/** Infinite scrollable area containing child widgets and/or custom drawing.
 *
 * Gtk::Layout is similar to Gtk::DrawingArea 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 directly
 * to a Gtk::ScrolledWindow), and it can contain child widgets, since it's a
 * Gtk::Container.  However if you're just going to draw, a Gtk::DrawingArea
 * is a better choice since it has lower overhead.
 *
 * When handling expose_event signals, you must draw to the bin_window
 * Gdk::Window - see get_bin_window() - rather than the normal Gdk::Window -
 * see get_window() - as you would for a drawing area.
