24//! Creates an arbitrary located instance of another Interactive Object,
25//! which serves as a reference.
26//! This allows you to use the Connected Interactive
27//! Object without having to recalculate presentation,
28//! selection or graphic structure. These are deduced
29//! from your reference object.
30//! The relation between the connected interactive object
31//! and its source is generally one of geometric transformation.
32//! AIS_ConnectedInteractive class supports selection mode 0 for any InteractiveObject and
33//! all standard modes if its reference based on AIS_Shape.
34//! Descendants may redefine ComputeSelection() though.
35//! Also ConnectedInteractive will handle HLR if its reference based on AIS_Shape.
