/**
* SECTION:clutter-box
* @short_description: Base class for layout containers
*
* #ClutterBox is a base class for containers which impose a specific layout
* on their children, unlike #ClutterGroup which is a free-form container.
*
* Layout containers are expected to move and size their children depending
* on a layout contract they establish per-class. For instance, a #ClutterHBox
* (a subclass of #ClutterBox) lays out its children along an imaginary
* horizontal line.
*
* All #ClutterBox<!-- -->es have a margin, which is decomposed in four
* components (top, right, bottom left) and a background color. Each child
* of a #ClutterBox has a packing type and a padding, decomposed like the
* margin. Actors can be packed using clutter_box_pack() and providing
* the packing type and the padding, or using clutter_box_pack_defaults()
* and setting a default padding with clutter_box_set_default_padding().
* A #ClutterBox implements the #ClutterContainer interface: calling
* clutter_container_add_actor() on a #ClutterBox will automatically invoke
* clutter_box_pack_defaults().
*
* Each child of a #ClutterBox has its packing information wrapped into the
* #ClutterBoxChild structure, which can be retrieved either using the
* clutter_box_query_child() or the clutter_box_query_nth_child() function.
*
* Subclasses of #ClutterBox must implement the ClutterBox::pack_child and
* ClutterBox::unpack_child virtual functions; these functions will be called
* when adding a child and when removing one, respectively.
*
* #ClutterBox is available since Clutter 0.4

* SECTION:clutter-layout
* @short_description: An interface for implementing layouts
*
* #ClutterLayout is an interface that #ClutterActor<!-- -->s might
* implement to provide complex or extended layouts. The default
* size allocation of a #ClutterActor inside a #ClutterGroup is to
* make the group size allocation grow enough to contain the actor.
* A #ClutterActor implementing the #ClutterLayout interface will
* be queried for its size when it is added to a #ClutterGroup subclass
* that honours the #ClutterLayout interface; the resulting size
* allocation will depend on the #ClutterLayoutFlags that the actor
* supports.
*
* There are various types of layout available for actors implementing
* the #ClutterLayout interface: %CLUTTER_LAYOUT_WIDTH_FOR_HEIGHT will
* ask the actor for its width given the height allocated by the
* container; %CLUTTER_LAYOUT_HEIGHT_FOR_WIDTH will ask the actor for
* its height given the width allocated by the container. These two
* layout types are especially useful for labels and unidirectional
* container types, like vertical and horizontal boxes.
*
* Another layout available is %CLUTTER_LAYOUT_NATURAL, which will
* query the actor for its natural (default) width and height; the
* container actor will then try to allocate as much as it can,
* and might resort to scaling the actor to fit the allocation. This
* layout type is suited for #ClutterTexture<!-- -->s and shapes.
*
* Finally, the %CLUTTER_LAYOUT_TUNABLE is an iterative layout. An actor
* will be queried multiple times until it's satisfied with the size
* given.
*
* A #ClutterContainer implementation that honours the #ClutterLayout
* interface should check whether an actor is implementing this interface
* when adding it, by using the %CLUTTER_IS_LAYOUT type check macro. If the
* actor does implement the interface, the #ClutterContainer should get
* the supported layouts using clutter_layout_get_layout_flags() and
* verify which layout is compatible with the group's own layout; for
* instance, vertical containers should check for actors implementing the
* %CLUTTER_LAYOUT_WIDTH_FOR_HEIGHT layout management, while horizontal
* containers should check for actors implementing the
* %CLUTTER_LAYOUT_HEIGHT_FOR_WIDTH layout management. If the actor
* satisfies the layout requirements, the container actor should query
* the actor for a geometry request using the appropriate function and
* allocate space for the newly added actor accordingly.
