I know you've already pushed this, but the thought just occurred to me
-- does this deal properly with texture views? I always get immensely
confused by those, but shouldn't the levels/layers be offset by the
texture object's minlayer/baselevel/minlevel somewhere? Possibly in
_mesa_CopyImageSubData?
