Using UpdateLayeredWindow() on iconic windows brings them *back* from
their iconic (minimized) state. That is bad.
As a precaution, also don't use SetWindowPos() on iconic windows.
This means that iconic windows can't be moved. That is fixable
by using SetWindowPlacement(), but there is no pressing need to do so,
as there are very few cases when windows need to be moved while minimized.

The way gdk_drag_status() may be called multiple times during the
processing of drag and drop events throughout the widget hierarchy
brings some superfluous messaging going in, esp. when it's the last
request the one we want to honor, yet we emit messaging requests on
all.
This is barely appreciable in the X11 backend, but due to the design
of the wayland protocol, quick series of changes like this it have
some self-amplificating consequences which may end up flooding the
connection.
We can delegate this to a late "commit" call, performed within GDK
event management. This way gdk_drag_status() calls may be cached
and only result in windowing messaging once per ::drag-motion or
::drag-data-received event. Emitting the final status will also
avoid spurious action changes on the compositor and the other peer.

was meant to find the child gdk window at coordinates root_x and root_y.
These 4 lines had 2 bugs:
1) x = x - root_x (same for y) is wrong, it should be x = root_x - x
2) gdk_device_get_window_at_position() does not give you the window
at position x and y. It gives you the window under the device
(mouse pointer) and the returns the device coordinates in x and y.

MacOS provides the NSEventTypeMagnify which is very similar to the

A gtk_surface.present request was added to gtk_surface which takes

The gtk_shell protocol used some half baked unstable protocol semantics
that worked by only allowing binding the exact version of the
interface. This hack is a bit too confusing and it makes it impossible
to do any compatible changes without breaking things.
So, instead rename it to include a number in the interface names. This
way we can add requests and events without causing compatibility issues,
and we can later remove requests and events by bumping the number in
the interface names.

This request actually means nothing to the upper GDK layers,
we used to preempt a GDK_SELECTION_REQUEST event, but this is too
eager, and not like things work in X11.
Originally in wayland, this event may be used for feedback purposes.
We however don't perform any mimetype-based feedback, so we can
safely ignored.
This makes data_source_send() the only place where we actually
trigger GDK_SELECTION_REQUEST, this one is conceptually the same
than the X11 selection request event.

Toplevels are now true layered windows that are moved,
resized and repainted via UpdateLayeredWindow() API call.
This achieves transparency without any extra effort,
and prevents window size and window contents desychronization
(bug 761629).
This also changes the way CSD windows are detected. We now
use window decorations to detect CSDiness of a window,
and to decide whether a window should be layered (CSD windows should
be) or not.
Decorations are now stored in the window implementation,
not as a quark-based property of the window-as-gobject.

Normally works only on CSD windows, non-CSD windows continue
to use WM modal loop for drag-resizing and drag-moving. However,
if it is activated on non-CSD windows, it does work.
Has the advantage of being completely immune to AeroSnap.
AeroSnap only worked partially on CSD windows, with the only part
that worked being "don't let users drag window titlebar outside of
the desktop". Now AeroSnap doesn't work on windows moved by
this code at all, which is good, since they currently don't work
well with it due to the way shadows are drawn.
It's possible to also re-implement AeroSnap (or something similar),
but that is a story for another commit.
This code was originally intended to fix the problem of window
size and window contents desynchronization, but failed to achieve
that result in the end. Nevertheless, it serves as a foundation for
other changes to the way window resizing works.

deliver_key_event is sometimes called from a timeout handler and

we're going to need to call it directly in other parts of the code
where the return value would be relevant and handling TRUE, would
require adding redundant code.
Instead, this commit just changes the code to always reset the timer
manually, and never rely on glib's ability to automatically reset
the timer by returning TRUE. This makes the code smaller, too, since
there's less special casing required.

