/**
 * The GtkProgressBar is typically used to display the progress of a long
 * running operation. It provides a visual clue that processing
 * is underway. The GtkProgressBar 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 GtkProgressBar 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
 * gtk_progress_bar_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 GtkProgressBar 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 gtk_progress_bar_pulse()
 * periodically to update the progress bar.
 *
 * There is quite a bit of flexibility provided to control the appearance
 * of the GtkProgressBar. 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.
