title: In pdf.js how do I turn on handtool as the default setting?
body: <p>I am using  <a href="http://mozilla.github.io/pdf.js/" rel="noreferrer">pdf.js</a> to display a <code>pdf</code>. I would like the handtool to be on as the default setting, rather than people having to access it via clicking on the button.</p>
  
  <p>This is the html button code:</p>
  
  <pre><code>  &lt;button id="toggleHandTool" class="secondaryToolbarButton handTool" title="Enable hand tool" tabindex="27" data-l10n-id="hand_tool_enable"&gt;
                &lt;span data-l10n-id="hand_tool_enable_label"&gt;Enable hand tool&lt;/span&gt;
              &lt;/button&gt;
  </code></pre>
  
  <p>This is the code on the .js document:</p>
  
  <pre><code>    var HandTool = {
    initialize: function handToolInitialize(options) {
      var toggleHandTool = options.toggleHandTool;
      this.handTool = new GrabToPan({
        element: options.container,
        onActiveChanged: function(isActive) {
          if (!toggleHandTool) {
            return;
          }
          if (isActive) {
            toggleHandTool.title =
              mozL10n.get('hand_tool_disable.title', null, 'Disable hand tool');
            toggleHandTool.firstElementChild.textContent =
              mozL10n.get('hand_tool_disable_label', null, 'Disable hand tool');
          } else {
            toggleHandTool.title =
              mozL10n.get('hand_tool_enable.title', null, 'Enable hand tool');
            toggleHandTool.firstElementChild.textContent =
              mozL10n.get('hand_tool_enable_label', null, 'Enable hand tool');
          }
        }
      });
      if (toggleHandTool) {
        toggleHandTool.addEventListener('click', this.toggle.bind(this), false);
      }
  
  toggle: function handToolToggle() {
  this.handTool.toggle();
  SecondaryToolbar.close();
   },
  </code></pre>
  
  <p>Can I add something to my html to turn that on immediately after page load? Or can I change the .js file to do that?</p>
