From 8c0ccce30038f5d28e74f7f4b5b5c0bbd8ac6dbe Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sat, 3 Nov 2012 20:49:35 +1000 Subject: st/mesa: add support for ARB_texture_cube_map_array (v2) This adds mesa state tracker support for the new extension, along with glsl->tgsi conversion to use the new opcodes where appropriate. v2: fix assert found running textureSize tests.
