* This virtual method allows to get a textual representation of the value

*
* Because the unit of measure of the value in the SfxItemPool is only
* queryable via @see SfxItemPool::GetMetric(sal_uInt16) const (and not
* via the SfxPoolItem instance or subclass, the own unit of measure is
* passed to 'eCoreMetric'.

* The corresponding unit of measure is passed as 'ePresentationMetric'.
*
*
* @return SfxItemPresentation SFX_ITEM_PRESENTATION_NAMELESS
* A textual representation (if applicable
* with a unit of measure) could be created,
* but it doesn't contain any semantic meaning
*
* SFX_ITEM_PRESENTATION_COMPLETE
* A complete textual representation could be
* created with semantic meaning (if applicable
* with unit of measure)
*
* Example:
*
* pSvxFontItem->GetPresentation( SFX_PRESENTATION_NAMELESS, ... )
* "12pt" with return SFX_ITEM_PRESENTATION_NAMELESS
*
* pSvxColorItem->GetPresentation( SFX_PRESENTATION_COMPLETE, ... )
* "red" with return SFX_ITEM_PRESENTATION_NAMELESS
* Because the SvxColorItem does not know which color it represents
* it cannot provide a name, which is communicated by the return value
*
* pSvxBorderItem->GetPresentation( SFX_PRESENTATION_COMPLETE, ... )
* "1cm top border, 2cm left border, 0.2cm bottom border, ..."
