08d59d3f68 docs: Add "Accessibility" section to various widgets
There are a few widgets that gained an accessible role, which means
adding an "Accessibility" section in their description.

40c0826921 a11y: Mark more containers as structural elements
Widgets that just provide grouping and layout to other widgets should
not be relevant to the accessible tree.

8dad615f04 gtk: Remove unused header include
gtkcssnodeprivate.h was mainly used for repositioning CSS nodes in
gadgets, and gadgets are gone now.

c63087a563 Remove ATK
To build a better world sometimes means having to tear the old one down.
        -- Alexander Pierce, "Captain America: The Winter Soldier"

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:

 - it maps to a very specific implementation, AT-SPI, which is Linux and
   Unix specific
 - it requires implementing the same functionality in three different
   layers of the stack: AT-SPI, ATK, and GTK
 - only GTK uses it; every other Linux and Unix toolkit and application
   talks to AT-SPI directly, including assistive technologies

Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:

 - add an "accessible" interface, implemented by GTK objects directly,
   which describe the accessible role and state changes for every UI
   element
 - add an "assistive technology context" to proxy a native accessibility
   API, and assign it to every widget
 - implement the AT context depending on the platform

6e52ef96a4 Move orientable style classes into GtkWidget
It feels slightly wrong to have GtkOrientable operate on widgets, but at
least what happens when an orientable widget changes orientation should
be part of GtkWidget.

This will allow to add more state changes without accessing widget state
from the outside of gtkwidget.c.

b93631164f Remove lots of focus vfuncs
In many cases, the default widget vfuncs work just fine,
combined with setting focusable.

632524f679 Reinstate expected focus behavior
After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.

This commit does that for all widgets.

4c150d8eb5 The big versioning cleanup
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.

43c212ac28 build: Enable -Wswitch-enum and -Wswitch-default
This patch makes that work using 1 of 2 options:

1. Add all missing enums to the switch statement
  or
2. Cast the switch argument to a uint to avoid having to do that (mostly
   for GdkEventType).

I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.

The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.

36ab70ddf5 widget: Add baseline and out_clip parameters to size-allocate
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.

This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.

f135b2527f center box: complete the baseline support
When there is no externally allocated baseline, we should
do the same thing that GtkBox does, and determine one from
the children that want baseline alignment.

This commit adds a GtkCenterBox::baseline-position property
with setters and getters.

066c1983ba actionbar: Add explicit center widget
The center widget in GtkBox was only introduced to use it in
GtkActionBar. However, the implementation there is much more complex
than it needs to be, so move the center widget into GtkActionBar instead
and later remove it from GtkBox.
