IItem interface gives access to individual
items in the 3D scene rendered
during the model display. IItem is a common
base for Sections (ISection) and 3D Label items.
IItem is used mostly to query from all other interface implemented by the
element of the scene.
Query ITypeBasic_KC from this interface to
obtain type of the item
