A GdkWindow is just a device for clipping drawing and capturing events. Most widgets
create their own GdkWindows to work in, and every "application window" contains lots
of GdkWindows. A GtkWindow is a widget used for a top level "application window", it
creates a GdkWindow as well as handling app window stuff like whether the app window
is resizable, which widget has focus, accelerator keys etc.
gdk_window_set_background sets the background pixel on a GdkWindow..
You can test if a widget has it's own GdkWindow, or if it uses the one the parent
widget has by using GTK_WIDGET_NO_WINDOW (widget)
You can get the GdkWindow used by a widget by accessing widget->window (the widget has
to be realized)
