title: GWT: deferred loading of external JS resources
body: <p>I have a widget depending on some external JS files, and I'd like to lazy load all these external resources. I've already used code splitting to lazy load the GWT code that concerns the widget, but the JS files defined in the gwt.xml, using the <code>script</code> tag, are loaded anyway, which is not desirable.</p>
  
  <p>Is there a standard GWT way of loading these external resources on demand? I can do it myself using raw JS, but I'd rather not spend time on this too.</p>
