|*
|*	Beschreibung		Wenn sich die Groesse eines Frm's direkt unterhalb
|* 		eines Fussnotenbosses (Seite/Spalte) veraendert hat, so muss dieser
|*  	"Normalisiert" werden.
|* 		Es gibt dort immer einen Frame, der den "maximal moeglichen" Raum
|*		einnimmt (der Frame, der den Body.Text enhaelt) und keinen oder
|* 		mehrere Frames die den Platz einnehmen den sie halt brauchen
|* 		(Kopf-/Fussbereich, Fussnoten).
|*		Hat sich einer der Frames veraendert, so muss der Body-Text-Frame
|*		entsprechen wachsen oder schrumpfen; unabhaegig davon, dass er fix ist.
|* 		!! Ist es moeglich dies allgemeiner zu loesen, also nicht auf die
|* 		Seite beschraenkt und nicht auf einen Speziellen Frame, der den
|* 		maximalen Platz einnimmt (gesteuert ueber Attribut FrmSize)? Probleme:
|* 		Was ist wenn mehrere Frames nebeneinander stehen, die den maximalen
|* 		Platz einnehmen?
|*		Wie wird der Maximale Platz berechnet?
|* 		Wie klein duerfen diese Frames werden?
|*
|* 		Es wird auf jeden Fall nur so viel Platz genehmigt, dass ein
|* 		Minimalwert fuer die Hoehe des Bodys nicht unterschritten wird.
|*
|*	Parameter: nDiff ist der Betrag, um den Platz geschaffen werden muss