There is no point in attaching and then committing the same buffer if
there was no damage. This will also make us do less unnecessary backfill
read backs, for the cases where we paint with an empty paint region.
https://bugzilla.gnome.org/show_bug.cgi?id=762120
If a after-paint was scheduled but nothing was painted, for example when
the it was scheduled by a subsurface wanting to update its position,
we'd still try to read back from the backfill cairo surface and update
the committed cairo surface reference even though no buffer was
attached.
Fix this by adding a new state, 'pending_buffer_attached', which is only
true if a buffer was attached during frame. Only when this is true will
the backfill be read back and the committed cairo surface reference be
updated.

Right now we use one buffer for both staged changes (freshly painted
changes waiting for the frame clock to send to the compositor) and
committed changes (changes actively being read by the compositor
process). This creates a problem in the event we need to stage updates
at the same time the compositor is processing committed updates: we
can't change what the compositor is actively processing.
The current solution for handling this contention is to allocate a
temporary buffer on the spot at the time the updates are staged, and to
copy that buffer back to the shared buffer later. The problem, though,
is that the copy to the shared buffer currently happens as soon as
the updates are finished being staged, not when the shared buffer is
done being processed by the compositor.
In order to address that problem, this commit changes the code to always
stage changes to a dedicated staging buffer. The staging buffer is
used exclusively by the client until the client is done with it, and then
once that staging buffer is committed, the client never writes to that
buffer again. If the client needs to stage new updates, it allocates a
brand new staging buffer, draws to it, and back fills the undrawn parts
of the buffer from a copy of the contents of the committed buffer.
As an optimization, the compositor has the option of releasing the
committed buffer back to the client. If it does so before the client
needs to stage new updates, then the client will reuse the buffer
for staging future updates. This optimization prevents having to allocate
a new staging buffer and the associated cost of back filling
that new buffer with a readback of the committed buffer.
https://bugzilla.gnome.org/show_bug.cgi?id=761312
Right now we handle buffer releases coming from the
compositor in a central place. We add a listener when
first creating the shared buffers.
This is problematic because a buffer can only have
one listener on it at once so users of the buffer
can't get notified when it's released.
This commit moves the buffer listener code from the
centrally managed display code to the cursor and window
code.
https://bugzilla.gnome.org/show_bug.cgi?id=761312
The client and compositor share access to the window
pixel buffers. After the client hands off (commits)
the buffer to the compositor it's not supposed to write
to it again until it's released by the compositor.
The code tries to deal with this contention by allocating
a temporary buffer and using that in the mean time. This
temporary buffer is allocated by a higher layer of the code
when begin_paint returns TRUE. Unfortunately, that layer of
the code has no idea when the buffer is released, so it ends
up blitting the temporary buffer back to the shared buffer
prematurely.
This commit changes begin_paint to always return FALSE.
A future commit will address the contention problem in
a different way.

Temp windows without parent are used frequently in our testsuite;
using g_warning on them causes the tests to fail, which is not
useful. Reduce the warning to a g_message.
Presently, Gtk will only send a startup notification completion message
for the first window that is shown. This is not good for the case of
GtkApplication, where we are expected to participate in
startup-notification for all windows.
We have avoided this problem by manually emitting the startup complete
message from after_emit in GtkApplication.
Unfortunately, this causes problems for windows that are shown with a
delay. It is also a dirty hack.
The reason for the original behaviour is simple: there is a static
boolean in gtkwindow.c which controls it. We remove this.
Instead, clear the startup notification ID stored in GDK when sending
the completion message. GtkApplication will re-set this the next time
an event comes in which needs startup-notification handling. In the
non-GtkApplication case, newly shown windows will still not send the
message, since the cookie will have been cleared.
Finally, we remove the hack from GtkApplication's after_emit.
This will probably cause some regressions in terms of lingering startup
notification messages. The correct solution here is to always use
gtk_window_present(), including when merely opening a new document (with
a new tab, for example).

