Subject: Ajout du bit COMPOSE_ALPHA_BIT Ajout des structures ZnToAreaStruct et
 ZnPickStruct pour simplifier l'interface des m�thodes ToArea et Pick et
 accomoder les nouvelles fonctionalit�s des commandes de find/addtag.
 Modification des prototypes de ToArea et Pick. Suppression de la variable de
 classe has_fields.
