f003a4c6cc gtkwindow: Simplify GTK grab notification
The _gtk_widget_grab_notify() function just (maybe) did a) reset
controllers and b) hide toplevels. The second part was a testing
remnant introduced in commit 024d832d94, not part of the original
fix.

Do the former more concisely, called from the place where we figure
out whether a widget's ability to receive events changed due to
GTK grabs. It's across those changes that we are interested in
resetting the controllers.

With the gestures being reset both ways, GtkWindowHandle (and
probably other) gestures are now able to reset after a GTK grab
takes input away (e.g. GtkMenuButton). This could be seen as
a sudden jump the next time they'd be dragged with the mouse,
as the gesture would "resume" the previous interaction.

a455db01a0 a11y: Actually set accessible roles
With most context realization happening inside
GtkAtspiContext in response to D-Bus calls, the
code in gtk_widget_realize_at_context that sets
the role is not executed for most accessibles,
causing them to be stuck with the 'filler' role
that makes orca ignore them.

To fix this, split gtk_widget_realize_at_context
into the actual context realization (getting on
the bus) and the setting of widget-specific
properties, and do the latter part when the
widget is rooted.

This makes accerciser report proper roles for
entries and buttons. Orca still has an issue
with getting the hierarchy populated.

9e8187bdc4 a11y: Track window states more closely
Orca ignores events unless the object is inside an object
with role window and states ACTIVE and SHOWING. To arrange
for this, introduce a new ACTIVE platform state, and set it
for windows when they are active.

This gets orca to be a lot more talkative.

5556907194 inspector: Fix surface transform regression
Ever since we added surface-to-widget transforms,
the autofading of the fps overlay did not work anymore,
since it was given the transient transform node, most
of the time.

Fix this by passing both the root of the node tree and
the node for the toplevel widget to prepare_render, and
hande the widget node to the overlays. Update the
affected overlays that need to have their positioning
adjusted.

28f5d26719 windowhandle: Don't drag on capture phase
This was needed to work around widgets claiming event sequences on press,

The most visible offender was GtkButton, but since the last commit it
doesn't claim the sequence anymore and we can remove the hack.

8a599b2582 gtk: Allocate everything from GtkNativeClass::layout
This changes allocation of the widget trees to happen as a side effect
to the GdkSurface::layout signal, which first passes the GtkNative
instance where it is then forwarded to the implementations of the
GtkNative interface.

The implementations of GtkNative are the ones doing the actual
gtk_widget_allocate(), and they do so in their GtkNativeClass::layout
function.

b3e03fa6f0 Add wrappers for setting the WidgetClass.activate_signal field
Setting a field on a class structure is not always an easy task from
languages other than C. While bindings can provide access to the class
pointer, twiddling the fields in the class structure can be awkward.
Additionally, signal ids are not always readily available.

We can paper over the direct access to the class structure, as well as
the "signal name to id" mapping with a simple couple of setter
functions.

9052f6dafe a11y: Rework ownership and lifetime of GtkATContext
Now that GtkATContext is explicitly realized and unrealized, we should
always create an instance at widget initialization time, and drop it
during the widget finalization. This should make it easier to set up the
initial accessible state of a widget during the instance initialization,
as well as reduce the chances of accidental creation of GtkATContext
instances during the destruction sequence.

428ec29598 a11y: Unrealize ATContext on dispose()
By unrealizing the context we avoid additional work during the dispose

of the one we store inside GtkWidgetPrivate.

We drop the ATContext instance inside GtkWidget during finalization, to
mop up eventual vivifications there.

27c4c19333 Don't hide widgets in dispose()
This is leftover code from when widgets were hidden
by default, and was setting them back to their initial
state.

This is getting in the way now, as hiding the widget
updates the HIDDEN accessible state, which ends up
re-creating the at context that we've already disposed
of, leading to memory leaks.

1bdc8b9061 a11y: Proxy GtkWidget:accessible-role
The accessible-role property in GtkWidget has three possible targets:

 - the :accessible-role of a GtkATContext, if realized
 - the accessible_role field of GtkWidgetPrivate
 - the accessible_role field of GtkWidgetClassPrivate

When we set the accessible role of a widget using the GObject property
mechanism, we want to either set the GtkWidgetPrivate.accessible_role
field, if there's no ATContext *or* if the ATContext is not realized.
Conversely, when we get the accessible-role property we want to have a
series of fallbacks in place:

 - if GtkAccessible.get_at_context() returns an ATContext, and that
   ATContext is realized, return the :accessible-role of the context
 - if GtkWidgetPrivate.accessible_role is not WIDGET, return the
   stored accessible role
 - return GtkWidgetClassPrivate.accessible_role

This should help catch the case of getting the accessible role of
widgets that override GtkAccessible.get_at_context(), like
GtkModelButton.

9e4316bf96 a11y: Add an "accessibility" section to the builder XML tree
Accessible attributes are not GObject properties. This means that we
need a custom parser for setting attributes in our UI description files.

The new section is defined as a sub-tree with the `<accessibility>`
element at its root, and elements for each type of accessible
attributes, i.e. properties, relations, and states:

```xml
  <object class="..." id="...">
    <accessibility>
      <property name="label">The accessible label</property>
      <state name="pressed">false</state>
      <relation name="labelled-by">label1</relation>
    </accessibility>
  </object>
```

The name of the attribute is the enumeration value; the value is defined
by the WAI-ARIA specification.

ade9e4b82a accessible: Add gtk_accessible_get_platform_state
As a companion to go with the platform_change api,
add a gtk_accessible_get_platform_state() function
that can be used by backends to get the platform
state.

This is in preparation for making entries inherit
their focus states from the text widget within.

a2d220edfa widget: Notify a11y of focus changes
This is using the new 'platform changes' mechanism
to tell the a11y backends when focus changes.

35f70d5a99 Pass orientation property to accessible
We should set the accessible properties we have,
where they make sense. So set orientation, if the
widget is orientable.

658d910967 a11y: Ignore widgets during destruction
There's no point in creating a GtkATContext when a widget is getting
destroyed.

8c18480092 a11y: Add a display to GtkATContext
Since we need to check at run time what kind of AT context to use, we
need a hook into the whole GDK backend machinery. The display connection
seems to be the best choice, in this case, as it allows us to determine
whether we're running on an X11 or Wayland system, and thus whether we
should create a GtkAtSpiContext.

This requires some surgery to fix the GtkATContext creation function, in
order to include a GdkDisplay instance.

d2f0e3fa6b doc: Document some apis as widget implementor only
A better solution for this would be nice. For the
time being, just add a sentence to the docs.

12189bc10f buildable: Rename set_name() to set_buildable_id()
GtkBuildable's get_name()/set_name() methods may shadow
GtkWidget's methods. Avoid that by renaming the API to
get_buildable_id()/set_buildable_id(), which also reflects
the name of the XML attribute the API refers to.

d89f7fd046 Drop gtk_widget_new
An abstract type should not have a constructor.
If you want to be generic, just use g_object_new.

67c1600ac2 Document some API as widget-implementation only
Using gtk_widget_insert_before on a complex container
is a *bad* idea; it will mess up the containers bookkeeping
of its children and can easily lead to failure and crashes.

30ab8b3eca Fix picking
My previous change here was too hasty - this code is not
actually transforming points - it is just a convoluted
way to transform the z axis from child coordinates to
the parent.

e36b594867 Replace uses of graphene_matrix_transform_
Replace our uses of graphene_matrix_transform_point,
_point3d and _bounds by our own versions that handle
projective transforms correctly.

This fixes render node bounds being incorrect for widgets
involving projective transforms (e.g. testrevealer swing
transformations), and also fixes picking on such widgets.
