A frame widget provides a top level container for other widgets and should
16
be your top most widget in the hierarchical tree just below the Stage.
17
This because using the Stage as the top most is not a good idea since
18
unlike a Frame, it is attached to the window, or a GTK embed and thus
19
cannot be transformed.
