is measurably slower than repainting
   the same actor if it was uncached. But only by less than 100%,
   so if an actor can avoid changing every frame then caching is usually
   more efficient over that timeframe.

 * The cached painting from a container typically includes its children,
   so you can't cache containers whose children are usually animating at
   full frame rate. That results in a performance loss.
     This could be remedied in future by Clutter explicitly separating a
   container's background painting from its child painting and always
   caching the background (as StWidget tries to in some cases already).

So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:

One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)

Also a couple of bugs are fixed by this:

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.

76f09b1e49 cleanup: Use method syntax
Modern javascript has a short-hand for function properties, embrace
it for better readability and to prepare for an eventual port to
ES6 classes.

100d6a7fa7 dialog: Reset initial focus on destroy
Since 0b02f757f8 we track the button that should have key focus
when the dialog is opened. However when the dialog is reused, the
button may get destroyed - clear the initial focus in that case to
allow setButton() to set a new one.

0b02f757f8 dialog: Fix setting buttons as initial key focus
Commit 1c7a3ee61b broke setting the initial key focus for default
buttons added via addButton(). Fix this by allowing the dialog class
to provide a different default widget to ModalDialog than the entire
dialog itself.

2582d16ca7 Define classes with 'var' instead of 'const'
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.

b5860d687d dialog: Add MessageDialogContent
A lot of our modal dialogs share a similar structure:

 [Icon]   Some title
          Maybe a subtitle

          And sometimes even a body for stuff like
          longer descriptions.

A dedicated widget with a common style will allow us to significantly
reduce duplication of both code and CSS.

1c7a3ee61b ui: Refactor modal dialog into separate Dialog class
This is the basic dialog actor implementation, which will allow us to
use the same implementation on the session-global modal dialogs. The
ModalDialog class now uses it underneath, and so do all users of it.
