title: Navigation Drawer - Have only icons and very big
body: <p>I have a nav drawer implemented in my activity. The audience for my app is the elderly and I want the icons to be very large and take up the whole drawer height. </p>

  <p>I am looking to have the 4 icons evenly spaced out and to have no text just big icons. I have tried playing around with the tag:</p>
  
  <pre><code>&lt;dimen name="design_navigation_icon_size" tools:override="true"&gt;&lt;/dimen&gt;
  </code></pre>
  
  <p>but I have not been able to get it to work. The icons simply keep overlapping each other when they get too big near the top. The images always seem to be contained in the header layout.</p>
