 *
 * Alignment only matters if the widget receives a “too large” allocation,
 * for example if you packed the widget with the [property@Gtk.Widget:hexpand]
 * property inside a `GtkBox`, then the widget might get extra space.
 * If you have for example a 16x16 icon inside a 32x32 space, the icon
 * could be scaled and stretched, it could be centered, or it could be
 * positioned to one side of the space.
 *
 * Note that in horizontal context %GTK_ALIGN_START and %GTK_ALIGN_END
 * are interpreted relative to text direction.
 *
 * %GTK_ALIGN_BASELINE support is optional for containers and widgets, and
 * it is only supported for vertical alignment.  When it's not supported by
 * a child or a container it is treated as %GTK_ALIGN_FILL.
