	La classe GhostElement herite de la classe CustomElement. Un GhostElement
	est destine a remplacer visuellement un CustomElement dont la definition
	n'a pu etre trouvee. Ainsi, au lieu de ne pas charger un element, et donc
	de perdre potentiellement :
	  * sa position, son orientation, ses textes,
	  * les conducteurs qui y sont lies,
	on peut lui substituer un GhostElement. Celui-ci extrapolera depuis le
	schema la position des bornes et des champs de texte.
	Visuellement, il sera represente par un rectangle.
