GdkWaylandDeviceData conceptually gathers the data that belongs to
a seat, so it's been renamed (although the old typedef stays, plenty
of refactoring is due here...).
The methods in GdkSeatClass have also been implemented, the most
remarkable is ::grab, which ensures the grab is performed on all
the relevant "master" devices.

On some systems, the gtk settings are not used properly for wayland.
Indeed, g_settings_schema_source_get_default is used, and as the docs says it,
"all lookups performed against the default source should probably be done
recursively.".

Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
In Wayland, the hotspot of a DND icon is set using the buffer offset in
wl_buffer.attach. To implement this, add a private API to cause the
next wl_surface.attach to offset the new buffer with a given offset.
Setting a DND icon hotspot sets this offset while also queuing a redraw
of the window to trigger the wl_surface.attach.

gdk-wayland backend would not re-configure a surface when its size and
scale match the known size and scale.
But there might be a pending xdg_surface_configure() that would revert
this change so we should re-configure even if the currently known
size/scale match, otherwise we may end up with a wrong size after the
xdg_surface_configure() is received.

If we "release" the button first, the drag will be eventually cancelled,
we must first signal GDK_DROP_FINISHED, and then release the button so
the success status prevails.
It doesn't make a lot of sense to have this stored as data offer data,
rather together with the source_targets array, which is what we're
poking here in the end.
https://bugzilla.gnome.org/show_bug.cgi?id=758713
Dissociate ownership from our maintenance of wl_data_source objects.
The only place where ownership must be updated together is
data_source.cancelled, for the other places GDK should take care of
setting up the right ownership, even if at a different order than
we'd expect here.
This fixes GTK+ apps on wayland being locally confused about the
current selection ownership. Because gtk_selection_add_targets()
results in a wl_data_source being created, and ownership being
updated right away, early callers of this will change the ownership
even if the widget it's being called on didn't explicitly request
the selection ownership yet.

Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.

After the grab is finished, we would expect an enter event, and
GDK updating internally the cursor for that window and device.
This means there is no need at all to store it separately in the
backend.
As a side effect, animated cursors are now also possible on grab
icons.
https://bugzilla.gnome.org/show_bug.cgi?id=735847
Other backends take care of the cairo surface destruction in
GdkWindow::destroy. We must do the same here, or the cairo_surface
and its corresponding wl_buffer are left dangling.
https://bugzilla.gnome.org/show_bug.cgi?id=747295
If the buffer of a cursor is NULL, for example if its an empty cursor,
just set the cursor surface to NULL as well. Not doing this we'll use
uninitialized hotspot coordinates, dimensions and scales.

This GdkDragContext should be created even if we don't have pointer
capabilities. Make it created on add_seat(), and only set the device
on wl_seat.capabilities, so it can be set to either master pointer.
https://bugzilla.gnome.org/show_bug.cgi?id=741066
We use the high-level gdk_device_get_window_at_position() to figure
out the window, although this one actually tries to find out the
current window under the device coordinates, which might well fall
outside the window, so NULL is returned in those cases.
Fix this by using the lower level _gdk_device_window_at_position()
that will return the toplevel without further lookups, so is more
desirable here.
https://bugzilla.gnome.org/show_bug.cgi?id=758250
Now that we have multiple master pointers, this call may pick the wrong one.
Instead, pick the GdkWaylandDeviceData from the first device, and pick the
master pointer from there.
The common GDK code accounts for "pointer emulating" touch sequences to be
synchronized with the pointer position by the windowing system.
However on Wayland pointer and touch are completely independent, the backend
attempts to implement pointer emulation, but doesn't account for the
possible crossing events happening when the user switches from pointer to
touch or the opposite.
In order to fix this, and to ensure we don't have to interact with the
master pointer (which backs the wl_pointer), separate the touch interface
to have its own master pointer, and ensure crossing events are emitted on
it, so the picture of an "emulated pointer" is complete above the backend.

