    mesa: Allow setting GL_TEXTURE_MAX_LEVEL to 0 with GL_TEXTURE_RECTANGLE.

    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."
