DESCRIPTION
       X  rendering  calls made prior to glXWaitX are guaranteed to be executed
       before GL rendering calls made after glXWaitX.  Although the same result
       can  be  achieved using XSync, glXWaitX does not require a round trip to
       the server, and it is therefore more efficient in cases where client and
       server are on separate machines.

       glXWaitX is ignored if there is no current GLX context.

NOTES
       glXWaitX may or may not flush the GL stream.

ERRORS
       GLXBadCurrentWindow  is  generated  if  the drawable associated with the
       current context of the calling thread is a window, and that window is no
       longer valid.
