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.
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.
This commit bumps the gtk_shell interface version to 2. By connecting to
a Wayland server with another gtk_shell interface version any features
depending on the gtk_shell protocol will not be available.

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.
When we open the connection, we get the wl_output object,
but we return before all the information such as monitor
geometry has arrived, which causes us to misinform early
users of this information. Do a roundtrip here that causes
us to wait until the information is complete. Do the same
for seats, just in case.

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.

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
write attempt. We already honor the last request properly, so we should just
cancel silently.
The wl_data_source may be the clipboard's. Looking up the drag context in
order to get the display isn't going to fare well there. So, just use the
default display, and only look up the drag context when we know we need it.

Support scaling of cursors created from themes. The default scale is
always 1, but if the pointer cursor surface enters an output with a
higher scale, load the larger version of the cursor theme and use the
image from that theme.
This assumes the theme size is set to one that fits with an output scale
= 1.
https://bugzilla.gnome.org/show_bug.cgi?id=746141
The setting of the the surface scale even when the surface is not
created from a surface was introduced due to a crash when getting the
buffers when dividing by the scale. The only reason I can see this is
that we get the buffer from a non-existing surface when the wl_cursor
has not yet been set.
Instead, use the name field to avoid trying to use the non-existing
surface, effectively avoiding the division-by-zero that way.

When a window is hidden, its surface and all its roles are destroyed,
if this happens when we already issued a wl_surface_commit and are
awaiting for a frame callback, the clock will remain frozen for the
next time the window is shown.
To avoid this, keep track of the wl_surface_frame() calls issued,
and ensure the clock is thawed after hiding. If we happen to receive
the frame callback, it is just ignored.

We were just throwing the request away if the app asks to
fullscreen or maximize a window before it has been mapped.
This is something the GdkWindow API explicitly supports,

This fixes things under weston. There are bugs in mutter
that keep this from working correctly with gnome-shell.

When the Wayland compositor vanishes, all applications connected will
receive a SIGPIPE as soon as they try to use wl_display_dispatch().
Do not use g_error() to terminate the applications when this occurs,
g_error() means an error in the application while here it's not truly
the case.
Use g_warning() and exit() instead.

Before this patch, we'd always allocate a full size SHM buffer via

When the preferred surface scale changes, for example when entering a
wl_output with a higher scale than any previous entered output, recreate
the shm surface and redraw the window content with the new window scale.
Before this patch, the internal scale would be changed, but the shm
surface would not be recreated given the new scale, i.e. we'd attach a
buffer for a different scale than wl_surface.set_scale specified.

It will be useless to check the source window on the destination side,
it's at the moment always NULL. Fetch the display from the device instead,
which will be set for every GdkDragContext.
Some compositors might not offer wl_seat 4 resulting in GTK+ clients not
working on that compositor.
wl_seat 4 introduces keyboard repeat information, but when that information
is missing it is retrieved from settings, hence there's no reason to
require wl_seat 4.

The existence of OpenGL implementations that do not provide the full
core profile compatibility because of reasons beyond the technical, like
llvmpipe not implementing floating point buffers, makes the existence of
GdkGLProfile and documenting the fact that we use core profiles a bit
harder.
Since we do not have any existing profile except the default, we can
remove the GdkGLProfile and its related API from GDK and GTK+, and sweep
the whole thing under the carpet, while we wait for an extension that
lets us ask for the most compatible profile possible.
https://bugzilla.gnome.org/show_bug.cgi?id=744407
Now that we have a two-stages GL context creation sequence, we can move
the profile to a pre-realize option, like the debug and forward
compatibility bits, or the GL version to use.
One of the major requests by OpenGL users has been the ability to
specify settings when creating a GL context, like the version to use
or whether the debug support should be enabled.
We have a couple of requirements in terms of API:
• avoid, if at all possible, the "C arrays of integers with
attribute, value pairs", which are hard to write and hard
to bind in non-C languages.
• allow failing in a recoverable way.
• do not make the GL context creation API a mess of arguments.
Looking at prior art, it seems that a common pattern is to split the
construction phase in two:
• a first phase that creates a GL context wrapper object and
does preliminary checks on the environment.
• a second phase that creates the backend-specific GL object.
We adopted a similar pattern:
• gdk_window_create_gl_context() creates a GdkGLContext
• gdk_gl_context_realize() creates the underlying resources
Calling gdk_gl_context_make_current() also realizes the context, so
simple GL users do not need to care. Advanced users will want to
call gdk_window_create_gl_context(), set up the optional requirements,
and then call gdk_gl_context_realize(). If either of these two steps
fails, it's possible to recover by changing the requirements, or simply
creating a new GdkGLContext instance.

