If the scale has an origin (it will have one by default), GtkRange will render the two sides before/after the current value with different style classes, making it possible for themes to use different colors and properties for the two areas. This was possible in GTK 2 with style details, but got lost during the road to 3.0. https://bugzilla.gnome.org/show_bug.cgi?id=665140
