This is so we always have the latest information given by XRandR (or other), and not
rely on Core protocol information that might not have been updated yet.
This is specially visible when a monitor is connected (less frequent) or disconnected
(much more frequent), callbacks on GdkScreen::monitors-changed that call
gdk_screen_get_width/height() could get the screen size previous to the monitor
rearrangement.
So in order to fix this, keep track of the latest monitors information, and calculate
the bounding box in order to know the screen size.

Scroll valuators were being just appended again and again, leading
to 1) a growing memory issue anytime a device changed 2) the first
scroll valuators to stay permanent on the application lifetime, as
the first stored valuators would always match.
https://bugzilla.gnome.org/show_bug.cgi?id=705203
Passive grabs may take pointer focus out of the application, even though
the pointer didn't leave the window, but those events still trigger resetting
of the scroll axes. This is most visible with compiz, and possibly other
reparenting WMs, where passive grabs happen on the WM-managed window that
is a parent of the application toplevel.
As it is not possible to have scrolling happening on the timespan a passive
grab takes action, it is entirely safe for GTK+ to assume none happened if
it gets a crossing event of that nature.
https://bugzilla.gnome.org/show_bug.cgi?id=699574#c33
This information will be useful in case someone stumbles on a situation
similar to https://bugzilla.gnome.org/show_bug.cgi?id=699574, so we can
figure out where do the crossing events come from or go to easily.
It's been reported in several applications that scrolling feels jerky
since commit cc7b3985b3.
Investigation reported that the combination of passive 4-7 button grabs
on the toplevel and the presence of native subwindows might trigger
too often crossing events from the child window to the toplevel and
back as scroll "buttons" trigger the passive grab. Those crossing events
would reset the scroll valuators rendering scrolling from jerky on
touchpads (where there's intermediate smooth events between the emulated
button ones) to ineffective on regular mouse wheels (where the crossing
event would reset the valuators right before the single smooth scroll
event we get is delivered)
So, only reset scroll valuators when the pointer enters the toplevel
(we only care about this when the pointer is on the window after it's
been possibly scrolling somewhere else), and it doesn't come from an
inferior.
The situations where this happened varied though, the native subwindow
could be one created explicitly by the application, or created indirectly
through gdk_window_ensure_native(). The latter was mainly the case for
evolution (through gtk_selection_set_owner()) and any GtkScrolledWindow
under the oxygen-gtk3 theme (through gdk_window_set_composited())

Add a GtkSetting for whether the desktop shell is showing the desktop
folder icons.
This is on by default because most desktop shells do show the icons on
the desktop. We already have a patch in gnome-settings-daemon to bind
this to the org.gnome.desktop.background show-desktop-icons GSettings
key which is off by default on GNOME.

We add a custom im module for broadway that calls some broadway
specific APIs to show/hide the keyboard on focus in/out. We then forward this
to the browser, and on the ipad we focus an input field to activate
the keyboard.
The broadway backend would move the focus from one window to another based on
where the mouse was (i.e. 'focus-follows-mouse' approach). Handling the focus
this wait didn't play well with widgets which rely on focus-in-event and
focus-out-event, like the GtkEntry when using a completion popup window, see
e.g:
https://bugzilla.gnome.org/show_bug.cgi?id=708984
So instead, setup broadway to require a click in a window to move the focus
(i.e. 'click-to-focus' approach):
* The implicit GDK_FOCUS_CHANGE events that were generated upon reception of
BROADWAY_EVENT_ENTER or BROADWAY_EVENT_LEAVE are removed.
* The broadway daemon will now keep track of which is the focused window
* Whenever the daemon detects an incoming BROADWAY_EVENT_BUTTON_PRESS, it will
trigger the focused window switch, which sends a new BROADWAY_EVENT_FOCUS to
the client, specifying which windows holds the focus.
* Upon reception of a BROADWAY_EVENT_FOCUS, the client will generate a new
GDK_FOCUS_CHANGE.
* gdk_broadway_window_focus() was also implemented, which now requests the
focus to the broadway server using a new BROADWAY_REQUEST_FOCUS_WINDOW.
This is based on an initial patch from Aleksander Morgado <aleksander@lanedo.com>.
If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.
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.

Although I can't find explicit documentation for clipboard pointer, it
seems to be possible to modify clibpoard memory without side-effects.

"The global and local functions are supported for porting from 16-bit
code, or for maintaining source code compatibility with 16-bit
Windows. Starting with 32-bit Windows, the global and local functions
are implemented as wrapper functions that call the corresponding heap
functions using a handle to the process's default heap."
"Memory objects allocated by GlobalAlloc and LocalAlloc are in private,
committed pages with read/write access that cannot be accessed by other
processes. Memory allocated by using GlobalAlloc with GMEM_DDESHARE is
not actually shared globally as it is in 16-bit Windows. This value has
no effect and is available only for compatibility. "

Setting event compression to false will allow inter-frame

This is based on the rolling hashes code from
http://cgit.freedesktop.org/~krh/weston/log/?h=remote
It works by incrementally calculating hashes for every 32x32 block
in each frame sent, and then refering back to such blocks when
encoding the next frame. This means we detect when a block matches
an existing block in the previous frame in a different position.
This is great for detecting scrolling, which we need now that
the gdk level scrolling is neutered.

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
Discovered via a crash because b's (dest's) toplevel was NULL;
ensuring that the dest is actually a GdkWindow or setting b to NULL
prevents that path from being taken.
If we're going to run off the end due to an invalid message,
we're going to run off the end. We'll protect this by doing
proper bounds checking in the future, but the malloc gives
us nothing for now.
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.

Pass the master device instead if the last slave is NULL. This is

The version of device scale that landed in upstream cairo
master already inherits the device scale in cairo_create_similar,
so no need to do that in gtk anymore.
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.

Due to the work on gdk_cursor_new_from_surface (commit b2113b73),
get_cursor_for_pixbuf() in GdkDisplayClass was converted to
get_cursor_for_surface(), which means the GDK Win32 backend needs to be

This lets you force a specific window scale, this is needed

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

Xsun is no longer shipped to customers, and Oracle/Sun's Xorg distribution

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.

Plug windows weren't redrawing properly because the embedded
window was expecting to get messages for each frame from the
compositor, but the compositor doesn't know about embedded

extending XEMBED to handle frame sync isn't interesting
at this point.

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

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

Only look at "impl" windows in gdk_window_process_updates_with_mode()

We don't want to recurse into children that are clipped, as that is

window_type_hint_to_level(): applied patch from Paul Davis which moves

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.
