-1 means that we have no specific preference for an initial
fullscreen monitor, and -1 is less than the number of monitors,
so we would end up accessing invalid memory. Prevent that.

Make broadway_server_read_all_input_nonblocking return a boolean, TRUE

Windows does not send any release key event for one of the shift keys
when both shift keys were pressed together. This commit solves
the problem by sending the extra release key event for the shift key
which was released as first, when the other shift key is released.
Other modifiers (e.g. Ctrl, Alt) do not have this problem.

So a window can be maximized/zoomed again after being moved away from
its maximized position. This makes the zoom button on non-CSD windows
work as before.
Instead of using the default zoom behaviour use the internal
maximized state for selecting our own zoom target. This makes
zooming work for CSD windows where for some reason the
given default zoom target is the current window frame itself
resulting in a shadowless window of the same size.
While this makes the zoom button behave a bit different as expected
it makes things more consistent with other platforms and fixes CSD
zooming.
Prior to this patch, the hotspot would be passed in buffer coordinate
space. Where this were ever tested, i.e. in a patched mutter, the
server interpreted them incorrectly, which meant it went undiscovered.
In the updated mutter patches the incorrect behavior in GTK+ was
discovered due to the behavior in mutter was corrected.
In the themed cursor case, the dimensions were not correctly scaled
either, but this had no negative visible effect because the dimension is
only used for reporting damage tracking, and passing a bigger damage
region than surface has no negative visible effects.

When using frame times from _NET_WM_FRAME_DRAWN and _NET_WM_FRAME_TIMINGS, we
were treating them as local monotonic times, but they are actually extended-precision
versions of the server time, and need to be translated to monotonic times in the
case where the X server and client aren't running on the same system.
This fixes rendering stalls when using X over a remote ssh connection.

Avoid using a stale timestamp (from the last user interaction with the
application) when a message arrives from D-Bus requesting that a new
window be created.
In this case the most-correct thing that we can do is to use no
timestamp at all.
We modify gdk_x11_display_set_startup_notification_id() to allow a NULL
value to mean "reset everything" and then call this function
unconditionally on receipt of D-Bus activation requests. The result
will be that a missing desktop-startup-id in the platform-data struct
will reset the timestamp.
Under their default configuration metacity and mutter will both map
windows presented with no timestamp in the foreground. This could
result in false-positive, but there is very little we can do about that
without the original timestamp from the user event.
https://bugzilla.gnome.org/show_bug.cgi?id=752000
If we don't find Xft values in the X resource db, simply fall
back to the values that are hardcoded in /etc/X11/Xresources
anyway. Extra trickery with likely-made-up screen dimensions
is not going to yield better results, and only makes for a
deeper rabbit hole when debugging.
Support was added for GDK_HINT_ASPECT in
gdk_quartz_window_set_geometry_hints though with one restriction:
min_aspect and max_aspect have to be equal, which I believe corresponds
to the most common usage. A warning will be printed if this condition is
not met but min_aspect will be used anyway.
Under Wayland, fullscreen/maximized windows may not cover the entire
area when a size increment is specified.
Ignore size increments for fullscreen/maximized windows just like most
window managers do under X11 so that windows with size increments can
still be fullscreen or fully maximized under Wayland as well.

We used to "invalidate" scroll valuators, so the next scroll event could
be used as the base for the next scroll deltas. This has the inconvenience
that it invariably consumes the first event received after enter and,
due to interactions with WM overeager passive button grabs, there's a
possibility we don't scroll at all if we receive interleaved "smooth
scroll" XI_Motion events and XI_Enter events (Normally triggered by regular
scroll wheels in mice).
In order to fix this, and at the expense of some sync-call overhead on
XI_Enter events (one XIQueryDevice call per slave device), query the
current scroll valuator state for all the slaves of the entered pointer,
so we do know beforehand the right base values. If new devices are plugged
while the pointer is on top of the client, the initialized scroll values
will match the valuators'.

