     'GtkLayout' is similar to 'GtkDrawingArea' in that it's a "blank
     slate" and doesn't do anything but paint a blank background by
     default. It's different in that it supports scrolling natively
     (you can add it to a 'GtkScrolledWindow'), and it can contain
     child widgets, since it's a 'GtkContainer'. However if you're just
     going to draw, a 'GtkDrawingArea' is a better choice since it has
     lower overhead.

     When handling expose events on a 'GtkLayout', you must draw to 
     GTK_LAYOUT (layout)->bin_window, rather than to  GTK_WIDGET
     (layout)->window, as you would for a drawing area.
