From 9a33a11d714c90162d32781ebbd2c1dfab52cfd1 Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Thu, 13 Jun 2002 04:28:29 +0000
Subject: New _mesa_debug() function to replace fprintf() calls. Some source
 files updated to call _mesa_debug(), but not finished. Added __GLimports as a
 parameter to _mesa_create/init_context() and updated drivers accordingly.
 Fleshed-out more of the __GLimports and __GLexports functionality. Removed
 run-time config file support (config.c)
