Pfft sorry for that abomination!
interface renderer {
void draw(rect[] rects);

class widget {
rect r;

This requires you to store the widget-renderer relationship outside the
widget. Since each widget has exactly one location where it lives, this
is awkward. Much better to just store the relationship on each widget.
