/*  [Beschreibung]

    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.
