From 30f51ae067379c2b3573c06b707d25a9704df7be Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Tue, 18 Dec 2001 04:06:44 +0000
Subject: Replace old matrix stacks with new code based on struct matrix_stack.
 Moved vertex program hash table into shared context state. Implemented
 reference counting for vertex programs. Replaced tnl "ProjectedClip" with
 "Ndc" (normalized device coordinates).
