These functions, while added for use by the GTK inspector, are generally
useful to applications that need to resolve what action groups are
available to a particular GtkWidget.

Without this, the focus will not be inside the top_stack when
we switch to the statistics page and it shows the excuse. This
in turn will make the next page not take focus as expected when
switching away from the statistics page again.
Add notebook-like focus handling: Keep track of the last focused
descendent of each page, and focus it again when switching back
to the page. If there is no last focused child, we move the focus
into the page as if the user had hit Tab.
When using a completion with some custom cells in the cell layout,
if would often size wrong when first presented on screen.
The entry completion is the only place in the entire gtk code base
that calls gtk_tree_view_column_cell_get_size outside of gtktreeview
itself. It calls into the function before the tree view has done some
important validation on its cell state, the net result of which is
only the first element in the gtkcellareabox the entry completion uses
well actually have its size respected.
We now call gtk_widget_get_preferred_size on the tree view before
calling into the individual cell size routines, to guarantee that the
tree view has run its validate_rows routine and cell state is valid.

Use the new scrollable API for getting non-scrollable borders
and draw over/undershoot at the right place. In practice, this
means that they now appear below treeview headers.
Add a vfunc to return a non-scrollable border around scrollables.
This would be nicer as a property, but we can't add properties
to an interface without breaking 3rd party implementations, so
make this an optional vfunc, and handle it not being set.
The new region selector tracks more than just one soimple selector, so
it requires some more advanced specificity tracking.
Technically, this is still not correct, because it will report the same
specificity for
tab:sorted
and
tab:sorted:sorted
(and the second selector will be printed as the first) but this is
regions, so meh.
This is just a way to handle regions more conveniently. What this does
is to change the descendant matcher into a maybe-descendant matcher
whenever the current object we're parsing might be a region. Because "*"
might also refer to a region and not just a new element.
See testsuite/reftests/css-match-region-matches-star.ui for a testcase.
When parsing a selector like
tab:active
We used to create 2 selector objects, one for the region, and one for
the pseudoclass. Now, for convenience, we special-case region
pseudoclass parsing so that the active flag is added to the region
selector.
A side effect is that ":nth-child(1)" no longer works for regions.
Hopefully people didn't use this but used the saner ":first-child"
instead.
We used to switch to the objects tab when an object is
picked, but now may have two places with picker buttons:
the objects tab and the interactive tab.
So, just don't do that anymore.
Currently we only take into account the window GActionGroup for
activating the accels.
However, the application could have some custom GActionGroup in the
chain of focused widgets that could want to activate some action if
some accel is activated while that widget is focused.
To allow applications to set accels on widgets that use custom
GActionGroups, simply use the muxer of the focused widget, which
already contains the actions of the parents.
