DESCRIPTION
     glXQueryVersion returns the major and minor version numbers of the	GLX
     extension implemented by the server associated with connection dpy.
     Implementations with the same major version number	are upward compatible,
     meaning that the implementation with the higher minor number is a
     superset of the version with the lower minor number.

     major and minor do	not return values if they are specified	as NULL.

     glXQueryVersion returns False if it fails,	True otherwise.	 major and
     minor are not updated when	False is returned.


NOTES
     If	the GLX	version	is 1.1 or 1.0, then the	GL version must	be 1.0.
