Is this a background page, or what?  Should we be waiting for onload?

This is the background page for the app. There isn't really anything useful to
do in onLaunched or any of the regular chrome.runtime events though.

The onWebFlow request fires whenever there is a call to
identity.launchWebAuthFlow from any app or extension.

+    frame: 'none',
+    id: key,
+    minWidth: 1024,
+    minHeight: 768,
+    hidden: true
+  };
+  chrome.app.window.create('scope_approval_dialog.html', options,
+                           initializeWebFlow);
+
+  function initializeWebFlow(win) {
+    win.contentWindow.addEventListener('load', function(event) {
+      var windowParam;
+      if (mode == 'interactive')
+        windowParam = win;
+      win.contentWindow.start(url, windowParam);
+    });
+  }
+});
