  53  * This dispatch table allows multiple GLX client-side modules to coexist.
  54  * Specifically, a real GLX library (like SGI's or the Utah GLX) and Mesa's
  55  * pseudo-GLX can be present at the same time.  The former being used on
  56  * GLX-enabled X servers and the later on non-GLX X servers.
  57  *
  58  * Red Hat has been using this since Red Hat Linux 7.0 (I think).
  59  * This'll be a standard feature in XFree86 4.3.  It basically allows one
  60  * libGL to do both DRI-rendering and "fake GLX" rendering to X displays
  61  * that lack the GLX extension.
