\class CEngine
\brief The graphics engine
This is the main class for graphics engine. It is responsible for drawing the 3D scene,
setting various render states, and facilitating the drawing of 2D interface.
It uses a lower-level CDevice object which is implementation-independent core engine.
\section Objecs Engine objects
The 3D scene is composed of objects which are basically collections of triangles forming
a surface or simply independent triangles in space. Objects are stored in the engine
as a tree structure which is composed of 5 tiers (EngineObjLevel1, EngineObjLevel2 and so on).
Each tier stores some data about object triangle, like textures or materials used.
Additional information on objects stored are in EngineObject structure.
Each object is uniquely identified by its rank.
