* This is really an empty widget, the HTML parser puts a border
* 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.
