HISTORIQUE DES MODIFICATIONS :
--------------------------------
05-01-98 : CAL ; Creation.
21-01-98 : FMN ; Ajout call_togl_end_animation().
17-03-98 : FMN ; Ajout mode animation
08-07-98 : FMN ; Changement du nom de la primitive call_togl_erase_immediat_mode()
-> call_togl_erase_animation_mode.
24-08-98 : BGN ; Correction de diag de compilation sur NT :
Suppression de l'include OpenGl_animation.h qui
provoque des doubles declarations.
