e357559582 cleanup: Mark globals used from other modules as exported
eslint cannot figure out that those symbols are used from other modules
via imports, so they trigger unused-variable errors. To fix, explicitly
mark those symbols as exported.

f6b4b96737 cleanup: Use Array.includes() to check for element existence
We can use that newer method where we don't care about the actual position
of an element inside the array.

(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)

238b87d386 grabHelper: Throw an error if the owner is not an actor
Starting from commit 7bb84dae, GrabHelper requires the owner to be an Actor as
we pass this to pushModal that assumes it to be as well.

So check that GrabHelper owner is an actor and throws an error if it is not the
case. This helps in tracking down issues such as gnome-shell-extensions!68

c59c5eb893 st: Add StDirectionType enum
In order to replace GTK+'s GtkDirectionType. It's bit-compatible with it,
too. All callers have been updated to use it.

This is a purely accessory change in terms of X11 Display usage cleanup,
but helps see better what is left.

bacfdbbb03 cleanup: Port non-GObject classes to JS6 classes
ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

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.

42b54aaa21 grabHelper: handle touch events during grab modality

bbfa616f27 grabHelper: consume the press/motion/release sequence if a press dismisses the grab
The grab would previously just consume the button release, while propagating
motion events, possibly down to clients in wayland. This would produce
inconsistent streams there.

On pointer events, the inconsistency would just be having clients receiving
events with the button 1 set in the mask, with no implicit grab. When touch
events are handled, this would be more hindering as the client would receive
touch_motion events with no prior touch_down nor later touch_up, something
never supposed to happen.

8d9aa6388d grabHelper: Introduce a stack of grab helpers
GrabHelpers use a 'captured-event' to steal events and emulate
modality or grab-like semantics. There can be issues when you try to
use multiple GrabHelpers stacked on each other. As Clutter follows
the DOM-like semantics of "first come, first serve", when a second
GrabHelper connects to 'captured-event', its callback will only be
processed *after* the first GrabHelper's callback is called.

This breaks the expectation of narrowing modality where new modals
take priority over the old ones.

Solving this globally in a cleaner manner would require a rewrite of
pushModal/GrabHelper. As a stopgap fix for now, use one shared
'captured-event' handler between all GrabHelper instances, and
delegate to the individual GrabHelpers.

eef593a34e messageTray: Don't use focus grabs
We can easily implement much of the same behavior ourselves by
keeping track of Clutter's focus events. Reintroduce heavily
modified FocusGrabber to do the work for us.

This will temporarily break when the user selects a window until
we can make gnome-shell automatically set the stage focus.

This also removes our only use of focus grabs, so remove those
as well.

f8ea825577 grabHelper: Consider events that release the grab handled
Currently, if a button-press event results in releasing the last modal
grab (e.g. clicks outside the grabbed actors), we don't consider the
event handled and allow its emission to continue. If we consider
dismissing a grab as an action of its own, any additional action
triggered by the same event becomes an unexpected side effect.
Tweak the capture handler accordingly.

We may release the focus grab at any time, so it's not guaranteed
we'll be in event processing. In particular, hovering over and out

3628c81885 grabHelper: Ignore key focus changes when ungrabbing
Calling onUngrab() may change key focus, either directly or
indirectly (e.g. hiding the actor). Such key focus changes
would cause an extra actor to be ungrabbed, so make sure to
ignore such focus changes while we're ungrabbing.

180000a531 grabHelper: Track the grab before trying to set key focus
If we don't this for a nested grabFocus grab, the notify::key-focus
will be called, not think that the new key focus is part of the
grab, and cancel the full grab. This leaves the grab helper in an
inconsistent and confused state, as the grab is pushed onto the
grab stack after.

60257f422a grabHelper: Restore the actually saved focus on ungrab
GrabHelper saves the actor that had key focus when taking over the grab
(if any). On ungrab, the key focus is either restored or moved to some
child of the saved actor. The latter is unexpected and causes some odd
behavior, so don't be fancy and only restore the actual focus.
