GtkLayout
Infinite scrollable area containing child widgets and/or custom drawing
#GtkLayout is similar to #GtkDrawingArea 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 to a
#GtkScrolledWindow), and it can contain child widgets, since it's a
#GtkContainer. However if you're just going to draw, a #GtkDrawingArea
is a better choice since it has lower overhead.
When handling expose events on a #GtkLayout, you must draw to
GTK_LAYOUT (layout)->bin_window, rather than to
GTK_WIDGET (layout)->window, as you would for a drawing
area.
