+ * @brief The StyleDialog class
+ * A list of CSS selectors will show up in this dialog. This dialog allows one to
+ * add and delete selectors. Elements can be added to and removed from the selectors
+ * in the dialog. Selection of any selector row selects the matching objects in
+ * the drawing and vice-versa. (Only simple selectors supported for now.)
+ *
+ * This class must keep two things in sync:
+ * 1. The text node of the style element.
+ * 2. The Gtk::TreeModel.
