xx-xx-xx : xxx ; Creation.
11-03-96 : FMN ; Correction warning compilation
01-04-96 : CAL ; Integration MINSK portage WNT
08-07-96 : BGN ; (PRO4768) suppression du cas particulier TEL_PM_DOT.
21-10-96 : FMN ; Suppression LMC_COLOR fait dans OpenGl_execstruct.c
19-10-96 : CAL ; Restauration du cas particulier TEL_PM_DOT mais
avec la correction sur la mise a jour du pointSize.
