code: func (w *Window) Resize(width, height int) {
  	w.Configure(xproto.ConfigWindowWidth|xproto.ConfigWindowHeight, 0, 0,
  		width, height, 0, 0)
  }
docs: // Resize issues a ConfigureRequest for this window with the provided
  // width and height. Note that if width or height is 0, X will stomp
  // all over you. Really hard. Don't do it.
  // If you're trying to resize a top-level window in a window manager that
  // supports EWMH, please use WMResize instead.
