        * qkapow.h:

        1) I created a QCairoWidget which has a
        virtual void cairoPaint(cairo_t *)
        method which essentially replaces the QWidget::paintEvent. It's done
        essentially to enable people to just take the widget, stick it in their
        app and just use Cairo (either duble-buffered or not).
        2) Instead of the old demo code it uses now kapow. It's a little bit
        more attractive and nicely shows how to use QCairoWidget.
