When the window size exceeds the canvas's scroll region,
 the whole canvas is centred in the window. Annoying, but normal.

connect to the size_allocate signal of the canvas, and when it is changed
change the scroll region and the "x2" and "y2" arguments of the background
rectangle
gnome_canvas_item_set (item, "x2", (double)whatever, "y2", (double)
whatever, NULL);
