 * A fake window with a big fat titlebar, a drop shadow around the edges, and an X close button in that titlebar.
 * Not draggable at the moment. Can't exceed the bounds of the containing window. In other words is worse than
 * a regular window in almost every possible way, except that it looks cooler and the same across platforms.
