/** Base class for horizontal or vertical rulers.
 *
 * NOTE this widget is considered too specialized/little-used for GTK+, and will in the future be moved to some other package. If your application needs this widget, feel free to use it, as the widget does work and is useful in some applications; it's just not of general interest. However, we are not accepting new features for the widget, and it will eventually move out of the GTK+ distribution.
 * Rulers are used to show the mouse pointer's location in a window. The ruler can either be horizontal or vertical. Within the ruler a small triangle indicates the location of the mouse relative to the horixontal or vertical ruler.

 * This is an abstract base for Gtk::HRuler and
 * Gtk::VRuler.  Users should only instantiate those types.