Use xdg_surface_set_window_geometry() to tell the compositor about the
shadow widths, this makes some gnome-shell/mutter features (edge resistance,
frames around windows in the overview, side maximization, ...) work alright
with GTK+.
In order to add this, some other places in gdkwindow-wayland had to gain
some knowledge about margins:
- xdg_surface_configure() now syncs the shadow after applying the state,
and gdk_wayland_window_set_shadow_width() possibly reconfigures the
window in order to preserve window geometry. This is necessary to keep
shadows in sync with state/geometry changes, as this does not happen
all at once.
- xdg_popups relative to an xdg_surface are shown relative to buffer
coordinates, so the left/top margins must be added there.
https://bugzilla.gnome.org/show_bug.cgi?id=736742
It's unused. At the same time, rename "begin_paint_region" to
"begin_paint". This will help us clean up how GDK painting works
in the future to allow more creative use of double-buffering.
Instead of possibly calling wl_surface_commit() out of
GdkFrameClock::after-paint, tick the transient parent clock so ::after-paint
can be eventually run.
This ensures that the subsurface coordinates (considered part of the state
of the parent) aren't committed untimely, and guaranteed to be orderly with
the wl_subsurface-relative state.
This is a gtk-side fix for https://bugzilla.gnome.org/show_bug.cgi?id=738887
cairo_region_copy(NULL) will effectively return an empty region, as this
function is always meant to return valid memory. This however inverts the
meaning of the NULL region and results in entirely non-clickable windows.
We need to use this in the code path where we make the context
non-current during destroy, because at that point the window
could be destroyed and gdk_window_get_display() would return
NULL.
This is not really needed. The gl context is totally tied to the
window it is created from by virtue of sharing the context with the
paint context of that window and that context always has the visual
of the window (which we already can get).
Also, all user visible contexts are essentially offscreen contexts, so
a visual doesn't make sense for them. They only use FBOs which have
whatever format that the users sets up.
To properly support multithreaded use we use a global GPrivate
to track the current context. Since we also don't need to track
the current context on the display we move gdk_display_destroy_gl_context
to GdkGLContext::discard.
wayland doesn't strictly follow the XDG_RUNTIME_DIR spec by falling back
to another directory in case the runtime dir is not properly set.
When this variable is unset, wayland will log an error to us, which we
treat as fatal, aborting the entire program.
Skip ourselves all the trouble and don't try to bring up the wayland
backend when we know it will fail in this way.
https://bugzilla.gnome.org/show_bug.cgi?id=738873
Its not really reasonable to handle failures to make_current, it
basically only happens if you pass invalid arguments to it, and
thats not something we trap on similar things on the X drawing side.
If GL is not supported that should be handled by the context creation
failing, and anything going wrong after that is essentially a critical
(or an async X error).
We make user facing gl contexts not attached to a surface if possible,
or attached to dummy surfaces. This means nothing can accidentally
read/write to the toplevel back buffer.
Currently writing wl_data_offer data into the fd is 1) synchronous, which
is noticeable when transferring large amounts of data, and 2) buggy, write()
error checking is done on the accumulator, breaking both the written data
accounting and error checking itself.
Fix both by making writes asynchonous through GOutputStream, the operation
is spun off and either finished, or cancelled if new data is stored in the
selection while the transfer is active.
The list of devices was being scanned over incorrectly, causing us to
never actually fetch the keymap from the keyboard, as the keyboard was
the second device in the list, not the first.
This causes us to create a new temporary keymap every time, which is
quite expensive, because it involves parsing the entire XKB
file. Scanning the list correctly will cause us to use the XKB rules
file that was passed to us.
A surface may be hidden when a frame is already scheduled, which may cause