We were using that range for the extra buttons after left/right/middle,
while this is harmless for clients not handling extra buttons (we
used to translate those button events into scroll events in x11 anyway)
this will be unexpected for clients that do handle additional mouse
buttons themselves (eg. back/forward buttons present in some mice).
In order to remain compatible with X11, those need to be assigned from
button 8 onwards.
Also, include input.h, and stop using magic numbers here.
https://bugzilla.gnome.org/show_bug.cgi?id=758072
Make sure the wayland backend sets a new geometry when the client
resizes itself, otherwise the compositor won't be notified and may
revert to the old size on state changes.
Thanks to Jasper St. Pierre <jstpierre@mecheye.net> who pointed out the
problem in gtk+.

If a GtkMenu (or something else that is mapped as a xdg_popup) tries to
use a subsurface window as a parent, it will be terminated by the
compositor due to protocol violation. So to avoid this, if a parent
window is not a xdg_popup or xdg_surface, i.e. a wl_subsurface, then
traverse up the transient parents until we find the right popup parent.
https://bugzilla.gnome.org/show_bug.cgi?id=756780
Tooltips tend to be placed on top of a parent surface with a given
relative coordinate, and without any input focus. So lets map them as
subsurfaces.
https://bugzilla.gnome.org/show_bug.cgi?id=756496
Restructure the mapping procedure so that its known up front what the
expected way mapping is to be done (subsurface, popup or stand alone),
and warn if it fails to actually map in such a way (for example a popup
without a parent or device grab, a tooltip without a parent).
https://bugzilla.gnome.org/show_bug.cgi?id=756496
GDK_NOTIFY_ANCESTOR would happen when the pointer crosses across a direct
parent/child. However nonlinear events are more likely, specially when
the pointer moves across toplevels (either different apps, or menus being
popped up over the pointer position).
This makes popping up comboboxes and other menus that fall over the pointer
position possible. With the previous detail the GtkMenu code misinterpreted
the crossing event, making it think the button release coming right after
should dismiss the popup, which made menus just flash on the screen unless
you kept the button pressed.
If the shared context is in legacy mode, or if the creation of a core
profile context failed, we fall back to an EGL context in compatibility
mode.
Since we're relying on a fairly new EGL implementation for Wayland, we
don't fall back to the older EGL API, and instead we always require the
EGL_KHR_create_context extension.
https://bugzilla.gnome.org/show_bug.cgi?id=756142
keyboard_handle_leave() might be called with a NULL surface resource
(for example if the surface was destroyed after the event was sent). If
so, we should still deal with the keyboard focus lost event, otherwise
we will both leak (the keyboard_focus GdkWindow reference) and miss
stopping the key repeat timer.
https://bugzilla.gnome.org/show_bug.cgi?id=755927
gdk_wayland_device_update_window_cursor() is inconsistently returning
TRUE/FALSE, despite the timeout being always replaced for new cursor
frames. This could end up in these timeouts being "leaked" and running
as long as the window has an animated cursor.
Fix this by making it really sure we return G_SOURCE_REMOVE, although
now we keep track of animation delays, so the timeout will be reused
for constant time animations.
Initially the subsurface will be in synchronized mode and we will leave
it like this until the first time the parent surface has been committed.
The reason for this is because the subsurface position will be applied
as part of the parent surface state, and we need to synchronize the
initial position with the initial frame, so that we don't accidentally
draw the subsurface at the default position (0, 0) which would happen in
desynchronized mode if the subsurface content is committed before the
next parent surface commit.
https://bugzilla.gnome.org/show_bug.cgi?id=754839
If we are using gl for drawing, we don't have a shm surface,
so don't assert that we do. Instead, only call shm-specific
apis when they make sense.
This fixes a crash when showing popovers over a GtkGLArea,
as seen in gdkgears.

When receiving a selection or when a drag icon enter a window, it was
targeted at a specific window. Lets emit the GDK_OWNER_CHANGE event
only for this window, instead of broadcasting.
Broadcasting has some nasty side effects. For example, if there was n
GdkWindows, and one would for every "owner-change" signal handler
receive n signals about the owner being changed.
An example of where this went a bit out of hand was gnome-terminal,
which added one listener per terminal window. This meant that if
one had m number of terminal windows, each time any one would loose or
gain keyboard focus, O(m^2) owner-change events would be emitted.
