From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Tue, 8 Apr 2003 02:27:16 +0000
Subject: Added ctx->Texture._EnabledCoordUnits bitfield. Fixed some vertex
 array / vertex program glitches with glDrawElements. Fixed some fragment
 program runtime bugs. Non-trivial Cg programs are running now.
