This shows a bug (test from http://developer.mozilla.org/samples/canvas-tutorial/2_6_canvas_beziercurveto.html):

<canvas>
    <drawview>
        <method event="oninit">
            this.beginPath();
            this.moveTo(75,40);
            this.bezierCurveTo(75,37,70,25,50,25);
            this.bezierCurveTo(20,25,20,62.5,20,62.5);
            this.bezierCurveTo(20,80,40,102,75,120);
            this.bezierCurveTo(110,102,130,80,130,62.5);
            this.bezierCurveTo(130,62.5,130,25,100,25);
            this.bezierCurveTo(85,25,75,37,75,40);
            this.fill();
        </method>
    </drawview>
</canvas>
