//! This class furnish services to defined and fill an
//! array of primitives compatible with the use of
//! the OPENGl glDrawArrays() or glDrawElements() functions.
//! NOTE that the main goal of this kind of primitive
//! is to avoid multiple copies of datas between
//! each layer of the software.
//! So the array datas exist only one time and the use
//! of SetXxxxxx() methods enable to change dynamically
//! the aspect of this primitive.
//!
//! Advantages are :
//! 1) Decrease strongly the loading time.
//! 2) Decrease strongly the display time using optimized Opengl
//! primitives.
//! 3) Enable to change dynamically the components of the primitive
//! (vertice,normal,color,texture coordinates).
//! 4) Add true triangle and quadrangle strips or fans capabilities.
