/*
* 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.
*
* NOTE: 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
* 2002/06/28 - added _glapi_set_warning_func(), Mesa 4.1.
* 2002/10/01 - _glapi_get_proc_address() will now generate new entrypoints
* itself (using offset ~0). _glapi_add_entrypoint() can be
* called afterward and it'll fill in the correct dispatch
* offset. This allows DRI libGL to avoid probing for DRI
* drivers! No changes to the public glapi interface.
* This code was originally general enough to be shared with Mesa, but
* they diverged long ago, so this is now just enough support to make
* indirect GLX work.
