title: ImageList contain equal images rmagick
body: <p>I'm trying convert text to animated gif showing phrase letter by letter and when filling ImageList with images i just get List fill with equal pictures from last <code>text2.length.times</code> iteration. Why it is happening?</p>
  <pre><code>out= Magick::ImageList.new
  text2 = text2.fit 43 #&quot;Приехал я|, значится, из лагеря домой.\n&quot;
  temp_text=&quot;&quot;
  
  text2.length.times {
    |i|
  
    temp_text+=text2[i]+&quot;&quot;
     out[i]= (canvas.annotate(text, 0,0,0,62, temp_text) {
       self.fill = 'black'#'gray83'
      })
      # = canvas
  }
  out.length.times{
    |i|
  out[i].write(&quot;out#{i}.png&quot;)
  }
  </code></pre>
