            function drawCanvas() {
                // Get first canvas element and its context
                var canvas = document.getElementById("square");
                var context = canvas.getContext("2d");
                context.beginPath();
                polygon(context, 6, 365, 53, 50, Math.PI/6);
                polygon(context, 4, 365, 53, 20, Math.PI/4);
                context.fillStyle = "#ccc";
                context.strokeStyle = "#008";
                context.lineWidth = 5;

                context.fill(); // Fill the path
                context.stroke();
            }

If we test it under Chrome, th centor square is filled, unless we draw the 
centor square counter clockwise. But under IE, it is un-filled
