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.

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.

When using the set transient-for as a popup parent, fetch the effective
toplevel instead, otherwise we will position against the wrong
coordinate.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=768138
The event will be sent when the surface becomes visible on an output. With this change the GdkMirWindowImpl keeps track of the scale value and sends a configure event on change.

The event code could potentially dereference pointer_info if the
invariant that ENTER_NOTIFY and LEAVE_NOTIFY events are only emitted on
devices which have pointers is violated elsewhere.

Pick the W32 API for possible deadkey+<something> combinations
and prefer these to other sources of deadkey combos.
Specifically, if W32 API supports at least one combo for a particular
deadkey, only use that data and do not attempt to do other, unsupported
combinations, even if they make sense otherwise.
This is needed to, for example, correctly support US-International
keyboard layout, which produces a combined character for <' + a>
combo, but not for <' + s>, for example.
This is achieved by stashing all the deadkeys that we find in
an array, then doing extra loop through all virtual key codes and
trying to combine them with each of these deadkeys. Any combinations
that produce a single character are cached for later use.
In GTK Simple IM context, call a new GDK W32 function to do a lookup
on that cached combination table early on, among the "special cases"
(which are now partially obsolete).
A limitation of this code is that combinations with more than
one deadkey are not supported, except for combinations that consist
entirely of 2 known deadkeys. The upshot is that lookups should
be relatively fast, as deadkey array stays small and the combination
tree stays shallow.
Note that the use of ToUnicodeEx() seems suboptimal, as it should
be possible to just load a keyboard library (KBD*.DLL) manually
and obtain and use its key table directly. However, that is much more
complicated and would result in a significant rewrite of gdkkeys-win32.
The code from this commit, though hacky, is a direct addition to
existing code and should cover vast majority of the use-cases.

This changes the group/level semantic.
Previously W32 backend used "group 0/1" to denote "AltGr OFF/ON"
and "level 0/1" to denote "Shift is OFF/ON".
Now "group" means "keyboard layout" and there can be up to 255 groups,
while AltGr and Shift are combined into a single level enum that
takes values between 0 and 4.
Unlike X, W32 doesn't do effective group overriding, meaning that
it will never tell the caller that a different group was actually
used (even for universal keys, such as Enter), because key symbol
table is completely fabricated and there's no point in trying to
save a few of kilobytes of RAM by not duplicating universal key
records for all groups.
Also contains many whitespace changes (tab elimination, fixed
indentation) and cleanup (axed a few global variables, these are
now accessed via the default keymap).

This matches the behaviour of Mutter, Metacity and traditional X11
window managers on the window manager side, and is what we want
for at least gnome-terminal. I can't think of any reason why we'd
want incremental resize in any other tiled window.

Bug: https://bugzilla.gnome.org/show_bug.cgi?id=760944https://bugzilla.gnome.org/show_bug.cgi?id=755947
Only update to using v2 headers/structs. The incompatible changes
to tool events are dealt with in the next commit. Pads aren't handled
in this commit either.
The sizes passed are in device pixels and do not take into account the
scaling factor of the window itself. We cannot change the semantics of
the function, so let's at least add a warning for this trap door.
On X11, device_query_state() uses XIQueryPointer() which will return a
child window only if the pointer is within an actual child of the given
window.
Wayland backend would return the pointer->focus window independently of
the given window, but that breaks the logic in get_device_state() and
later in gdk_window_get_device_position_double() because the window is
searched based on coordinates from another window without sibling
relationship, breaking gtkmenu sub-menus further down the line.
Fix the Wayland backend to mimic X11's XIQueryPointer() to return a
child only if really a child of the given window.
That's the most sensible thing to do to fix the issue, but the API here
seems to be modeled after the X11 implementation and the description of
gdk_window_get_device_position_double() is not entirely accurate.

This has most notably impact in selection buffers, because those were
shared across all selection atoms. This turned out wrong on 2 situations:
- Because the selection atom was set at SelectionBuffer creation time, the
GDK_SELECTION_NOTIFY events generated will have unexpected info if the
buffer is attempted to be reused for another selection.
- Anytime different selections imply different stored content for the same
target.
This is better separated into per-selection buffers, so it's not possible
to get collisions if a same target is used across different selections.

The sanitize_utf8() function has been copied from X11 so both
backends behave the same. This allows interaction with older clients
(mainly through Xwayland, and the STRING selection target) that
request non-utf8 text.

Debian stable currently ships with a 3.16 kernel, so
it doesn't have memfd available.
This commit adds shm_open fall back code for that case
(for now).

We currently use syscall() directly to invoke memfd_create,
since the function isn't available in libc headers yet.
The code, though, mishandles how errors are passed from syscall().
It assumes syscall returns the error code directly (but negative),
when in fact, syscall() uses errno.
Also, the code fails to retry on EINTR.
This commit moves the handling of memfd create to a helper function,
and changes the code to use errno and handle EINTR.

When disposing a GdkDrawingContext we should unset the association
between the instance and the Cairo context; this avoids stale pointers
in case a reference that has acquired on the Cairo context survives the
lifetime of the GdkDrawingContext.
