* Fonction
* ~~~~~~~~
* Gestion des extensions sous OpenGL
*
*
* Attention:
* ~~~~~~~~~~~
* Ce package a ete teste sur SGI, OSF, SUN, HP et WNT.
*
* Remarques:
* ~~~~~~~~~~~
* Le InitExtensionGLX permet d'initialiser le display. Ceci est necessaire
* pour travailler sur les extensions de GLX. On ne peut appeler QueryExtensionGLX
* si on n'a pas fait cette manip.
* Par contre QueryExtension gere les extensions a GL, on n'a pas besoin du
* Display.
*
* Pour l'instant on ne gere pas les extensions a GLU et a WGL.
*
* Historique des modifications
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 14-10-97: FMN ; Creation
* 23-10-97: FMN ; Ajout gestion glx
* 19-11-97: FMN ; Ajout GetCurrentDisplay
* 04-12-97: FMN ; Ajout supportsOneDotOne
* 19-06-98: FMN ; Portage Optimizer (C++)
