This is going to change the full alpha channel of the pixbuf into a
one-bit mask, so will make the edges ragged if the PNG is antialiased.

Using Gtk::Image with GTK 2.0 is easiest, but I don't know when the
Perl bindings will be updated of if they are already.

Otherwise, try just drawing your pixbuf to a drawing area. See the
"scribble" chapter in the GTK tutorial to get the general idea, or the
demos that come with gdk-pixbuf.
