/**
 * #GtkLayout is similar to #GtkDrawingArea in that it’s a “blank slate” and
 * doesn’t do anything except paint a blank background by default. It’s
 * different in that it supports scrolling natively due to implementing
 * #GtkScrollable, and can contain child widgets since it’s a #GtkContainer.
 * 
 * If you just want to draw, a #GtkDrawingArea is a better choice since it has
 * lower overhead. If you just need to position child widgets at specific
 * points, then #GtkFixed provides that functionality on its own.
 * 
 * When handling expose events on a #GtkLayout, you must draw to the #GdkWindow
 * returned by gtk_layout_get_bin_window(), rather than to the one returned by
 * gtk_widget_get_window() as you would for a #GtkDrawingArea.