gdk_x11_device_xi2_window_at_position() may attempt to push/pop

We mistakenly forced the "STRING" type, which was able to confuse higher
layer helpers like gtk_selection_data_get_uris(). This fixes a crash
happening anytime a drop is attempted on a GtkPlacesSidebar.
Currently, due to the lack of progress information in the Wayland DnD
protocol, we assume a DnD operation is finished after the first
data_source.send is finished (It's either that or leaving stuck grabs).
This however breaks previous assumptions that dest widgets can request
the data multiple times, even in response to GtkWidget::drag-motion.
This leaves us with a NULL owner for the DnD atom when we aren't
finished receiving wl_data_source events yet, causing a crash.
This commit fixes the crash, the behavior left is still far from
desirable though...
And force the ungrab on it, instead of the slave, in the case of
local DnD drop. This avoids confusions on the pointer events spawn
from DnD, as GDK doesn't think anymore those are from a slave device.
Most namely, it fixes the stuck grab when finishing DnD on the
same app it was started from.
We currently only hold the last offer received, which is wrong, as both
are independent and have different life cycles.
This means we have to store per-selection wl_data_offer and targets, and
maintain these as appropriate from the clipboard/DnD specific entry points.
This oddly can be reproduced with weston+weston-dnd, when dragging
anything from GTK+ into weston-dnd, it will insist on picking its
custom application/x-wayland-dnd-flower mimetype, and this request
forwarded by the compositor, even if GTK+ didn't announce it on
its wl_data_source mimetype list. (What should probably happen here
is that the request is silenced, and/or weston-dnd picks (null))
This should be harmless, we are leaking though the fd in that case,
because the emission of GdkEventSelection on an unhandled mimetype
results in NOP. In order to avoid this, we should check whether the
mimetype is supported at all on the backend code and possibly close
the fd, this involves storing these in the first place.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
If the other peer requests data too fast (too rare/unlikely though),
we might receive multiple gdk_wayland_selection_request_target() calls
with no ending gdk_wayland_selection_check_write(), in which case the
fd is leaked as no GOutputStream was created to take over it.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
We weren't catching all the places where the AsyncWriteData operation
should be cancelled, which could happen if we repeatedly request the
same target on different fds.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
At the moment we create the AsyncWriteData, the ownership of the
fd is granted to the GOutputStream, and the fd set to -1, so at
this moment we're just silently getting EBADFD.
This partially reverts 25885ca600, the initialization of .fd
to -1 is valid and stays though.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
On X11 this is something the windowing system does for us, which the
wayland backend should emulate, being grabs completely client-side.
So, if the grab and current focus windows differ, make sure we emit
focus/crossing events as it corresponds to the grab device.
This was being done so only on pointers. Internally, a GdkDeviceGrabInfo
is kept for each of the master pointer/keyboard, failing to do this for
keyboards results in a stuck keyboard grab.
https://bugzilla.gnome.org/show_bug.cgi?id=748892
The fd must be closed on async_write_data_free(), but we should also
initialize it to -1 so gdk_wayland_selection_check_write() doesn't wrongly
pick the stdin fd.

A subsurface positioning operation only takes effect when the parent
surfaces state is applied. If a subsurface is mapped and positioned, but
the parent surface state is not immediately committed, the relative
position of the subsurface is undefined and may be placed incorrectly.
To avoid this undefined state, always request that the parent surface
should be committed after mapping a subsurface so that the position
operation will take effect.

Background patterns are often updated when style changes. In many cases,
the new pattern will match the previous. We can optimize out the
invalidation that will occur upon resetting the same pattern.
An pass_through window is something you can draw in but does not
affect event handling. Normally if a window has with no event mask set
for a particular event then input events in it go to its parent window
(X11 semantics), whereas if pass_through is enabled the window below
the window will get the event. The later mode is useful when the
window is partially transparent. Note that an pass-through windows can
have child windows that are not pass-through so they can still get events
on some parts.
Semantically, this behaves the same as an regular window with
gdk_window_set_child_input_shapes() called on it (and re-called any
time a child is changed), but its far more efficient and easy to use.
This allows us to fix the testoverlay input stacking test.

If a menu was not attached to any widget, we try to calculate its
position given where the grabbed pointer is and what window has its
focus. Previously we failed to do so if a "transfer window" was used
for the grab, and this patch adds a code path that, if the menu window
itself didn't have the grab, look for the transfer window and get the
grab device from there.

