WebGLRenderer Class
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 webGLBatchs. So no need for Sprite Batches or Sprite Clouds. Don't forget to add the view to your DOM or you will not see anything :)

clearBeforeRender
Boolean
This sets if the WebGLRenderer will clear the context texture or not before the new render pass. If true: If the Stage is NOT transparent, Pixi will clear to alpha (0, 0, 0, 0). If the Stage is transparent, Pixi will clear to the target Stage's background color. Disable this by setting this to false. For example: if your game has a canvas filling background image, you often don't need this set.
