Anyone have an example of using openInternalWindow to create a custom window frame instead of using the default as mentioned as a possibility in https://edvin.gitbooks.io/tornadofx-guide/content/part1/3.%20Components.html

Or is https://courses.bekwam.net/public_tutorials/bkcourse_flatwinapp_1.html the preferred way to do it? I noticed that DropShadow doesn't exist in the example and cannot be found for import.