If a position was already explicitly set, don't try to guess the
position of popup menus by looking at the pointer position, just use
the set coordinates.
https://bugzilla.gnome.org/show_bug.cgi?id=748951
According to the xdg-shell protocol specification the (x, y) coordinates
passed when creating a popup surface is relative to top left corner of
the parent surface, but prior to this patch, if the parent surface
was an xdg_surface, we'd position it relative to top left corner of the
window geometry of that xdg_surface.

On wl_keyboard.key/modifiers, we're just forgetting about currently
pressed mouse buttons. Fix this by storing button and key modifiers
separately, and put these together when creating the GdkEvents.
This patch introduces support for using the newly introduced
monitor objects in the XRandR protocol. These objects are meant
to be used to denote a set of rectangles representing a logical
monitor, and are used to hide details like monitor tiling and
virtual gpu outputs.
This uses the new objects instead of crtc/outputs objects when
they are available to create the monitor lists. X server 1.18
is required on the server side for randr 1.5.

Load themed cursors from the same places they are loaded on freedesktop systems,
but use W32 API functions to do so (works for .cur/.ani cursors instead of X
cursors).
Refactor the code for cursor handling. Prefer loading cursors by name.
Do not load actual cursors when loading the theme. Find the files and remember
the arguments/calls for loading them instead. Keeping HCURSOR instance in the
hashmap would result in multiple GdkCursors using the same HCURSOR. Given that
we use DestroyCursor() to off them, this would cause problems (at the very
least - DestroyCursor() would fail).
Store GdkCursor instances in a cache. Update cached cursors when theme changes.
Recognize "system" theme as a special (and default) case. When it is set,
prefer system cursors and fall back to Adwaita cursors and (as a last resort)
built-in X cursors. Otherwise prefer theme cursors and fall back to system and
X cursors.
Force GTK to use "left_ptr" cursor when no cursor is set. Using NULL makes
it use the system default "arrow", which is not the intended behaviour when
a non-system theme is selected.
Ignore cursor size setting and query the OS for the required cursor size, as
Windows (almost) does not allow setting cursors of arbitrary size.
https://bugzilla.gnome.org/show_bug.cgi?id=749287
In particular this means that cursors are disposed of by the way of
g_object_unref(), not DestroyCursor (which is documented to not to be
used on certain kinds of cursors, and we can't tell which is which).
It should also alleviate any concerns about destroying cursors that
are still in use by other windows, except for cases where we would
somehow get our hands on a HCURSOR that someone else is using and we
make a GdkCursor out of it and later unref and finalize it while it
is still in use.
It also removes the need to call CopyCursor(), which makes animated
cursors into non-animated ones as a side-effect (supposed to be a bug,
but try explaining that to MS). Now cursors should be animated (if
the are set up as such in the OS).

Some features need certain globals to initialize. In order to deal with
these dependencies, add a way to postpone closures that depend on a
certain set of globals, that later will be invoked when required
globals are all received.
https://bugzilla.gnome.org/show_bug.cgi?id=719819
Instead use asynchronous round trips that is synchronized in the end of
the initialization. This makes it easier to track state, as we won't
dispatch arbitrary Wayland messages while processing globals.

Only "wait" and "all-scroll" are not implemented properly. OS X does not
seem to have a proper interface to either cursor. Approximations are used
instead; see the code.
See bug 749178.
The ordering of globals in connection setup under weston
is different from mutter, and we end up creating a the
dnd window before any outputs are present. Don't cause
a critical warning in that case.
Even when the program itself calls gdk_set_program_class(). There's
currently no way for this function to be called without breaking gdk's
--class command line option, because you cannot call it before
gtk_init().