Only static cursors are supported in gdk_device_grab() so far. Obey the

On DnD, pointer_handle_leave may be triggered without the pointer actually
leaving the window, and pointer_handle_enter() happening after intra-window

and to the upper layers the cursor is still the same and consistent, so no
attempt will happen).

on enter. The pointer cursor will be updated to any current new one through
the enter/motion events generated if it needs be.

cairo_surface_destroy() is called after the buffer is released, for every
wl_buffer. Windows usually reference their cairo surface before rendering,
so that extra reference is consumed after the buffer is released, so do
the same with cursor surfaces and add an extra reference whenever a cursor
surface change is about to be scheduled.
Otherwise, the GdkWaylandCursor is left with an invalid cairo_surface_t,
which causes crashes the next time it is used.

Delay the keyboard settings creation until we're delivering the key
press. This means we don't have to create the settings for a server that
sends us repeat information.
xdg-shell has moved on and replaced set_margin with set_window_geometry.
To properly support set_window_geometry requires a full rewrite of how
we've been dealing with toplevel windows for now, so just don't set any
margin until we can have a proper toplevel window abstraction in GTK+.
gdk_x11_display_set_window_scale() affects the interpretation of the
Xft/DPI XSETTING - it is substituted inside GDK with the value of
Gdk/UnscaledDPI xsetting. However, this change is not propagated to
GTK+ and from GTK+ back to gdk_screen_set_resolution() until the
main loop is run.
Fix this by handling the screen resolution directly in gdk/x11.
This requires duplication of code between GDK and GTK+ since we still
have to handle DPI in GTK+ in the case that GdkSettings:gtk-xft-dpi
is set by the application.

The way that GtkTextView et al pop up their context menu is to first
query to see if the clipboard has some text, and if so, enable the Paste
menu item. But since the Wayland backend hasn't had the greatest
selection and clipboard code, the callback for the clipboard got dropped
on the floor.
Add some simple code to respond to the TARGETS selection.
This makes right-clicking on a GtkTextView work fine.
Traditionally, the way painting was done in GTK+ was with the
"expose-event" handler, where you'd use GDK methods to do drawing on
your surface. In GTK+ 2.24, we added cairo support with gdk_cairo_create,
so you could paint your graphics with cairo.
Since then, we've added client-side windows, double buffering, the paint
clock, and various other enhancements, and the modern way to do drawing
is to connect to the "draw" signal on GtkWidget, which hands you a
cairo_t. To do double-buffering, the cairo_t we hand you is actually on
a secret surface, not the actual backing store of the window, and when
the draw handler completes we blit it into the main backing store
atomically.
The code to do this is with the APIs gdk_window_begin_paint_region,
which creates the temporary surface, and gdk_window_end_paint which
blits it back into the backing store. GTK+'s implementation of the
"draw" signal uses these APIs.
We've always sort-of supported people calling gdk_cairo_create
"outside" of a begin_paint / end_paint like old times, but then you're
not getting the benefit of double-buffering, and it's harder for GDK to
optimize.
Additionally, newer backends like Mir and Wayland can't actually support
this model, since they're based on double-buffering and swapping buffers
at various points in time. If we hand you a random cairo_t, we have no
idea when is a good time to swap.
Remove support for this.
This is technically a GDK API break: a warning is added in cases where
gdk_cairo_create is called outside of a paint cycle, and the returned
surface is a dummy that won't ever be composited back onto the main
surface. Testing with complex applications like Ardour didn't produce
any warnings.
Weston releases buffers almost immediately after they're done, which
means that GTK+ doesn't use a temporary surface and instead paints
directly onto the SHM backing store that Weston will use.
Normally, after painting to the temporary surface, GTK+ *replaces*
the existing backing surface with CAIRO_OPERATOR_SOURCE. However,
if we immediately paint to the backing surface, it might have junk
from the last paint in it. So clear out the backing surface whenever
somebody calls begin_paint_region().
Maybe we should just always use the temporary surface like the X11
codepath, since that prevents us from having to do weird things like
this, but oh well.
wl_surfaces can't switch roles, so destroying the xdg_surface but not
the wl_surface means that we could get an error when trying to re-map
the surface.
We could fix this by not destroying the xdg resource and only do it at
finalization time, but it's just as easy to just create a new wl_surface.
Since the xdg roles are a special case of the surface, some compositors
like Weston destroy them automatically when the wl_surface is destroyed.
Thus, we need to destroy these first.
The Wayland compositor is completely allowed to send us configure
events for the same size, and this validly happens if we're changing
states. Fizzle these out.
Weston numbers its touch sequences ids starting from 0, thus simply
setting the GtkEvents touch.sequence to the touch id value typically
causes gdk_event_get_event_sequence to return NULL. Unfortunately this
confuses other parts of GDK.
As both weston & mutter keep the sequence id between 0..max_dev_touches
-1 simply use + 1 to keep the id > 0. While this isn't entirely correct
(compositor could send -1 as the touch id), this keeps the touch id in
gtk tied to the touch id from weston which is useful for debugging. A
more thorough solution could be done when it turns out this is an issue
in practise

