From 6e963e965cd00d69de0d868882c2c5322b39f578 Mon Sep 17 00:00:00 2001
From: Felix Kuehling <fxkuehl@gmx.de>
Date: Thu, 25 Mar 2004 01:16:27 +0000
Subject: More state management changes: - Don't lock in savageDDUpdateStatte,
 don't call savageEmitHwStateLocked - Need to grab the lock for texture
 uploads now - New SAVAGE_NEW_CULL bit in new_state to make sure that culling
 state and   raster_primitive are not examined at the wrong times.