This is purely to support gdk_cursor_new_from_name().
In particular, its counterpart, gdk_cursor_new_for_display(), will not
be affected, because there's no GDK_LEFT_PTR_WATCH cursor type,
and because i don't have a fallback cursor bitmask for gdk/win32/xcursors.h
We interpret buttons 4-7 as old-school scroll events, so it does
not make sense to add these to the mask. Also fix an off-by-one
in the loop here, buttons_mask is 1-based.
We now have proper checks for gdk_screen_is_composited() and a proper
implementation for gdk_screen_get_rgba_visual() for Windows, so we
can remove the comments in this file stating that they aren't
available for Windows.
I was getting really weird values for scale for the blank cursor used
when hiding the cursor in a GtkEntry when typing, this was caused
by gdk_wayland_device_update_window_cursor sending random values
when the returned buffer was NULL.
We fix this by just not sending any buffer or scale updates in this
case.
Requires Vista and newer.
* Create surfaces with cairo_win32_surface_create_with_format
* Provide an rgba visual that can be distinguished from the system visual
* Make rgba visual the best available visual
* Enable alpha-transparency for all windows that we control
* Check for appropriate cairo capabilities at configure time
(W32 - 1.14.3 newer than 2015-04-14; others - 1.14.0)
* Check for composition support before enabling CSDs
* Re-enable transparency on WM_DWMCOMPOSITIONCHANGED
Windows that were created while composition was enabled and that were CSDed
as a result and will look ugly (thick black borders or no borders at all) once
composition is disabled.
If composition is enabled afterwards, they will return back to normal.
This happens, for example, when RDP session is opened to a desktop where a GTK
application is running. For W7/Vista windows will only re-gain transparency after
the RDP session is closed. For W8 transparency will only be gone momentarily.
Windows that were created while composition was disabled will not be CSDed
automatically and will use SSD (WM decorations), while windows that are CSDed
manually will get a thin square border.
If composition is enabled afterwards, these windows will not change.
This is most noticeable for system menus (popup menus are often generated
on the fly, system menus are created once) and some dialogues (About dialogue,
for example).

GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
Add two new requests to the gtk_surface interface: set_modal and
unset_modal. The server will currently not do anything special with
input focus, and its up to the client to ignore events on the parent
surface.

a Wayland server with another gtk_shell interface version any features
depending on the gtk_shell protocol will not be available.

cairo_rectangle_int_t was replaced by GdkRectangle in commit
552c29b488, but the type of the pointing-to
property was not changed.
To avoid breaking old code that sets or gets the property with a GValue
of type CAIRO_GOBJECT_TYPE_RECTANGLE_INT, transformation functions between
CAIRO_GOBJECT_TYPE_RECTANGLE_INT and GDK_TYPE_RECTANGLE are registered on
the first call to gdk_rectangle_get_type().

gdk_wayland_drop_context_set_status() can't do much else currently besides
picking a mimetype (the first one is currently chosen). This may incorrectly
unset the mimetype chosen on .receive(), so the transfer is cancelled before
it even starts.
At the time drop_reply happens, we should have already picked a mimetype
along the way, so only cover for accepted=FALSE in order to unset it.
During drag operations from another client, we currently set no window as
the DnD source. There's paths in upper layers though that rely on it being
set, just that we don't trigger these yet.
This reverts commit 24d3f3fcb2.
Sorry, I am going to re-commit this very shortly with a new
commit message, as I found the commit message to be quite
wrong and misleading.
The current GdkScreen->is_composited() is a stub as we were having Windows
XP being supported, which does not support Desktop Window Manager (DWM),
which is used by Windows for composition.
Windows Vista and later support DWM, and it is always enabled on Windows 8/
Server 2012 and later.
Please note that as we are dropping XP support in this cycle, this is the
commit that would say goodbye to Windows XP support for GTK+-3.x, by
linking directly to dwmapi.dll. This means, we only check whether we are
on Windows 8 or Server 2012 (or later) to see whether we unconditionally
have composition enabled.

When we open the connection, we get the wl_output object,

The "app_id" of a xdg_surface should be the ID that can potentially be
used to get the DBUS name or the .desktop file.
For GtkApplication programs this is often the ID passed when creating the
GtkApplication object, so when available lets use that.
As fallbacks, first try g_get_prgname as it often corresponds to the
basename part of the .dektop file for non-GtkApplication programs.
Otherwise use gdk_get_program_class, even though that string usually
doesn't conform to the expectations of xdg_surface.set_application_id.

If the GLX_EXT_texture_from_pixmap extension is not available when we

Use screen workarea to *also* set the position of a maximized window,

During copy/paste, it may be common that we receive several property changes
around the selection atom, this results in warnings when cancelling the previous
