Hmm. this was the style I just copied to find the access size for the meta_tex_image patch. Do we need to filter out no-op glTexSubImages in the driver backend or will the core? At the moment, it looks like this request will be passed along and processed by the drivers. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
