Author: Paul Berry <[email protected]> Date: Sat Dec 29 11:31:37 2012 -0800 i965: Fix glCompressedTexSubImage2D offsets for ETC textures. This patch fixes intel_miptree_unmap_etc() (which decompresses ETC textures to linear) to pay attention to map->x and map->y when writing to the destination image. Previously these values were ignored, causing the xoffset and yoffset parameters passed to glCompressedTexSubImage2D() to be ignored.