All the globals we care about should appear before doing anything

Since you can't take grabs on unmapped windows, GtkMenu takes a grab on
the menu in a convoluted way: it first grabs another window, shows the
menu window, and then transfers the grab over to the GtkMenu widget.
For normal menubars, this is perfectly fine, as the first window it grabs
is our toplevel, and that gets picked up in our transient path. For
GtkMenuButton or other spurious uses of gtk_menu_popup, it creates a new
temporary input-only window which it takes the grab on, known as the "grab
transfer window". Since this window isn't a transient-for of our new menu
widget window, the grab isn't noticed when we go to show it, and thus the
menu ends up as a new toplevel.
Add a special hack to GtkMenu and the Wayland backend which lets us notice
this "grab transfer window", and include it in our grab finding path.
It's sort of terrible to have to hack up the widgets instead of just the
backend, but the alternative would be an entirely new window type which is
managed correctly by GDK. I don't want to write that.
The events are routed through a new slave device with type
GDK_SOURCE_TOUCHSCREEN, minimal tracking of touches is done
to keep the state for each of those.

The master pointer/keyboard pair should never disappear or be
inconsistent. The seat capabilities are now reflected through
slave devices, those may come and go freely as the seat

The compositing that is meant here is really specific to the
X11 Composite extension, and does not apply to Wayland.
This is very rarely used functionality anyway, and none of
the other backends support it.
Theoretically, we apply the shape mask client-side ourselves
with an ARGB32 pixmap and intersect it to get a union shape,
but I don't particularly care enough to write that code.
Realistic application code using bounding shapes in 2014 is
quite rare.
It seems that some backends implemented get_root_origin wrong
and returned the client window coordinates, not the frame window
coordinates. Since it's possible to implement generically for all
windows, let's do that instead of having a separate impl vfunc.
Lots of code, including dragging code in GtkWindow, use these
fields. Setting them to 0 causes lots of strange and weird bugs.
Use the same "hack" from query_device_state of just using
win_x / win_y for now. We'll convert this to the proper fake root
coordinate system used by get_root_coords in the next commit.
window->x / window->y are in "root window coordinates", e.g. relative
to the topmost toplevel. However, the coordinates in get_xdg_popup are
relative to the passed-in surface, so we need to do the reverse
translation here.
GtkWindow calls set_shadow_width then maps the window, meaning
that we never set the margin. Save it when we set and then set
it when we create the XDG surface.
Instead of destroying the surface in the backend if this is
unable to resize, let the core code do it, and do it properly.

