+
+  The Fl_Round_Button subclass displays the "ON" state by
+  turning on a light, rather than drawing pushed in.
+
+  The default box type is FL_NO_BOX, which draws the label w/o a box
+  right of the checkmark.
+
+  The shape of the "light" is set with down_box() and its default
+  value is FL_ROUND_DOWN_BOX.
+
+  The color of the light when on is controlled with selection_color(),
+  which defaults to FL_FOREGROUND_COLOR (usually black).
