  21.      ggggllllGGGGeeeennnnAAAAssssyyyynnnnccccMMMMaaaarrrrkkkkeeeerrrrssssSSSSGGGGIIIIXXXX is part of the SSSSGGGGIIIIXXXX____aaaassssyyyynnnncccc extension.  This
  22.      extension provides a framework within which particular sets of OpenGL
  23.      commands can become "asynchronous" via specific further OpenGL
  24.      extensions.  Currently the SSSSGGGGIIIIXXXX____aaaassssyyyynnnncccc____ppppiiiixxxxeeeellll extension is the only such
  25.      defined extension.
  26.  
  27.      A marker for asynchronous commands is "in use" if it is the current value
  28.      of GGGGLLLL____AAAASSSSYYYYNNNNCCCC____MMMMAAAARRRRKKKKEEEERRRR____SSSSGGGGIIIIXXXX, or if it is associated with any asynchronous
  29.      command that has been issued but has not been queried using
  30.      ggggllllFFFFiiiinnnniiiisssshhhhAAAAssssyyyynnnnccccSSSSGGGGIIIIXXXX or ggggllllPPPPoooollllllllAAAAssssyyyynnnnccccSSSSGGGGIIIIXXXX.
  31.  
  32.      ggggllllGGGGeeeennnnAAAAssssyyyynnnnccccMMMMaaaarrrrkkkkeeeerrrrssssSSSSGGGGIIIIXXXX returns an integer n such that the markers n, n+1,
  33.      n+2, ..., n+s-1 are not previously reserved or in use, where s is the
  34.      value of _r_a_n_g_e.  ggggllllGGGGeeeennnnAAAAssssyyyynnnnccccMMMMaaaarrrrkkkkeeeerrrrssssSSSSGGGGIIIIXXXX also records that each of the
  35.      markers in the returned range is reserved.
  36.  
  37.      Note that the marker name space is never shared across contexts, as the
  38.      name spaces for texture objects and display lists may be.
