<title>Stop using GtkBox's pack-type child property</title>
<para>
In order to improve performance and simplify the widget, GtkBox lost its
'pack-type' child property. In GTK+4, every GtkBox instance has a simple
list of child widgets that it allocates from start to end.
The old behavior of pack-type=END can be emulated by simply making the
box child in the center hexpand and right-align the ones at the end.
