The intention of the expand widget flags was to in fact propagate
legacy expand child properties as well. Due to implementation errors,
this was only happening in some cases, but not in others. To avoid
breaking old code assuming traditional expand flag behavior, this
commit removes all attempts to propagate GtkBox::expand.
This was discussed in
https://bugzilla.gnome.org/show_bug.cgi?id=698656 and

This patch was written by Tristan Van Berkom.
Report a baseline based height and baseline whenever there
are children with ALIGN_BASELINE.
Assign baseline to childen in size_allocate. Either the one inherited
from the parent if set, or otherwise calculate one based on any
ALIGN_BASELINE children.
If you want to get rounded corners on an hbox, instead of
:first-child {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
you now need to write:
:first-child, :last-child:dir(rtl) {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child, :first-child:dir(rtl) {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
Add an internal API that allows GtkStyleContext to create a widget path
for the widget and with that bypassing gtk_widget_get_path() and that
function caching the path.
Use foreach() instead of forall() to find the child's siblings
because internal children of subclasses have no sibling relation
to the box' children. Also deal with the subclass failing to
implement get_path_for_child(). This caused an infinite widget
path invalidation loop of sorts with GimpMessageBox, which is a
vertical box with a decorative icon to the left.
At the same time, drop the AtkText implementation.
Also, reintroduce a GtkBoxAccessible, since the previous
way of setting the role in get_accessible was affecting
GtkBox subclasses negatively.
Adjust expected test output to match.
When we build the sibling path for the order, we do not skip hidden
children (since, quoting the comment, "we cannot reliably detect changes
in widget visibility"). So we need to invalidate the order when hidden
children are reordered and removed.

Stop documenting the base class as just a base class for the
H and V specializations, copying the useful descriptions from
those H/V classes to the base class. Do not advise the use of
the H/V classes or refer to them unnecessarily.
