  37  * Almost all the GLX API functions get routed through this dispatch table.
  38  * The exceptions are the glXGetCurrentXXX() functions.
  39  *
  40  * This dispatch table allows multiple GLX client-side modules to coexist.
  41  * Specifically, a real GLX library (like SGI's or the Utah GLX) and Mesa's
  42  * pseudo-GLX can be present at the same time.  The former being used on
  43  * GLX-enabled X servers and the later on non-GLX X servers.
  44  *
  45  * XXX Note that this hasn't actually been fully used yet in either Mesa or
  46  * the DRI.  Red Hat, however, has used it for their custom libGL.
