/**
 * The GtkDrawingArea widget is used for creating custom user interface
 * elements. It's essentially a blank widget; you can draw on it. After
 * creating a drawing area, the application may want to connect to:
 *
 *  Mouse and button press signals to respond to input from
 *  the user. (Use gtk_widget_add_events() to enable events
 *  you wish to receive.)
 *
 *  The "realize" signal to take any necessary actions
 *  when the widget is instantiated on a particular display.
 *  (Create GDK resources in response to this signal.)
 *
 *  The "configure-event" signal to take any necessary
 *  actions when the widget changes size.
 *
 *  The "draw" signal to handle redrawing the
 *  contents of the widget.
 *
 * The following code portion demonstrates using a drawing
 * area to display a circle in the normal widget foreground
 * color.
 *
 * Note that GDK automatically clears the exposed area to the
 * background color before sending the expose event, and that
 * drawing is implicitly clipped to the exposed area.
 *
 * $(DDOC_COMMENT example)
 *
 * Draw signals are normally delivered when a drawing area first comes
 * onscreen, or when it's covered by another window and then uncovered.
 * You can also force an expose event by adding to the "damage region"
 * of the drawing area's window; gtk_widget_queue_draw_area() and
 * gdk_window_invalidate_rect() are equally good ways to do this.
 * You'll then get a draw signal for the invalid region.
 *
 * The available routines for drawing are documented on the GDK Drawing Primitives page
 * and the cairo documentation.
 *
 * To receive mouse events on a drawing area, you will need to enable
 * them with gtk_widget_add_events(). To receive keyboard events, you
 * will need to set the "can-focus" property on the drawing area, and you
 * should probably draw some user-visible indication that the drawing
 * area is focused. Use gtk_widget_has_focus() in your expose event
 * handler to decide whether to draw the focus indicator. See
 * gtk_render_focus() for one way to draw focus.
