+ * The area tree needs to be simple to render and follow the spec
+ * closely.
+ * This area tree has the concept of page sequences.
+ * Where ever possible information is discarded or optimised to
+ * keep memory use low. The data is also organised to make it
+ * possible for renderers to minimise their output.
+ * A page can be saved if not fully resolved and once rendered
+ * a page contains only size and id reference information.
+ * The area tree pages are organised in a model that depends on the
