  29  * This file manages the OpenGL API dispatch layer.
  30  * The dispatch table (struct _glapi_table) is basically just a list
  31  * of function pointers.
  32  * There are functions to set/get the current dispatch table for the
  33  * current thread and to manage registration/dispatch of dynamically
  34  * added extension functions.
  35  *
  36  * It's intended that this file and the other glapi*.[ch] files are
  37  * flexible enough to be reused in several places:  XFree86, DRI-
  38  * based libGL.so, and perhaps the SGI SI.
  39  *
  40  * There are no dependencies on Mesa in this code.