The code in GDK is incredibly broken and nobody is quite sure what's
right-side-up and what's upside down, but this breaks mutter-wayland
now, so let's remove it. It might leak, but we should probably do a
full restructuring of GDK drawing to fix it.
Like in other backends (except X) we can't resize cairo image surfaces
so let's sync the code here with what the other backends do.
This prevents the painting machinery above us to paint on the wrong
buffer.
https://bugzilla.gnome.org/show_bug.cgi?id=724968
We can't destroy buffers if they're in-use by the compositor. Well,
technically we can, but that is considered undefined by Wayland and
mutter won't cope with it very well -- it simply kills the client.
To solve this, we need to delay the destroy operation until the
compositor tells us that it's released the buffer. To do this, hold
an extra ref on the cairo surface as long as the surface is in-use
by the compositor.
This prevents warnings like
(gtk3-demo:14948): Gdk-CRITICAL **: _gdk_frame_clock_thaw: assertion 'GDK_IS_FRAME_CLOCK (clock)' failed
(gtk3-demo:14948): Gdk-CRITICAL **: gdk_frame_clock_get_timings: assertion 'GDK_IS_FRAME_CLOCK (frame_clock)' failed
We need to do this, as the compositor might have already sent us a frame
event, in-flight, at the same time we destroy our window. In this case, we'll
receive the then-in-flight "done" event, and then warn as we try to look
up the frame clock on a destroyed window.
Add a GtkSetting for whether the desktop shell is showing the desktop

key which is off by default on GNOME.

If a motion event handler (or other handler running from the flush-events

To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.

Some symbols in the generated Wayland code were getting
decorated with WL_EXPORT, causing them to show up in the
libgdk exports. We don't want that.

We may get a NULL region passed to the backend, which means
'nothing is opaque'. In that case, don't crash, but pass
the information on to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=709854
The surface is destroyed when we hide a window, but
gdk_window_set_opaque_region can be called before the window is
shown again, so we need to ensure the surface exits.

In the gnome-ostree model builddir contains all generated files not in
git (unless the build system explicitly overrides that). Here the
wayland-client-protocol.h was in $(builddir)/wayland, so we need to
find it using our already extant -I$(top_builddir)/gdk, rather than
relying on same-directory lookup.
Add the concept of shell capabilities, which allow the compositor
to advertise support for the app menu and the global menubar,
which are then propagated as GdkSettings.

If the compositor supports the gtk-shell interface, use it to

We want a surface so we can properly represent the scale factor for it.
All backends are converted to use surfaces and we reimplement the
backwards compat code in the generic code.
If we don't dispatch the pending events then we can enter poll with events
still requiring to be processed and which can then lead to us deadlocking
there.
Many parts of GTK+ assume that all windows have a cairo surface
assoicated with them. This change provides a logically 1x1 cairo surface
(respecting scale) for the root window.

If we bind to a global with an higher version than implemented, or

With the introduction of the use of buffer scaling in ed4fcee4ct we

Use wl_resource_create() for creating resources
This commit sets the version numbers for all added/created objects. The
wl_compositor.create_surface implementation was altered to create a surface
with the same version as the underlying wl_compositor. Since no other
"child interfaces" have version greater than 1, they were all hard-coded to
version 1.

Ths allows the retrieval of the wl_surface before the window is shown.
The surface is still created in the original places since the surface
and shell surface is destroyed when the surface is programmatically
hidden.
We've long had double precision mouse coordinates on wayland (e.g.
when rotating a window) but with the new scaling we even have it on
X (and, its also in Xinput2), so convert all the internal mouse/device
position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.
We track the list of outputs each window is on, and set the
scale to the largest scale value of the outputs. Any time the scale
changes we also emit a configure event.
We bind to the newer version of the wl_output which supports
the new done and scale events, and if we use this to get the
scale for each monitor (defaulting to 1 if not supported).
If we got the release event for the last buffer then we're
fine with writing directly to the window surface, as wayland
will not be looing at it. This saves us from allocating
and copying more data.
Change the visibility handling to be the same way we do it in
GLib now. We pass -fvisibility=hidden to gcc and decorate public
functions with __attribute__((visibility("default"))).
This commit just does this for GDK, GTK+ will follow later.
When we call _gdk_wayland_display_load_cursor_theme during
the initial opening of the first display, gdk_setting_get does
not work yet, since it relies on the default display/screen
being set, which only happens after open returns.
Instead, just use the screen of this display.
There is currently no Wayland protocol for providing presentation
timestamps or hints about when drawing will be presented onscreen.
However, by assuming the straightforward algorithm used by the
DRM backend to Weston, we can reverse engineer the right values.
https://bugzilla.gnome.org/show_bug.cgi?id=698864
Combine duplicate code for creating and destroying surfaces.
To make the operation of the destroy() operation more obvious, the
destruction of the (fake) root window at display dispose time is
changed to not be a "foreign" destroy.

