title: insert image at specific point of paragraph
body: <p>*I have a Google Document with a string like "text {logo} text"
  How do place an image where {logo} is?
  So far I tried:</p>
  
  <pre><code>var logoElement = s.findText("{logo}").getElement();
  logoElement.getParent().insertInlineImage(0,logoBlob);
  s.replaceText("{logo}", "");
  </code></pre>
  
  <p>But this inserts the image <em>before</em> the found paragraph (or with 1: <em>after</em>). How do I place it <em>inside</em> the paragraph at the exact location?</p>
