SfxPoolItems are held in SfxItemSets, which in turn store them in a
SfxItemPool. Some items are "pooled" that is, if you put them in a
SfxItemSet, it looks for the item in the SfxItemPool and if it is found
there, it just uses a reference to that one instead of keeping its own
copy. A weird form of refcounting in a way. An operator== returning
always false is thus claiming "never try to pool me". Why? Dunno, but
there might be reasons. ;)
Best Regards,
Bjoern
