From b80ec33f3559e9a14d08f84c8e369a0dc81b46d7 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Tue, 24 Nov 2009 10:28:27 +0800 Subject: mesa/es: Fix GL_OES_texture_cube_map support. Unlike in OpenGL, GL_OES_texture_cube_map says that all coordinates are changed the same time by the token GL_TEXTURE_GEN_STR_OES, and the initial mode is GL_REFLECTION_MAP_OES.
