The Gtk.EventMotionController implementation in Gtk3 doesn't
emit the enter or leave signals when the mouse cursor enters
or leaves the associated widget.
After doing several tests, I discovered that the
gtk_event_controller_handle_event() method never receives any
of the events from the Gtk core, although they are generated
inside the core and enter-notify-event and leave-notify-event
signals are correctly emited.
This patch fixes it by adding the missing
gtk_widget_real_XXXXX_event handlers for enter and leave
event notifications.
Fix#7225
On Quartz the drawing region must be padded out to a multiple of 4 px
on regular displays and 8 px on Retina ones. Failing to do so used to
cause smearing on multi-monitor mixed-DPI systems but that seems to
have been fixed. There remains a visible flicker in animations.
Padding the GdkWindow width as well as the content frame and cairo
surface causes the frame clock to get frozen if multiple calls to
gtk_window_resize use the same size because
gdk_window_move_resize_internal sees a difference between the window
size and the requested size (the latter isn't padded out) and freezes updates. GdkQuartzNSWindow
windowDidResize is supposed to thaw them, but because the padded-out
width set for the frame doesn't change the window isn't resized and
the frame clock is never thawed.

dfea8c31d9 added a check for portal settings array length but what it really checks is the amount of dbus out arguments.
This commit makes it do what gtk4 does: really check array length.
Fixes: #3838
For GDK_WINDOWING_BROADWAY, GDK_WINDOWING_WIN32 and GDK_WINDOWING_QUARTZ
links open correctly. For example, for GDK_WINDOWING_WIN32 this happens
via gspawn-win32-helper.exe / gspawn-win32-helper-console.exe. If these
helpers are missing, a corresponding error message is displayed, see
e.g. gtk3-demo.exe => Links. So there are already other error messages
if something goes wrong. For gtk4 the behavior also occurs without
warning. In my view this warning is more confusing than helpful.
When drag-and-dropping a file from Nautilus to for example Firefox, this
does not work if the file is from a GVFS mounted source. The retrieved
URI with `g_file_get_uri()` still contains the protocol.
Instead, we can use `g_filename_to_uri()`, which resolves to the local
`file://...` URI instead.
A similar fix was applied to GTK4 on the sending side in commit
ea056d26.
The Wayland protocols around outputs are truly a disaster.
This is a backport of 854e40c60c0d32 from main in the hope
of getting monitor geometry to work across compositors.

If a `GtkMessageDialog` has a non-empty title set, use
that for the accessible name instead of a generic name
indicating the type of the message dialog, as the
window title is generally more informative, if set.
It also better matches the information presented
visually on screen (in the window title, task switchers,...)
and is in line with the handling for non-message-dialog
windows.
This can easily be tested with the "Dialogs and
Message Boxes" sample from gtk3-demo when setting
a title for the message dialog in there like this:
diff --git a/demos/gtk-demo/dialog.c b/demos/gtk-demo/dialog.c
index 0eb1c62397..53fb7f8b0e 100644
--- a/demos/gtk-demo/dialog.c

Extract the existing logic to set an accessible name for the
`GtkMessageDialog` based on the message type from `setup_type`
to a new helper function `update_accessible_name`.
That helper function will be reused and extended in a follow-up
commit.
Bug Description: In a GTK+ application with a menu bar, clicking the
menu item displays a dialog. However, when the user opens this dialog
and drags the parent window's menu bar with the cursor, the dialog
gets moved.
Issue: When _gtk_gesture_update_point calls the _update_widget_coordinates
function, the local variables x and y are not explicitly initialized, leading
to arbitrary values. For instance, in my case, x was 32767 and y was
-145750164 . These values are used in the subsequent call to
gtk_widget_translate_coordinates. In gtk_widget_translate_coordinates,
if ancestor is NULL, the function returns FALSE, and dest_x and dest_y
are not updated. The incorrect values of x and y cause data->widget_x
and data->widget_y to be incorrect, ultimately leading to abnormal
x and y values in the gtk_gesture_drag_update function.
To avoid this, we should set x and y to values clearly outside the widget.
