//! A framework to supply the Graphic3d structure of the object to be presented.
//! On the first display request, this structure is created by calling the appropriate algorithm and retaining this framework for further display.
//! This abstract framework is inherited in Application Interactive Services (AIS), notably by AIS_InteractiveObject.
//! Consequently, 3D presentation should be handled by the relevant daughter classes and their member functions in AIS.
//! This is particularly true in the creation of new interactive objects.
//!
//! Key interface methods to be implemented by every Selectable Object:
//! - AcceptDisplayMode() accepting display modes implemented by this object;
//! - Compute() computing presentation for the given display mode index.
//!
//! Warning! Methods managing standard attributes (SetColor(), SetWidth(), SetMaterial()) have different meaning for objects of different type (or no meaning at all).
//! Sub-classes might override these methods to modify Prs3d_Drawer or class properties providing a convenient short-cut depending on application needs.
//! For more sophisticated configuring, Prs3d_Drawer should be modified directly, while short-cuts might be left unimplemented.
