After checking for rendered_surface, the call to gtk_css_node_get_style
can invalidate the style and result in rendered_surface being set to
NULL. This was result in some icon views appearing blank on
Endless OS on armv7hl, and this error:
Gtk-CRITICAL **: gtk_css_style_render_icon_surface: assertion 'surface != NULL' failed
Call gtk_css_node_get_style earlier to ensure we always pass a valid
surface to gtk_css_style_render_icon_surface.

This was meant to be silenced unless expicitly requested but
G_ENABLE_DEBUG is defined by default unless --disable-debug is passed to
configure, so use G_ENABLE_CONSISTENCY_CHECKS instead which is only
defined if --enable-debug is explicitly passed.
add circle objects to the injected style for recoloring.
Should avoid randomly colored symbolic icon bits when circles are
in the mix as in network-vpn-acquiring-symbolic for example.
Otherwise, with CSD, we could have a discrepancy where gtk uses the
right values for the shadows whereas the gdk backend still uses the old
values, leading in some cases to invalid or negative min size being
computed (which, in Wayland, leads a protocol error).
https://bugzilla.gnome.org/show_bug.cgi?id=771561
The main corpus of the documentation for gtk_window_get_size() is still
full of X11-isms, so we should port it to something that is more
backend-agnostic. Additionally, having some examples would be nice for
application authors looking at a way to appropriately use this function.
If somebody decides to use gtk_widget_set_double_buffered() in the
middle of a draw() then there's the risk of calling end_draw_frame()
with an invalid pointer.
Some overeager compilers may warn about the double_buffered bit field
changing values and leading to a potentially uninitialized variable.
In order to avoid compiler warnings or crashes, we can simply store the
value of the double_buffered bit field at the beginning of the rendering
and use that instead of the actual bit field.

Not all occurrences of this warning can be fixed today, so put it behind
a G_ENABLE_DEBUG flag since it still shows legitimate problems even if
some of them are false positives.
The fix for bug 767468 had some unintended side-effects. This is
an attempt at doing the same fix (don't grab focus when we are
grab-shadowed), while avoiding the breakage, by using GTK+'s
internal tracking for grab-shadowed-ness.

Analogous to (un)mount operation, we now keep a reference around
during the ongoing operation and make use of the destroyed flag
to check if we are still alive or if we have been cancelled as
a result of the widget being destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
Since we hold on to a reference during (un)mount operations, we
don't trigger the cancellation of operations in finalize anymore.
Instead we now override the GtkWidget's destroy() and cancel any
ongoing operations there.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
The current code wrongly assumes that cancellation can only happen
as a result widget finalization, and consequentially does not
properly recover from it. Therefore if the operation is cancelled
as a result of user interaction, the entry is will stay disabled
and the spinner will keep spinning. This is fixed by removal of
the early bail out in case of cancellation.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
During mount and unmount opertions we keep a reference to the
GtkPlacesView around, so we have a valid view for the callback
code, even in the case that othe external references have been
dropped (i.e. the containing window gets destroyed).

This reverts commit 6af5033386.
Scrolled window behavior of propagating child natural sizes
has now been made optional, so there is no need to work around
this by setting a hard coded maximum content height anymore.
In gtkscrolledwindow.c, the return type of _get_propagate_natural_width()
and _get_propagate_natural_height() were accidentally gint instead of
gboolean, fixed to match the type correctly declared in the header file.
The code always assumed that getting a row at a certain 'y' was
possible but if the list box has more empty space than rows then a
valid row may not be retrieved.
https://bugzilla.gnome.org/show_bug.cgi?id=770703
- while we don't use steppers anymore, for some reason they are still
defined in the theme and if you sacrifice a chicken and jump on one
leg at full moon, you can enable them.

Since we're using _get_rect_coords in size-allocate when allocating the
size of the child widget, use the newly introduced _get_rect_for_size to
calculate the difference between the passed size_for and the one we're
supposed to pass on to the child widget.
When calculating the requested size of a popover, we need to do the
exact same same thing _get_rect_coords did, but not for the
current popopver allocation. Add _get_rect_for_size that can be used for
this purpose
Making propagation of child natural sizes mandatory (or default, even) was
evidently a mistake as this causes dynamic content in a scrolled window
to resize it's parent when the scrolled window is competing for space
with an adjacent widget.
This patch instead adds API to control whether natural width and
height of the child should be propagated through the scrolled windows
size requests.
We were using __VOID for the SHOW_OTHER_LOCATION signal that
uses flags named SHOR_OTHER_LOCATION_WITH_FLAGS.
However, if a signal uses flags the marshal needs to use __FLAGS.
This patch addresses this using VOID__FLAGS as the marshaler parameter.
Thanks to Jan Steffens for pointing this out.

This GdkEventController is a helper object to handle pad events,
it allows setting a mapping to action names, to be triggered in
the given action group.
In order to help on places where advanced mapping/configurability
of pad features is not desirable, this controller also allows
passing a NULL pad device, meaning it will listen on all pads,
and/or passing -1 on mode/index, so an action applies to all
modes/features (eg. strips/rings).

