From 7dbafea860dace9bfad29760f8b756122bc9937a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 21 Feb 2011 15:11:44 -0700 Subject: [PATCH] st/mesa: fix incorrect texture size allocation in st_finalize_texture() If finalizing a non-POW mipmapped texture with an odd-sized base texture image we were allocating the wrong size of gallium texture (off by one). Need to be more careful about computing the base texture image size.