This was a thinko - what we sometimes do for signal names is to
use I_() to intern them (to avoid a strdup), but I_() is not

It looks like the gnome-continuous headers haven't quite
caught up yet, so try __NR_memfd_create instead.
If that doesn't work, i'll likely just add in a fallback

create_shm_pool doesn't need the width or height, it just needs

This commit drops the width and height parameters and makes the

https://bugzilla.gnome.org/show_bug.cgi?id=760897
Right now, we assume the stride for the image surface needs to
be 4 byte aligned. This is, in fact, true, but it's better to
ask cairo for the alignment requirement directly rather than
assume we know the alignment rules.

create_shm_pool unlinks the temporary file a little,
too late. It should be unlinked before ftruncate()

could muck with it

These functions will be automatically called by the windowing backend.
The usual hooks to run this from in gtk/ shouldn't even happen, but
it is worth to document which calls are expected and which aren't.
If the grab window is destroyed the grab will be implicitly removed,
although we won't get GdkSeat:ungrab called in order to clear our
internal window<->seat relation entirely. Setting a weak ref will
nullify the pointer we keep on the seat to the window, avoiding the
expected crashes.
Due to implicit grabs, we basically can guarantee that the pointer
won't have any buttons pressed at the time of wl_pointer.enter.
Seems like a good place to unset any button modifiers that might
have been left stale by compositor grabs.
This includes managing input events and source-side DND events,
as well as setting the appropriate cursor and emitting the signals
that are expected in this mode of operation.
This function (most similar to gtk_drag_get_cursor() helps figure out
the right cursor that applies to a given action. To be used by the
various backends.
We've traditionally left GTK+ to handle the input side of things,
letting GDK only manage the windowing-specific messaging. This
way of splitting responsibilities is not compatible however with
some backends, we must fold then input management at the DnD stage
into GDK (and backends) domain.
The gdk_drag_context_manage_dnd() call is meant to be the entry
point for this mode of operation, if the drag and drop operation
becomes managed, the caller (i.e. gtkdnd.c) doesn't need to perform
grabs, nor manage input events itself.
As a consequence of this, different aspects now belong to the
backend GdkDragContext implementation:
- Because the caller doesn't see keyboard events anymore,
keyboard navigation must be managed in GDK, so is the decision
of the current action based on modifiers/button pressed.
- Because the caller won't see input events in general, the lifetime
of the drag and drop operation is now communicated through the
::drop-performed, ::dnd-finished and ::cancel events
- Because the caller doesn't participate anymore on the action
being chosen, the pointer cursor must be set by the backend.
The caller is rather notified of the final action through the
::action signal.
The caller is still responsible of dealing with the corresponding
GdkSelection, ensuring its ownership and communicating the supported
mimetypes.
And use it to handle kinetic scrolling in the GtkScrolledWindow.
However, dropping the delta check causes the X11-based kinetic
scroll to break since we don't have the stop event here. Correct handling of
xf86-input-libinput-based scroll events is still being discussed.
https://bugzilla.gnome.org/show_bug.cgi?id=756729
This adds support for the new wl_pointer events available in v5.
The wl_pointer.axis_source events can be ignored for the purposes here, the
main reason they exist is so that the combination of axis_source=finger and
axis_stop triggers kinetic scrolling. We don't need to care about the source,
axis_stop is enough for us to tell us when we're scrolling.
The wl_pointer.frame events group events together and is intended as a
mechanism to coalesce events together. This for example allows us to now
send a single GTK scroll event for a diagonal scroll. Previously, the two
wl_pointer.axis events had to be handled separately.
The wl_pointer.axis_discrete event sends mouse wheel clicks where
appropriate, and is translated into up/down/left/right scroll events.

which, in Adwaita, should have no shadow and are CSD-ish (which means
that tooltip window is larger than it looks, and WM draws the shadow
only on the outside, leaving a gap between the visible tooltip edge and
the shadow).

When a cursor is specified in gdk_seat_grab(), the cursor is reverted as
soon as the pointer enters or leaves another window.
To avoid this issue, store the grab cursor separately, so we force-apply
it in ::set_window_cursor(). Also, unset early the seat info from the
window on gdk_seat_ungrab(), so the next time switch_to_pointer_grab()
happens we end up picking the cursor set for the window underneath the
pointer window.
Based on a patch by Olivier Fourdan <ofourdan@redhat.com>.

