Icon theme change signals aren't noticed immediately, they're usually
noticed when trying to load an icon. Since icon theme changes cause a
style change, and most icon widgets try to re-load their texture during
a style change, this means that we get a stack like this:
st_texture_cache_load_icon
gtk_icon_theme_lookup_icon
gtk_icon_theme_changed
st_widget_style_changed
st_texture_cache_load_icon
Rather than making every place that uses StTextureCache re-entrant,
punt the notifying of icon theme changes to an idle handler instead.

Currently compilation fails with -Werror, as we don't handle the
(newly introduced) smooth scroll events in switch statements; add
some basic support, which should make the compiler happy.

More than one outstanding request to the same URI should now be
deduplicated, and the framework is there if we want to cache async loaded
URIs as well
https://bugzilla.gnome.org/show_bug.cgi?id=672273
In the case that we don't have an icon corresponding to the gicon, it's
more than likely that the code calling load_gicon will know more about
what it wants as a fallback than the texture-cache itself. In fact -
we had a whole lot of dead code that would try to fall back, but never
did because we always returned a valid actor.
This was causing certain applications with invalid icons to not get the
fallback icon because an icon couldn't be found. Fix up the one place
where we don't have an explicit fallback icon codepath, and then stop
doing what we were doing.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=663901
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.
