11HISTORIQUE DES MODIFICATIONS :
12--------------------------------
1305-01-98 : CAL ; Creation.
1421-01-98 : FMN ; Ajout call_togl_end_animation().
1517-03-98 : FMN ; Ajout mode animation
1608-07-98 : FMN ; Changement du nom de la primitive call_togl_erase_immediat_mode()
17-> call_togl_erase_animation_mode.
1824-08-98 : BGN ; Correction de diag de compilation sur NT :
19Suppression de l'include OpenGl_animation.h qui
20provoque des doubles declarations.
