Maybe the widgets involved must be "realized" for recursive Show to
work? The allocation size might be needed correctly set. Maybe the image
is actually rendered but at a wrong place and size where it is not
visible. There are many ways to mess it up.

RAPID is a GUI generator thing, right? So it tries to manage the layout
by itself instead of using the prescribed techniques. Then Gtk_Fixed is
a way to go.
