	Der im Normalfall verwendete Konstruktor der Klasse SfxItemPool. Es
	wird eine SfxItemPool-Instanz initialisiert, die Items im b"undigen
	Which-Bereich von 'nStartWhich' bis 'nEndWhich' verwalten kann.

	F"ur jede dieser Which-Ids mu\s ein statischer Default im Array 'pDefaults'
	vorhanden sein, die dort beginnend mit einem <SfxPoolItem> mit der
	Which-Id 'nStartWhich' nach Which-Ids sortiert aufeinanderfolgend
	eingetragen sein m"ussen.

	'pItemInfos' ist ein identisch angeordnetes Array von USHORTs, die
	Slot-Ids darstellen und Flags. Die Slot-Ids k"onnen 0 sein, wenn die
	betreffenden Items ausschlie\slich in der Core verwendet werden.
	"Uber die Flags kann z.B. bestimmt werden, ob Value-Sharing
	(SFX_ITEM_POOLABLE) stattfinden soll.

	[Anmerkung]

	Wenn der Pool <SfxSetItem>s enthalten soll, k"onnen im Konstruktor noch
	keine static-Defaults angegeben werden. Dies mu\s dann nachtr"aglich
	mit <SfxItemPool::SetDefaults(SfxItemPool**)> geschehen.
