public enum WindowFrame:
Selects how a graphical window frame is produced.
NATIVE_FRAME keeps the operating-system decorations. KLYN_FRAME asks the native backend for an undecorated client surface and lets Klyn paint a default title bar and border. NO_FRAME also uses an undecorated native window, but Klyn does not paint any frame: the root widget occupies the complete client area.
window = MainWindow("Framing")
window.frame = WindowFrame.KLYN_FRAME