Use wl_surface_frame() to get notification when the compositor paints
a frame, and use this to throttle drawing to the compositor's refresh

Lazily creating the cairo surface that backs a window when we
first paint to it means that the call to
gdk_wayland_window_attach_image() in
gdk_wayland_window_process_updates_recurse() wasn't working the
first time a window was painted.

When exposing an area, we were individually damaging and committing
each rectangle, *before* drawing. Surprisingly, this almost worked.

This makes Wayland and X11 no longer call into XKB and libX11 for these
functions but use GDK's own copy of these functions, just like the
win32, quartz and broadway backends.
This is another step towards making GdkDisplayManager backend-agnostic.
Most of the backends profit from this as their atom implementations
where generic anyway - x11 needed that to allow multiple X displays and
broadway, quartz and wayland don't have the concept of displays.
The X11 backend still did things, so I only #if 0'd some code but did
not actually update anything.
In the case that the client is started directly by the compositor the
WAYLAND_SOCKET environment variable is set containing the fd to use that was
created by a socketpair.
This environment variable is consumed by a call to wl_display_connect so a
second call will not take advantage of it.
https://bugzilla.gnome.org/show_bug.cgi?id=697673
Under Wayland we don't know the absolute position of the device but there are
some API calls that expect to get an root window position. Previously we were
not assigning any value to these out parameters potentially leaving the values
undefined.
This change returns the current surface relative position of the device.
The is_modifier field is supposed to be set if the key
would act as a modifier, not if any modifiers are currently
active. To fix this, introduce a private
_gdk_wayland_keymap_key_is_modifier function.
At the same time, make the hardware_keycode field in key
events actually contain the hardware keycode, not a copy
of the keyval.
We always emit direction-changed when we get a new keymap, but
for state changes, we compare old and new direction and only
emit the signal when the direction actually changes.
We can get G_IO_HUP and G_IO_IN at the same time, if the compositor writes
data to us and then closes our connection. Make sure that we dispatch events
always if we have G_IO_IN and then error out if we get G_IO_HUP after that.
The cursor buffer is only non-null when a cursor is created from pixbuf,
so it is not necessary to keep track of whether to free this buffer on
finalize.
By keeping a pointer to the wl_cursor struct in GdkWaylandCursor, it is
no longer necessary to duplicate cursor data (width, height, hotspots,
etc.) between wl_cursor and GdkWaylandCursor.
Instead of maintaining the init refcount in regular event handlers that can
fire in case of hotplug or mode changes, use a dedicated sync callback
to wait for roundtrips.
The global_removal argument is the _name_ of the object.
We were comparing it to the _object id_ of the object.
To fix this, store the name at the time the object is bound.
We need to be a bit more careful when updating the screen
size - the code that was there would not do the right thing
if e.g. the width of one monitor was reduced.
We use a ref-count mechanism to track whether parts of the init sequence
still needs round trips to receive remaining initial state. Typically
we need a couple of roundtrips total to get the global list, then the
input and output configurations, but with the ref-count we avoid making
global assumptions like that.

Allow to set a GdkWindow to use a custom surface instead of a
wl_shell_surface. It allows to register the surface as a custom type
with some Wayland interface.

