/**
* SECTION:st-group
* @see_also:#ClutterGroup
* @short_description: A fixed layout container
*
* A #StGroup is an Actor which contains multiple child actors positioned
* relative to the #StGroup position. Other operations such as scaling,
* rotating and clipping of the group will apply to the child actors.
*
* A #StGroup's size is defined by the size and position of its children;
* it will be the smallest non-negative size that covers the right and bottom
* edges of all of its children.
*
* Setting the size on a Group using #ClutterActor methods like
* clutter_actor_set_size() will override the natural size of the Group,
* however this will not affect the size of the children and they may still
* be painted outside of the allocation of the group. One way to constrain
* the visible area of a #StGroup to a specified allocation is to
* explicitly set the size of the #StGroup and then use the
* #ClutterActor:clip-to-allocation property.