The effect of transitions-enabled=true can now be
achieved using gtk_popover_popup/popdown and the effect
of transitions-enabled=false can be achieved using
gtk_widget_show/hide.
https://bugzilla.gnome.org/show_bug.cgi?id=769706
Since not chaining up in gtk_widget_show/gtk_widget_hide is not allowed,
we can't just implicitly delay the hiding in GtkPopover's hide
implementation. Fix this by introducing gtk_popover_popup() and
gtk_popover_popdown() to show or hide a popover with transition and
revert GtkPopover's show/hide implementation to apply their effect
without the transition.

The GtkHeaderBar gadget implementation was subtly broken: it called
gtk_widget_set_allocation both in gtk_header_bar_size_allocate (with
the actual allocation) and in gtk_header_bar_allocate_contents (with
the content allocation of the main gadget). Dropping the second call
fixes the render node conversion for GtkHeaderBar.
:toggled is triggered on :clicked, so using :toggled lead to the menu
to be popped up at the same time, while allowing to use the toggle state
and avoiding any need to a hack to prevent recursion, which somehow
wasn't enough for double emission of GtkMenuToolButton:show-popup.

Pick the W32 API for possible deadkey+<something> combinations
and prefer these to other sources of deadkey combos.
Specifically, if W32 API supports at least one combo for a particular
deadkey, only use that data and do not attempt to do other, unsupported
combinations, even if they make sense otherwise.
This is needed to, for example, correctly support US-International
keyboard layout, which produces a combined character for <' + a>
combo, but not for <' + s>, for example.
This is achieved by stashing all the deadkeys that we find in
an array, then doing extra loop through all virtual key codes and
trying to combine them with each of these deadkeys. Any combinations
that produce a single character are cached for later use.
In GTK Simple IM context, call a new GDK W32 function to do a lookup
on that cached combination table early on, among the "special cases"
(which are now partially obsolete).
A limitation of this code is that combinations with more than
one deadkey are not supported, except for combinations that consist
entirely of 2 known deadkeys. The upshot is that lookups should
be relatively fast, as deadkey array stays small and the combination
tree stays shallow.
Note that the use of ToUnicodeEx() seems suboptimal, as it should
be possible to just load a keyboard library (KBD*.DLL) manually
and obtain and use its key table directly. However, that is much more
complicated and would result in a significant rewrite of gdkkeys-win32.
The code from this commit, though hacky, is a direct addition to
existing code and should cover vast majority of the use-cases.

The new positioning-related properties had some quality of
implementation issues, such as incorrect initial values and
excessive change notification. This broke the notify test.
It tried to set the expand state if either xexpand/yexpand where true.
Due to a missing queue_compute_expand when adding a child it actually
only computed the expand state in case a child queued after being added
or in case a child had the expand property set (see optimization in
gtk_widget_set_parent)
In my case this broke layouts as a child of GtkCombBox started setting
an exand flag with 3.20 which queued a compute_expand, which in turn
propagated an expand child props set for a cell in the same table up
and overrode the expand child prop of a parent GtkBox.
This removes the custom compute_expand implementation to match the
behaviour of GtkBox (don't propagate child prop expand flags
but let child expand flags override the child props) and not get random
expand behaviour depending on whether and when child widgets set their
expand state.

Introduce a private API meant for abstracting how to get a handle
of a window that can be shared with other processes. The API is
async, since some implementations will require that. Currently,
only X11 is supported, which doesn't.
Based on a patch by Jonas Adahl.
When there's no useful shortcut accelerator set,
GtkShortcutLabel doesn't show any useful information.
To work around that, add a new property to set the
text to be displayed when there's no accelerator
available.
https://bugzilla.gnome.org/show_bug.cgi?id=769205
GtkShortcutLabel is a widget that displays a single
shortcut accelerator or gesture in the user interface,
and is currently used by the shortcuts window.
This widget, however, has public value as other applications
also may want to expose their own shortcuts. For instance,
it'll be useful for the Keyboard panel on Control Center and
the new shortcut editor in Pitivi, among others.
This patch exposes GtkShortcutLabel as a public widget,
and adds the necessary documentation.

Scroll history must refer to a timespan for the values to be valid, otherwise
we return FALSE, in this case the stored event(s) should be discarded anyway.
It could be the case that the last scroll event is received long after any
previous scroll event, in this case the last scroll event discards all "old"
scroll events, and scroll_history_finish() returns FALSE because there's no
time/offset deltas in the scroll history.
This is desired so we don't trigger the deceleration effect if there was no
effective velocity, we still must reset the installed scroll cursor, so take
it out of this if() condition.
I thought I needed ot rearrange the ordering of the animation-direction
values for the parser, overlooking the fact that we already parse them
backwards to address this very problem.
