/**
 * A GtkStatusbar is usually placed along the bottom of an application's
 * main GtkWindow. It may provide a regular commentary of the application's
 * status (as is usually the case in a web browser, for example), or may be
 * used to simply output a message when the status changes, (when an upload
 * is complete in an FTP client, for example).
 *
 * Status bars in GTK+ maintain a stack of messages. The message at
 * the top of the each bar's stack is the one that will currently be displayed.
 *
 * Any messages added to a statusbar's stack must specify a
 * context id that is used to uniquely identify
 * the source of a message. This context id can be generated by
 * gtk_statusbar_get_context_id(), given a message and the statusbar that
 * it will be added to. Note that messages are stored in a stack, and when
 * choosing which message to display, the stack structure is adhered to,
 * regardless of the context identifier of a message.
 *
 * One could say that a statusbar maintains one stack of messages for
 * display purposes, but allows multiple message producers to maintain
 * sub-stacks of the messages they produced (via context ids).
 *
 * Status bars are created using gtk_statusbar_new().
 *
 * Messages are added to the bar's stack with gtk_statusbar_push().
 *
 * The message at the top of the stack can be removed using
 * gtk_statusbar_pop(). A message can be removed from anywhere in the
 * stack if its message id was recorded at the time it was added. This
 * is done using gtk_statusbar_remove().
