Bibliothèque sequa::3d (espace de noms sequa::three_d), sans dépendance à un moteur : interface I3DEngineAdapter, tampons et négociation des capacités, synchronisation de la scène par deltas versionnés tout ou rien (SceneState, snapshot), demandes d'image et mesures communes. NullEngineAdapter (SIMULÉ) pour les tests. Types provisoires en attendant le format du schéma.
