You do everything correct, but you also need to tell the scrolled
window which "tile size" you have. Read everything about adjustment
in the reference of Gtk::ScrolledWindow (hope thats the correct
class gtkmm name). You may want to connect the adjustments to one
of your methods if the user moves the scrollers (and thus show
another part of your image).
