5bc8a0860a tweener: Remove the onAnimationStart/onAnimationComplete callbacks
Our gnome-shell tweener integration has had hooks to determine when
the tweens have started and completed... except that they had a bug
in them. When a tween completed, it queued an idle handler to run
the callback in. If no tweens were running when the idle was removing,
it reset the tween state that contained the idle handler ID. It also
returned false, meaning that the source would always get removed.

If the actor had a tween in-flight when the idle was fired, it wouldn't
clean up after itself. While this is also a simple bug fix, remove the
callback so we don't queue unnecessary, unused idles.

96e02c4c2e tweener: Look at the XSetting for disabling animations
gnome-settings-daemon will be changed to override the XSetting in
the case where we're on a remote display rather than overwriting a
user setting, so we need to look at the XSetting here.

207abe9a2c tweener: make timeline loop indefinitely
Tweener uses a clutter timeline to manage all active animations
running at a given moment.  The timeline is mopped up when no
animations are going any more.

Clutter requires timelines to have a finite duration, but since
animations can happen at any moment, no fixed duration can
accomodate the shell's needs.

To combat this problem, the tweener code picks a relatively
long duration: 1000 seconds. No string of animations should take
that long, so, in theory, that should be good enough.

Unfortunately, this tactic fails, in practice, when the user
suspends their machine, or VT switches.  An animation can take
much longer than 1000 seconds (~16 minutes) to complete in those
cases.  When the user resumes, or VT switches back the timeline
completes immediately (since it's already late) and tweener
never notices that the timeline stops ticking.

This commit changes the tweener timeline to automatically loop
back to 0 after completing, so that despite its fixed duration
property, it effectively never stops. Since the timeline loops,
its concept of elapsed time no longer increases monotonically,
so we now ignore it and track time ourselves with
GLib.get_monotonic_time().

This partially reverts commit

17c46c2452 Port everything to class framework
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().

75b824d032 *.js: Make emacs modelines consistent
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.

192d3a94ed tweener: remove tweens when target.actor is destroyed
We already remove tweens automatically when a Clutter actor is destroyed;
do the same when the target is a JS delegate with an actor property.

35764fa09e Move Tweener.slowDownFactor into St
It has probably crossed the line to evil by a mile or so, but here
it is: a Tweener.slowDownFactor replacement used by all animations
without exception.
While at it, update Tweener to use the new setTimeScale() upstream
function instead of adjusting the timeline directly.

07cfb8d524 [perf] add tweener.framePrepareStart/Done events
Add events when we start preparing a frame and finish preparing
a frame. (In addition to measuring property-updating overhead, this allows
us to see the interval between finishing preparing a frame and starting
painting the frame, which is the relayout time.)

a9a513c621 Add "leisure function" capability
To support scheduling performance-measurement scripts that want to run
a number of actions in series, add shell_global_run_at_leisure() to run
a callback when all work is finished.

The initial implementation of this is not that accurate: we track
business in Tweener.js via new shell_global_begin_work(),
shell_global_end_work() functions, and we also handle the case
where the main loop is continually busy.

703b21cef0 Don't use double quotes for things that don't need to be translated
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
of the output string.

e79c776c2e Add a wrapper around tweener to do some extra integration
Automatically removes tweens on destroyed actors, and provides
additional "animation started/stopped" callbacks (eg, for tracking
whether or not to show window clone titles)
