[Beschreibung]
Linker/Rechter Rand sowie Erstzeileneinzug

SvxLRSpaceItem bietet zwei Schnittstellen zur Befragung des linken
Randes und des Erstzeileneinzuges an. Die Get-Methoden liefern
die Member zurueck, wie sie das Layout bisher auch erwartete:
Der linke Rand verschiebt sich beim negativem Erstzeileneinzug
nach links. Die SetTxt/GetTxt-Methoden setzen voraus, dass der
linke Rand der 0-Punkt des Erstzeileneinzugs darstellt:
