+ * around it, and drawing is done in dw::core::Widget::drawWidgetBox.
+ *
+ * Ruler implements RegardingBorder; this way, it is simpler to fit
+ * the ruler exactly within the space between floats. Currently, the
+ * drawn area of the ruler is too large (but most of the superfluous
+ * part is hidden by the floats); this problem will soon solved here
+ * in the "dillo_grows" repository.
