/** A widget displaying an image.
 *
 * The Gtk::Image widget displays an image. Various kinds of object can be
 * displayed as an image; most typically, you would load a Gdk::Pixbuf ("pixel
 * buffer") from a file, and then display that. 
 *
 * Gtk::Image is a subclass of Gtk::Misc, which implies that you can align it
 * (center, left, right) and add padding to it, using Gtk::Misc methods.
 *
 * Gtk::Image is a "no window" widget (has no Gdk::Window of its own), so by
 * default does not receive events. If you want to receive events on the
 * image, such as button clicks, place the image inside a Gtk::EventBox, then
 * connect to the event signals on the event box.
