/**
 * GtkSizeGroup provides a mechanism for grouping a number of widgets
 * together so they all request the same amount of space. This is
 * typically useful when you want a column of widgets to have the same
 * size, but you can't use a GtkGrid widget.
 *
 * In detail, the size requested for each widget in a GtkSizeGroup is
 * the maximum of the sizes that would have been requested for each
 * widget in the size group if they were not in the size group. The mode
 * of the size group (see gtk_size_group_set_mode()) determines whether
 * this applies to the horizontal size, the vertical size, or both sizes.
 *
 * Note that size groups only affect the amount of space requested, not
 * the size that the widgets finally receive. If you want the widgets in
 * a GtkSizeGroup to actually be the same size, you need to pack them in
 * such a way that they get the size they request and not more. For
 * example, if you are packing your widgets into a table, you would not
 * include the GTK_FILL flag.
 *
 * GtkSizeGroup objects are referenced by each widget in the size group,
 * so once you have added all widgets to a GtkSizeGroup, you can drop
 * the initial reference to the size group with g_object_unref(). If the
 * widgets in the size group are subsequently destroyed, then they will
 * be removed from the size group and drop their references on the size
 * group; when all widgets have been removed, the size group will be
 * freed.
 *
 * Widgets can be part of multiple size groups; GTK+ will compute the
 * horizontal size of a widget from the horizontal requisition of all
 * widgets that can be reached from the widget by a chain of size groups
 * of type GTK_SIZE_GROUP_HORIZONTAL or GTK_SIZE_GROUP_BOTH, and the
 * vertical size from the vertical requisition of all widgets that can be
 * reached from the widget by a chain of size groups of type
 * GTK_SIZE_GROUP_VERTICAL or GTK_SIZE_GROUP_BOTH.
 *
 * Note that only non-contextual sizes of every widget are ever consulted
 * by size groups (since size groups have no knowledge of what size a widget
 * will be allocated in one dimension, it cannot derive how much height
 * a widget will receive for a given width). When grouping widgets that
 * trade height for width in mode GTK_SIZE_GROUP_VERTICAL or GTK_SIZE_GROUP_BOTH:
 * the height for the minimum width will be the requested height for all
 * widgets in the group. The same is of course true when horizontally grouping
 * width for height widgets.
 *
 * Widgets that trade height-for-width should set a reasonably large minimum width
 * by way of "width-chars" for instance. Widgets with static sizes as well
 * as widgets that grow (such as ellipsizing text) need no such considerations.
 *
 * GtkSizeGroup as GtkBuildable
 *
 * Size groups can be specified in a UI definition by placing an
 * <object> element with class="GtkSizeGroup"
 * somewhere in the UI definition. The widgets that belong to the
 * size group are specified by a <widgets> element that may
 * contain multiple <widget> elements, one for each member
 * of the size group. The name attribute gives the id of the widget.
 *
 * $(DDOC_COMMENT example)
