It can handle realize and configure events.  So it is useful
for quick and dirty custom display `widgets' when one
creates a GtkDrawingArea, connects something to "expose-event"
and that's it.

Of course, if you make a real widget (with its own class and
everything) it makes little sense to base it on
GtkDrawingArea instead of GtkWidget (or other suitable
parent).
