If we bind to a global with an higher version than implemented, or
we make requests that appeared in a later version, we would get
fatal wayland errors.

With the introduction of the use of buffer scaling in ed4fcee4ct we
must request version 3 of the compositor as that is the version of the
surface interface that adds this new functionality. See the following

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.
This lets use use a scaled Xft/DPI for old apps while not
blowing up the size of scaled windows. Only apps supporting
Gdk/WindowScaleFactor should supprt Gdk/UnscaledDPI.
If you set GDK_SCALE=2 in the environment then all windows will be
scaled by 2. Its not an ideal solution as it doesn't handle
multi-monitors at different scales, and only affects gtk apps.
But it is a good starting points and will help a lot on HiDPI
laptops.
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 a cairo_surface for a window has a device scale set we need
to respect this when creating a similar window. I.e. we want
to then automatically create a larger window which inherits
the scale from the original.
We also need to calculate a different device_offset if there
is a device_scale set.
-Don't include unistd.h unconditionally as it's not available in Visual
Studio, but include io.h where necessary.
-Avoid C99isms, and use _chsize_s in place of ftruncate when unistd.h is
not available (as in the case of Visual Studio)
Only look at "impl" windows in gdk_window_process_updates_with_mode()
since these are the only ones we care about. This avoids a lot of
unnecessary calls to g_list_copy() and g_object_ref().
We don't want to recurse into children that are clipped, as that is
wasted work. We handle this by moving the empty check to the top
of the function and only using the clipped region everywhere.
Move the call to gdk_x11_atom_to_xatom_for_display() outside of the
search loop in gdk_x11_screen_supports_net_wm_hint(). In my test case
(running Audacious for about a minute), this reduced the total number of
hash table lookups performed from 370,000 to 230,000.

and not on each keystroke, which for some IMs apparently caused a full
update on each keystroke, not just a check for changes. Patch from
Takuro Ashie, bug #698183.
window_type_hint_to_level(): applied patch from Paul Davis which moves
dialogs to NSFloatingWindowLevel. This is not quite the perfect
solution, but it's a pragmatic fix that makes apps which have both
window types much more usable, and prevents dialog from disappearing
under an application's main window.
(cherry picked from commit 59d49e1566)
Include config.h first so that _GDK_EXTERN may be defined once
and only once during the build, so that we do not get warnings/
errors for macro redefinition.

Include gdkwin32.h (which includes gdkprivate-win32.h and gdkwin32cursor.h
during the build of GDK-Win32) so that
gdk_win32_icon_to_pixbuf_libgtk_only() and
gdk_win32_pixbuf_to_hicon_libgtk_only() get exported, so that the GTK
DLL can link correctly.
Calling XIQueryPointer() on a slave device is going to trigger a
BadDevice X error. So in case we query a slave device state, ask the
master device instead.

Add missing check in gdk_x11_device_manager_xi2_get_window(), returning
NULL if no valid XI2Event* has been found. Calling code seems to be
prepared to handle NULLs coming from this function, so it should be
safe enough (e.g. check gdk_event_source_get_filter_window()).

We don't track the full clip for each window anymore, as this
is not useful when no windows are opaque. However, we still
need the full clip for the shape, so its calculated manually.
However, it was previously only recalculated when the clip changes
which doesn't correctly handle the case of a sibling geometry changing.
So, instead of doing this directly when geometry changes we just
set a bit in the toplevel whenever some window geometry changes, and
we then handle this in process_updates, updating the shape for all
native windows. This should be ok performance-wise because we don't
expect a lot of native children.
This is left over from an old effort to bundle gtk and its dependencies
into a Mac OS X Framework. The effort was more or less successful but
proved difficult to maintain and impractical to use because gtk programs
don't use the special Framework include syntax.
In the ancient X days you could have Xservers that had multiple active windows, like
one truecolor and one 8bit palette. Then most apps ran in 8bpp but a single window
would use truecolor. This is done by specifying different visuals for the windows.
To make this work we ensured that a window with a visual different from its parent
gets a native subwindow, so that X can tell the hardware to do its magic.
These days the only real time we get two different visual is when one is a rgba visual
and the other is not. So, the code to check this doesn't really do anything but
get in the way when someone accidentally manages to not get a rgba visual on
a child window (see bb7054b508). So, to avoid
such errors we just remove the "different visual than parent" check.
We need to send exposes for all native windows, even the ones
without an exposure mask set, because otherwise non-native
children of the native window with an exposure mask will
not be drawn.
This removes the typechecks in GDK_WINDOW_TYPE and GDK_WINDOW_DESTROYED. These
are only used internally in gdkwindow.c and gdkdisplay.c anyway, and these
functions check for typesafety of arguments on function entry.
This function returns all the children that has a specific user_data set.
This is used a lot in the new GtkWidget drawing code and doing
it this way is faster than getting every child and calling get_user_data
on each (which was a non-neglible part of the profiles). Additionally it
also allows use to use some kind of hashtable to make this operation even
faster if needed in the future.
This lets you register callbacks for when child widgets invalidate
areas of the window read it and/or change it.
For instance, this lets you do rendering effects and keeping offscreen
caches uptodate.
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.
