This assignment was shadowed by the giant switch above. Since the
switch has a comment or two explaining the logic inside of it,
keep that instead of the assignment.
Since the invoker for navigate_focus has an extra parameter, annotations
from the invoker aren't applied on the vfunc itself. Fix that by annotating
the vfunc separately.
This allows us to do directional keyboard navigation when there's no
actor inside the horizontal or vertical strip extending from the
origin actor but there are other actors to the sides of that strip
that could still be used as targets even if that means the focus would
move diagonally.

For arrow keys navigation, when moving from a widget which isn't a
descendant of the widget we are going to, it's unexpected that focus
moves to the target's first descendant instead of the closest to the
source widget.
This requires us to use absolute coordinates to compare widgets since
we no longer have the guarantee that the widgets we are comparing are
siblings.

When porting from st_container_get_children_list to this code, I accidentally
broke StTable by a copy/paste error. This broke notifications that updated,
leaving them with what they think were 0 columns and 0 rows.

The very similar clutter_actor_allocate_align_fill is close enough
that this is just needless duplication. Additionally, allocate_fill
already inverts the align if the text direction is RTL, so we don't
need to do that here.

Now that StWidget is a group of sorts, it needs to account for its children
in its paint volume. Unfortunately, this causes havoc for StBoxLayout, so it
needs fixing - it's unknown why it worked when chaining up to near-identical
code in StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
The get_focus_chain() implementation in StWidget just returns all
children, it should filter for visible children instead. This
breaks keyboard navigation in various places since commit 72dad591
removed the correct implementation in StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670904
Now that ClutterActor has a ClutterContainer implementation, we
can start removing StContainer. To help make this a bit more
understandable, instead of converting everything at once, make
StContainer a compatible API wrapper around the ClutterActor
implementation, and then we'll remove those wrappers in later
commits.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Since an StWidget now has children, it needs to allocate those children
properly. Defer to the currently installed layout manager, like Clutter
does.
Now that we have something that allocates children in St, to prevent
double allocations, we use clutter_actor_set_allocation rather than
chaining up to StWidget::allocate.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Now that StWidget is concrete and instantiable, we need to do something
other than return an adjusted 0 for width and height. Just chain up
to ClutterActor's default implementation, which uses the layout manager.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Since we want to paint children by default in StWidget, we need to
provide a way for custom subclasses to paint their CSS backgrounds
without painting children... introducing st_widget_paint_background.
Additionally, remove any custom paint/pick handlers added by subclasses
of StWidget that just painted their children. This will cause double
painting if left alone.
This also removes the hacky things that some subclasses of StBin did
to prevent their one child to be painted by StBin.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Clutter now provides two new properties on ClutterActor - first-child
and last-child, so we have notifiers on when they change. Unfortunately,
it still doesn't help us too much - we need to keep track of the previous
values of the properties so we can remove their pseudoclasses.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
We can't get rid of the implementations in StContainer just yet,
as StContainer still keeps its own child list. But this should
lower the amount of code that has to be moved around when we
remove StContainer.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
clutter_container_foreach is deprecated, so let's replace that
with some ClutterActorIter usage. Additionally, remove the checks
for ClutterContainer, as all ClutterActors are now ClutterContainers.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
The handle was a child of the trough, but it was allocated and painted
like it was a child of the bar. This will wreak havoc when we port over
to the new Clutter API, so let's just make it a child of the bar.
https://bugzilla.gnome.org/show_bug.cgi?id=670034
Clutter, since version 1.8, does The Right Thing™ inside the default
implementation of ClutterActor::map and ClutterActor::unmap, even for
non-container actors: it will iterate over the list of children and
map, or unmap, each one of them, respectively.
This means that the requirement to override map and unmap for composite
actors to map and unmap the internal children has been dropped.

Since our implementation of background-size is now CSS-compliant, we
do not need this subtexture hack that clips a "leak". The comment here
is also incorrect.
https://bugzilla.gnome.org/show_bug.cgi?id=633462
It seems that accidentally, two variables were swapped in one code path
of the background-size implementation, causing interesting but wrong
images for some elements.
