From 4e713913fb88bc221eea1a18822cc782ca39af4d Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Tue, 20 Jan 2004 15:24:50 +0000
Subject: Undo some bits from last check-in related to the
 ctx->Driver.NewTextureObject functions.  Don't allocate the driver-specific
 data during texture object creation but do it later as needed (as code
 originally was).
