Currently, we raise an error when doing this which breaks a conformance test from the OpenGL samples pack. Even if this is a bit silly it is not an error.
>From http://www.opengl.org/wiki/Rectangle_Texture: "Rectangle textures contain exactly one image; they cannot have mipmaps. Therefore, any texture parameters that depend on LODs are irrelevant when used with rectangle textures; attempting to set these parameters to any value other than 0 will result in an error."
