This render stage implements the MWsGraphicsContext interface so that it can intercept

any drawing commands that draw an extended bitmap, any commands that draw a normal 

bitmap are just passed through to the next renderstage (along with any commands that

do not involve bitmaps at all).

A CNvgRenderStage object is created by a CNvgRenderStageFactory.
