title: multiple font size in button text
body: <p>With this line</p>
  
  <pre><code>myButton.setText(Html.fromHtml("&lt;font color='red' size='50dp'&gt;First&lt;/font&gt;&lt;br/&gt;&lt;font color='blue' size='20dp'&gt;Second&lt;/font&gt;"));
  </code></pre>
  
  <p>The first line is indeed red, and the second line is blue, but I can't control the font size of either text line, what gives?  How can I do it?</p>
