Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

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.

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.

If the drag actor is destroyed before the animation
callback is called, the callback is never called and
we're sticked with dnd grabing the events after we
dropped the target.
https://bugzilla.gnome.org/show_bug.cgi?id=757676
We need to keep track of the pointer emulating touch sequence. In order
to have events properly redirected on touch devices, the
Clutter.grab_pointer and ungrab_pointer() have been replaced by the grab()
and grab_sequence() ClutterInputDevice methods, one or the other is used
depending on the device triggering DnD.
An extra "sequence" argument has been added to startDrag, passing null here
will resort to pointer grabs.
This is enough to make thumbnails in the WorkspaceBox draggable through
touch.

Removing an existing source before scheduling a new one is not wrong,
but slightly less effective than doing nothing and relying on the
previously created source to do the job.
https://bugzilla.gnome.org/show_bug.cgi?id=711555
As the handler returns false, the corresponding source is removed
automatically and its id invalidated. Reset the id to 0 to reflect
this, otherwise newer versions of GLib will print a warning when
we later try to remove it explicitly.
https://bugzilla.gnome.org/show_bug.cgi?id=711555
I thought that cancelDrag was called for completed drags as well,
but it's not. Move the updateHoverId source removal to dragComplete.
This fixes "this._dragActor is undefined" warnings after completed
drags.

It turns out that picking a 3200x1200 scene on notebook chipsets
every time the mouse is moved isn't exactly the fastest thing. Defer
picking to an idle to ensure that it won't get in the way of keeping
up with mouse events.
https://bugzilla.gnome.org/show_bug.cgi?id=703443
Currently we "only" grab the keyboard when starting a drag operation,
which does not impede keybindings to be processed. This is at best
not harmful (like workspace switching), but may have unintended effects
otherwise - for instance, the hot corner is disabled, so having the
corresponding keyboard shortcut still active is fairly odd (not to
mention that it leaves the system in a confused state).
Fix this by switching to pushModal()/popModal(), which will push a
dedicated keybinding mode for us.
https://bugzilla.gnome.org/show_bug.cgi?id=700877
The actor is the same as the drag actor in this case, but we tend to
set properties on the drag actor and get them from the actor elsewhere
in this codepath. Make this consistent.
https://bugzilla.gnome.org/show_bug.cgi?id=697504
This happens in the case of Workspace/WorkspaceThumbnail: they call
meta_window_change_workspace_by_index(), which fires window-removed
on the old workspace, thus destroying the window clone.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
PopupMenuManager eats the next release event, which would otherwise close
the menu, so we need to tell dnd that we're handling it, and no drag should
be started, so it can ungrab the pointer and restore state.
https://bugzilla.gnome.org/show_bug.cgi?id=694276
To avoid messing up St.Buttons' internal state with a pointer grab,
we wait for the pointer to leave the actor before starting the
drag operation manually. This works generally fine, but makes starting
a drag operation harder than necessary. To fix, enforce a reasonable
button state when starting the drag, rather than special-casing buttons
before the drag.
https://bugzilla.gnome.org/show_bug.cgi?id=637103
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().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
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.
https://bugzilla.gnome.org/show_bug.cgi?id=660358
In the case where the original actor is destroyed, we don't
show a snap back animation, so we need to destroy drag actor
as we would do in _onAnimationComplete.
https://bugzilla.gnome.org/show_bug.cgi?id=640781
During a drag-and-drop, our pointer grab keeps enter/leave events from
being delivered. That means that after the DND ends, whatever actor is
under the pointer won't have received the enter event it should have,
and any state or hover effect dependent on that won't work right.
By paying attention to the actors we leave and enter we can figure out
what widgets we need to call st_widget_sync_hover() on after the drag.
https://bugzilla.gnome.org/show_bug.cgi?id=640974
_ungrabActor disconnects the event signal handler but does not
check whether it is connected before doing so which can result into
an exception like:
JS ERROR: !!! Exception was: Error: disconnect() takes one arg, the signal handler id
JS ERROR: !!! lineNumber = '0'
JS ERROR: !!! fileName = 'gjs_throw'
JS ERROR: !!! stack = 'Error("disconnect() takes one arg, the signal handler id")@:0
We were properly accounting for the fact that an ancestor of the
parent could be scaled rather than the parent itself when computing
the snap-back scale, but directly using parent.scale_x for the
snap-back location.
https://bugzilla.gnome.org/show_bug.cgi?id=642117
For historical reasons, we had both StClickable and StButton, which
were nearly identical. StButton was more widely-used, so keep that and
port all StClickable users to that.
https://bugzilla.gnome.org/show_bug.cgi?id=640583
If the drag actor is destroyed as part of a drag target accepting it,
we were not calling ungrabEvents, meaning the mouse/keyboard remained
grabbed until you clicked somewhere to cancel it.
This fixes that without trying to improve the extremely confusing
control flow...
https://bugzilla.gnome.org/show_bug.cgi?id=635278
Previously, when snapping back a drag actor, we moved it back to its
original stage-relative position and scale. This worked fine if its
parent was still in the same place it was when the drag started, but
failed in cases like the linear workspace layout window drag-and-drop,
where dragging a window would "zoom out" its parent workspace, causing
the snapback to send it to the wrong place.
Fix this by instead snapping the actor back to "where the actor would
have been right now if it were still at its original scale and
position within its original parent actor" rather than "where it was
before the drag started"
https://bugzilla.gnome.org/show_bug.cgi?id=635272
Instead of hiding the drag actor temporarily to determine the actor
beneath it, make it invisible to picks while dragging using the new
shell_util_set_hidden_from_pick().
