title: How do I define line height with Prawn when generating a pdf in rails app?
body: <p>I am using prawn to generate a pdf.  So far everything has been rather straight forward.  I am having a problem defining the leading between lines of text.
  For example: when using a text_box</p>
  
  <pre><code>pdf.text_box "Ipsum dolor sit amet consectetue?",
    :width    =&gt; pdf.bounds.width - 10, :height =&gt; 150,
    :overflow =&gt; :ellipses
  </code></pre>
  
  <p>This will generate the text box except I can not find in the docs on how to control the spacing between lines of text.  The strings I will be using are typically 5 to 8 lines long.</p>
  
  <p>Thank you in advance</p>