The GDK model for keymaps expects the keymap object to stay
around and emit a ::keys-changed signal. So, do that. This
should make layout changes work, but it remains untested since
weston does not support layout changes at runtime.
At the same time, plug a memory leak where GdkWaylandKeymap
forgot to free its xkb objects in finalize.
https://bugzilla.gnome.org/show_bug.cgi?id=696339
With this commit, we pick up xft settings from GSettings
as well. Among other things, this makes the Large Text
setting work. Still to do: pick up fontconfig changes without
having all clients use up inotify watches for all font
directories.
The check for GDK_CURSOR_IS_PIXMAP was ineffective, since _all_
cursors have this type, from the looks of it. Instead, store
buffer ownership information separately.
These might be candidates for a future settings interface; until
then, we use GSettings directly. Note again that we are careful
to avoid a dependency on GNOME schemas.
Key repeat under X is not affected by modifiers. And on some systems
(e.g my Thinkpad), NumLock is permanently on, rendering key repeat
nonfunctional. This commit changes the Wayland backend to do
key repeat regardless of modifiers.

Commit 0d9d808217 fixed the hotspot issue,
but commit f2cc52fddd then optimized away
cursor changes a little too aggressively. We always need to set the
cursor on enter. Make sure we clear the current cursor on leave so we
don't think it's already set on the next enter.
https://bugzilla.gnome.org/show_bug.cgi?id=695512
Until we figure out where we want to go with settings under
Wayland, this makes GTK+ applications a lot easier to deal
with under Wayland.
Note that we are careful to deal with the absence of schemas,
so this does not introduce a dependency on GNOME settings.
wl_pointer.set_cursor is rejected if the serial number doesn't match
the enter serial number for the wl_pointer. We passed the right serial
number when setting the cursor surface in response to the enter event.
Later set_cursor requests fail, but we can still attach new buffers to
our cursor surface, which is why the cursor changed, but the hotspot
didn't update. Clicking in the decoration results in a leave/enter pair
which triggers wl_pointer.set_cursor with the right serial. That's why
clicking the decoration sets the right cursor.
https://bugzilla.gnome.org/show_bug.cgi?id=695512
We need to pass the delta between the old and new hotspot
when attaching the new cursor surface, to keep the hotspot
at the same position. We can't deal with this in the compositor,
since the set_cursor call already overwrites the old hotspot,
so the information is lost by the time the attach happens.
Unfortunately, we can't query the initial hotspot from
the compositor, so the first cursor change will make the
hotspot jump.
https://bugzilla.gnome.org/show_bug.cgi?id=695512
Use separate fields for saving the window dimensions prior to fullscreening
and maximisation. Then use those fields to restore the window dimensions from.
With recent changes in attach semantics, we always need to attach before
committing. Without this changes to the window contents to not get reflected
in the content of the surface.

When events are paused, we should not return TRUE from prepare() or check().
GTK+ handles this for events that are already in the GTK+ queue, but
we also need suppress checks for events that are in the system queue - if we
return TRUE indicating that there are events in the system queue, then we'll
call dispatch(), and do nothing. The event source will spin, and will never
run the other phases of the paint clock.

Deprecate gdk_window_enable_synchronized_configure() and
gdk_window_configure_done() and make them no-ops. Implement the
handling of _NET_WM_SYNC_REQUEST in terms of the frame cycle -
we know that all processing will be finished in the next frame
cycle after the ConfigureNotify is received.
Allows to access Wayland specific window information like wl_surface and
wl_shell_surface.
Add gdk_wayland_window_get_wl_surface for getting the Wayland wl_surface
and gdk_wayland_window_get_wl_shell_surface for getting the Wayland
wl_shell_surface.
In the Wayland backend implementation for gdk_display_get_keymap we enumerate
the known devices and look for an core keyboard device. These device objects
are created when we receive the capabilities for the seat. The seat
capabilities may be received after a request for the keymap so we handle this
by creating a temporary keymap which we then free later when we have the real
one.
libxkbcommon has had some changes to its API. However, it now has a
stable release (0.2.0), so this makes the necessary changes, and
replaces all uses of the deprecated API.
