* \par Function Description
* This function traverses the hierarchy tree of pages and returns a
* flat list of pages that are below \a p_current. There are two \a
* flags that can be used to control the way that the return value is
* constructed: <B>HIERARCHY_NODUPS</B> returns a list without
* duplicate pages, and <B>HIERARCHY_POSTORDER</B> traverses the
* hierarchy tree and returns a postorder list instead of preorder.
*
* \param toplevel The TOPLEVEL structure.
* \param p_current The PAGE to traverse hierarchy for.
* \param flags Flags controlling form of return value.
* \return A GList of PAGE pointers.
*
* \warning
* Caller must destroy returned GList with g_list_free().
