Yeah this probably works. If you aren't putting a GtkLayout in a
scrolled window though, you may as well use GtkFixed.

GtkLayout is both a canvas and a drawing area. The only trick is that
you have to draw to layout->bin_window, and keep scrolling in mind
(layout->xoffset, layout->yoffset) if you care about scrolling.
