From 2c3d34c905fa6b831a066afae83b938de05eb241 Mon Sep 17 00:00:00 2001 From: Gareth Hughes Date: Sun, 18 Mar 2001 08:53:49 +0000 Subject: - Port 3.4 texture utils, texture format work to 3.5 (including new FetchTexel routines). - Initial hooks for GL_EXT_texture_filter_anisotropic. --- src/mesa/Makefile.X11 | 3 +- src/mesa/main/Makefile.X11 | 3 +- src/mesa/main/attrib.c | 3 +-
