Having the same, usable, default appearance acroll platforms
trumps having a more-or-less working native theme. The default
will be Adwaita on all platforms. The native ms-windows theme
is of course still available.
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

There are plans to add session-dependent defaults to GSettings
(based on the newly standardized XDG_CURRENT_DESKTOP); until
then, the WM uses a different schema for its button-layout
setting in classic mode. So for the time being, do the same
and pick the alternative schema when XDG_CURRENT_DESKTOP
indicates that we are in a classic session.
(It's not pretty, but hopefully won't be with us for too long ...)
https://bugzilla.gnome.org/show_bug.cgi?id=731273
Pick up the setting from the org.gnome.desktop.wm.preferences schema
if available. It is slightly more involved than other settings, as
the actual button names used in the schema differ from the ones we
use, so we need an additional translation step.

When the pointer cursor is updated on CSW, lookup for either a device
cursor, or a global one. It would previously lookup for windows with
a global cursor, and then check if it had a device cursor, which would
skip windows with only device cursors set, and unexpectedly set the
global cursor.
This avoids a bunch of policy problems with deciding how to lay
out the window menu under different WMs.
For now, we use the special event _GTK_SHOW_WINDOW_MENU, but we
hope to have this standardized in wm-spec quite soon, as KDE wants
it as well.
All the globals we care about should appear before doing anything
else, up-front, so a single round-trip after adding the registry
should be more than enough.
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.
Wayland's mechanism tells us all of our new states, rather than
telling us which ones were added and removed. Add a new private
interface so that we can simply specify the new states as a
bitfield directly rather than having to compute which ones were
added and removed.
Rendering doesn't do much about clipping drawing operations to the window shape,
although invalidation applies the shape to every window, leaving possibly trails
of "overrendered" content. So ensure the shape portions get invalidated too when
the window is moved/resized.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=728426
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
capabilities change. This also enables adding further capabilities
to handle eg. touch.

Get monitor on which the most of the window is located (nearest monitor if
window is not on screen), get its work area (area not occupied by taskbar or
any other bars) and use that for maxsize.
Previous default of 30000 meant that windows maximized onto full screen,
even covering the area where taskbar is.

...on Windows 8+ and when the system setting for non-Unicode programs do
not match the language version of Windows by falling back to using Pango.
This ensures that the correct font is used during these scenarios, so that
we minimize the risk of seeing garbled characters for texts that the system
code page does not support due to system peculiarties. There might be a
way to support gtk-font-name handling using the native Windows APIs
directly on Windows 8+, but that needs to be investigated.

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.
And the counterpart to unmaximize when dragging a maximized window, if
touch devices aren't going to use EWMH moveresize, having this one at least
makes things feel a bit less awkward.
https://bugzilla.gnome.org/show_bug.cgi?id=709914
Sadly, EWMH moveresize mechanism can't work with touch devices for two
reasons:
1) As a mutter implementation detail, the device is queried in order
to check whether the dragging button is still pressed. Touch devices
won't report the button 1 being pressed through pointer emulation.
2) Even bypassing that check, on X11 touch events are selected prior
to sequences being started, either through XISelectEvents or
XIGrabTouchBegin, no late registering through active grabs is allowed,
as WMs do on reaction to EWMH moveresize messages.
So for the time being, make touch devices fallback on emulated window
dragging, which at least allows for moving windows.

Add gdk_device_get_last_event_window(), and use to implement the window
tracking we need for synthesizing crossing events for sensitivity changes
and gtk grabs, rather than keeping the information in qdata and updating
it based when GTK+ gets events.

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.
We have a hack in the XSETTINGS code to substitute gtk-xft-dpi
with gdk-unscaled-dpi unless the screen has a fixed window scale,
in which case we just use gtk-xft-dpi.
But if the screen is changed to have a fixed window scale, then
the substituted value of gdk-unscaled-dpi will stick around until
the next (coincidental) change to XSETTINGS. To fix this, force
an immediate reread of the XSETTINGS property when
gdk_x11_display_set_window_scale() is used.
https://bugzilla.gnome.org/show_bug.cgi?id=725754
The point of GdkWindowImpl::get_root_coords is to translate the passed
in coordinates against the passed-in impl window. For a child window,
in fact, window->abs_x and window->abs_y already track the child
window's coordinates against the impl window.
If we pass in a child window, and backends don't explicitly get the impl
window from it, we'll double-count the child window.
Really, we should *always* be passing impl windows to backends, and
never child windows. However, I'm a bit worried for regressions late
in the cycle if we want to fix up the rest of the callers, like
gdk_window_get_geometry, so I'm only going to touch get_root_coords
for now after careful review of all the backends.
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.
