<div class="box intro">
<p>the WebGLRenderer draws the stage and all its content onto a webGL enabled canvas. This renderer
should be used for browsers that support webGL. This Render works by automatically managing webGLBatch's.
So no need for Sprite Batch's or Sprite Cloud's
Dont forget to add the view to your DOM or you will not see anything :)</p>
