These devices are kind of an strange case. Their "master" device is
the keyboard, because they share toplevel focus with it, regardless
of stylus focus. Nonetheless, they are only expected to send the
GdkEventPad* set of events.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This is a subclass of GdkWaylandDevice that implements GdkDevicePad,
all pad features are looked up from the info obtained through the
tablet v2 interface.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This GdkEventController is a helper object to handle pad events,
it allows setting a mapping to action names, to be triggered in
the given action group.
In order to help on places where advanced mapping/configurability
of pad features is not desirable, this controller also allows
passing a NULL pad device, meaning it will listen on all pads,
and/or passing -1 on mode/index, so an action applies to all
modes/features (eg. strips/rings).
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This is an interface meant to be implemented by the "pad" devices.
This device-specific interface exposes the mapping of all pad features,
it allows retrieving:
- The number of buttons/rings/strips
- The number of groups
- The number of modes a group has
- Whether a given button/ring/strip belongs to a given group
https://bugzilla.gnome.org/show_bug.cgi?id=770026
We want the same treatment for those, the event will be emitted on the
toplevel, which will then decide what to do with the event.
It just doesn't make much sense to propagate those up/down the hierarchy,
when we want specifically one action being triggered from those.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
GDK_PAD_BUTTON*,RING and STRIP will be emitted respectively when
pad buttons, rings or strips are interacted with. Each of those
pad components belong to a group (a pad can contain several of
those), which may be in a given mode. All this information is
contained in the event.
GDK_PAD_GROUP_MODE is emitted when a group in the pad switches
mode, which will generally result in a different set of actions
being triggered from the same buttons/rings/strips in the group.

An xdg-popup requires a serial that the compositor will compare against
its own serial and will dismiss the popup if it doesn't match.
gtk+ uses either a pointer or touch serial for its helper function
_gdk_wayland_seat_get_last_implicit_grab_serial() but if the menu is
triggered before the user has had any pointer or touch interaction with
the client, using a keyboard shortcut, there is neither pointer nor
touch serial available, and gtk+ will use 0 as the default.
As a result, the compositor will instantly dismiss the xdg-popup. In
this case, gtk+ should use the keyboard serial instead.
Track keyboard serial as well and use the keyboard serial as the value
if there is no newer pointer or touch serial available.

At the time of move_to_rect() is called, not all state may have been set
up on the impl gdk window, causing the position to sometimes be
slightly offset due to drap shadow margins. For now, work around this
by postponing the processing of the move_to_rect() parameters until
showing, when its more likely that all state (such as shadow margin)
has been set correctly.

The Wayland backend manages a set of fake root coordinate spaces, where
each non-relative positioned toplevel (i.e. not popups, popovers,
tooltips etc) make up the basis of separate fake root coordinate spaces.
This means that the Wayland backend doesn't have the abilitiy get a
proper root coordinate when querying on a non-toplevel GdkWindow. To
avoid this issue, first find the toplevel, while translating the anchor
rect coordinates so that they are in the toplevel window coordinate
space. Then use this toplevel to translate the coordinates to root
window coordinate space.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
The position of each transient-of will be in fake-root coordinate
space; thus we should not accumulate all the positions making it an
offset; each window is already in fake root coordinate space.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
When using the set transient-for as a popup parent, fetch the effective
toplevel instead, otherwise we will position against the wrong
coordinate.

The effect of transitions-enabled=true can now be
achieved using gtk_popover_popup/popdown and the effect
of transitions-enabled=false can be achieved using
gtk_widget_show/hide.
https://bugzilla.gnome.org/show_bug.cgi?id=769706
Since not chaining up in gtk_widget_show/gtk_widget_hide is not allowed,
we can't just implicitly delay the hiding in GtkPopover's hide
implementation. Fix this by introducing gtk_popover_popup() and
gtk_popover_popdown() to show or hide a popover with transition and
revert GtkPopover's show/hide implementation to apply their effect
without the transition.

The order in which tooltips are created, drawn, shown and then positioned,
always requires repositioning the surface. The tooltip window type only has
limited capability to do so. An alternative could be to use bufferstreams.

When a dialog is created, the mir event source is already executed on the
call stack. So without the recurse flag it will not be run in the main loop
used for the dialog.
