/** A widget which indicates progress visually.
 *
 * The Gtk::ProgressBar is typically used to display the progress of a long
 * running operation. It provides a visual clue that processing is underway.
 * The Gtk::ProgressBar can be used in two different modes: percentage mode
 * and activity mode.
 *
 * When an application can determine how much work needs to take place (e.g.
 * read a fixed number of bytes from a file) and can monitor its progress,
 * it can use the Gtk::ProgressBar in percentage mode and the user sees a
 * growing bar indicating the percentage of the work that has been
 * completed. In this mode, the application is required to call
 * set_fraction() periodically to update the progress bar.
 *
 * When an application has no accurate way of knowing the amount of work to
 * do, it can use the Gtk::ProgressBar in activity mode, which shows
 * activity by a block moving back and forth within the progress area. In
 * this mode, the application is required to call pulse() perodically to
 * update the progress bar.
 *
 * There is quite a bit of flexibility provided to control the appearance of
 * the Gtk::ProgressBar. Functions are provided to control the orientation of
 * the bar, optional text can be displayed along with the bar, and the step
 * size used in activity mode can be set. 
 *
 * The ProgressBar widget looks like this:
