/*
 * This file manages the OpenGL API dispatch layer.
 * The dispatch table (struct _glapi_table) is basically just a list
 * of function pointers.
 * There are functions to set/get the current dispatch table for the
 * current thread and to manage registration/dispatch of dynamically
 * added extension functions.
 *
 * It's intended that this file and the other glapi*.[ch] files are
 * flexible enough to be reused in several places:  XFree86, DRI-
 * based libGL.so, and perhaps the SGI SI.
 *
 * There are no dependencies on Mesa in this code.
 *
 * Versions (API changes):
 *   2000/02/23  - original version for Mesa 3.3 and XFree86 4.0
 *   2001/01/16  - added dispatch override feature for Mesa 3.5

 * Notes on dispatch overrride:
 *
 * Dispatch override allows an external agent to hook into the GL dispatch
 * mechanism before execution goes into the core rendering library.  For
 * example, a trace mechanism would insert itself as an overrider, print
 * logging info for each GL function, then dispatch to the real GL function.
 *
 * libGLS (GL Stream library) is another agent that might use override.
 *
 * We don't allow more than one layer of overriding at this time.
 * In the future we may allow nested/layered override.  In that case
 * _glapi_begin_dispatch_override() will return an override layer,
 * _glapi_end_dispatch_override(layer) will remove an override layer
 * and _glapi_get_override_dispatch(layer) will return the dispatch
 * table for a given override layer.  layer = 0 will be the "real"
