Draw two paths on the canvas; one green and one purple: Internet
Explorer 9, Firefox, Opera, Chrome, and Safari support the
beginPath() method. Note: Internet Explorer 8 and earlier
versions, do not support the <canvas> element. The beginPath()
method begins a path, or resets the current path. Tip: Use
moveTo(), lineTo(), quadricCurveTo(), bezierCurveTo(), arcTo(),
and arc(), to create paths. Tip: Use the stroke() method to
actually draw the path on the canvas. Your message has been sent