We are getting the mime data destroy notify called when we
destroy the surface in finalize. Trying to set the XSync counters
at this time is a) pointless and b) yielding an X error because
the counters have already been destroyed.
To avoid this, unhook the damage tracking before destroying
the surface.

We are setting mime data with a destroy notify on the cairo
surface to get notified when cairo registers damage for the
surface (in that case, it clears the mime data, calling the
destroy notify). Unfortunately, the destroy notify is also
called when we remove the mime data ourselves, which was
not intentional.
Use a flag in the window impl struct to ignore the callback
when we are clearing the hook.
Instead of creating an intermediate pixbuf, just render
the window surface onto the new surface. Doing things this
way lets us avoid the cairo_surface_mark_dirty() call in
gdk_pixbuf_get_from_window(), which is not generally safe
to call on 'random' surfaces - it asserts that the surface
has no mime data attached, and the X11 backend uses mime
data for damage tracking purposes...
We destroy the widget that is wrapped around the drag window
when the object data on the drag context gets cleared. Destroying
the window before that happens leads to unpleasantries. E.g. we may
try to access the frame clock, which doesn't exist anymore, and
things go downhill from there. So, keep the window alive for
a little longer.

X11 has the notions of "transient for group", and while it's an ICCCM
violation, it's commonly used and documented that a window manager
would treat a window with transient_for set to None to transient for all
windows of its group.
gtk uses this when an application sets a dialog type window but does not
specify an explicit transient.
While this works on X11, there is no such thing as groups in Wayland and
the closest equivalent which is set_parent() in xdg-shell takes only one
parent. This is what is used for modal dialogs.
To get something similar in behavior to what is available on X11, a
solution is to update the parent() of the dialogs without transient when
the active surface changes.

Quite a few applications use GTK_WINDOW_POPUP to create various
temporary windows and place then on screen. That works fine on X11 but
on Wayland there is no global coordinate system for regular surfaces.
If the application is using a gdk temp window and set a parent with
gtk_window_transient_for(), the gdk wayland backend has all it needs to
create a subsurface that can be placed at will by the application.

Always returning a left_ptr if we can't find anything better
broke firefox application-specific fallback for missing cursors.
Keep that working by only doing the fallback for the CSS cursor
names, not for things like hashes.

Functions requiring CoInitialize are called just in two places:
- the filechooser thread which calls its own CoInitializeEx
- the dnd code
Moving CoInitialize in the dnd specific init is cleaner and
we can pair it with the corresponding CoUninitialize since
CoUninitialize should be called as many times as CoInitialize.
Note that it is ok to call this function multiple times, so it
will not break if another codepath will need it in the future.
The patch also replaces the deprecated CoInitialize with the
equivalent call to CoInitializeEx (already used in the filechooser).
In most places, we can do with the pointer/keyboard of the default seat
instead of the client pointer. We can also remove some code from
gdk_input_init() because we know for sure there's no floating devices to
care about here.
There's places where we still need to deal with floating devices, which are
unseen by seats. Ignore deprecations and keep using GdkDeviceManager until
we can forget about floating devices.

There's places where we don't set a seat yet, plus the places
outside GTK+ where events are created, we should warn and fall
back to the master device seat with these.
Gdk Wayland backend walks up the transient windows tree, but does not
check for cycles when doing so.
As a result, if two or more windows are transient to each other, the
Wayland gdk backend will enter an infinite loop.
While this is clearly a bug in the application, gtk+/gdk should be more
robust and handle such errors more gracefully.
To avoid looping infinitely at various point in the code, check for a
possible loop when setting the transient relationship and deny the
request to set a window transient for another if that would create a
loop.

gdk_pixbuf_get_from_window() paints the given window onto a new cairo
surface. Create that new surface with the same device scale as the
window so that the result is not scaled down on hidpi screens.
This is similar to 657a43e (which was reverted), but doesn't modify the
behavior of gdk_pixbuf_get_from_surface().

Our actions on ::device-removed only actually applied to master
pointers, so listening to GdkDisplay::seat-removed and operating
on the seat pointer is equivalent.
