//! The Interactive Context allows you to manage
//! graphic behavior and selection of Interactive Objects
//! in one or more viewers. Class methods make this
//! highly transparent.
//! It is essential to remember that an Interactive Object
//! which is already known by the Interactive Context
//! must be modified using Context methods. You can
//! only directly call the methods available for an
//! Interactive Object if it has not been loaded into an
//! Interactive Context.
//! You must distinguish two states in the Interactive Context:
//! -   No Open Local Context, also known as the Neutral Point.
//! -   One or several open local contexts, each
//! representing a temporary state of selection and presentation.
//! Some methods can only be used in open Local
//! Context; others in closed Local Context; others do
//! not have the same behavior in one state as in the other.
//! The possiblities of use for local contexts are
//! numerous depending on the type of operation that
//! you want to perform, for example:
//! -   working on all visualized interactive objects,
//! -   working on only a few objects,
//! -   working on a single object.
//! 1. When you want ot work on one type of entity, you
//! may open a local context with the option
//! UseDisplayedObjects set to false. DisplayedObjects
//! allows you to recover the visualized Interactive
//! Objects which have a given Type and
//! Signature   from Neutral Point.
//! 2. You must keep in mind the fact that when you open
//! a Local Context with default options:
//! -   The Interactive Objects visualized at Neutral Point
//! are activated with their default selection mode. You
//! must deactivate those which you do not want ot use.
//! -   The Shape type Interactive Objects are
//! automatically decomposed into sub-shapes when
//! standard activation modes are launched.
//! -   The "temporary" Interactive Objects present in the
//! Local Contexts are not automatically taken into
//! account. You have to load them manually if you
//! want to use them.
//! -   The stages could be the following:
//! -   Open a Local Context with the right options;
//! -   Load/Visualize the required complementary
//! objects with the desired activation modes.
//! -   Activate Standard modes if necessary
//! - Create its filters and add them to the Local Context
//! -   Detect/Select/recover the desired entities
//! -   Close the Local Context with the adequate index.
//! -   It is useful to create an interactive editor, to which
//! you pass the Interactive Context. This will take care
//! of setting up the different contexts of
//! selection/presentation according to the operation
//! which you want to perform.

//! Selection of parts of the objects can also be done without opening a local context.
//! Interactive context itself supports decomposed object selection with selection filters
//! support. Note that each selectable object must specify the selection mode that is
//! responsible for selection of object as a whole (global selection mode). By default, global
//! selection mode is equal to 0, but it might be redefined if needed. Sub-part selection
//! of the objects without using local context provides a possibility to activate part
//! selection modes along with global selection mode.
