title: Gridster auto resize by content height
body: <p>I am trying to append content inside a Gridster widget but with no luck for two days already. I tried with:</p>
  
  <pre><code>.resize_widget( $widget, [size_x], [size_y], [reposition], [callback] )
  </code></pre>
  
  <p>but the sizes x and y only accept numbers - its default re-sizing mechanism and they are not pixels. They are some sort of steps. If I increment with +1 the size_y the widget is re-sized more than needed and again with its own mechanism.
  I was also looking for a way to reduce this step. No luck.
  I also tried to change the widget height, min-height, etc. It was not re-sizing.
  Do you have any suggestions, ideas? </p>
