There are some interesting problems here such as how do you determine
the size of the notebook if you can't size_request all its children.

This is pretty easy to do now, just put widget1 and widget2 in a vbox
or hbox and gtk_widget_hide() the one you aren't using and
gtk_widget_show() the other one.

Another way to do this is to put them in a notebook and turn off the
notebook tabs. (The advantage of the notebook way is that the
notebook's size will match the max size of both widgets.)
