Since GDK in gtk 2.0 gives you a 32-bit coordinate space for GdkWindows,
you could probably just create the canvas as one big GdkWindow. For
scrolling, just pack it inside a viewport. This would allow the canvas to
not worry about scrolling. If it hasn't already been done, the exposure
compression code in canvas should probably be removed, as that is handled
at the GDK level as well now.
