Detailed Description

RenderStage base class.

Used for encapsulate a complete stage in rendering - setting up of viewport, the projection and model matrices and rendering the RenderBin's enclosed with this RenderStage. RenderStage also has a dependency list of other RenderStages, each of which must be called before the rendering of this stage. These 'pre' rendering stages are used for advanced rendering techniques like multistage pixel shading or impostors.
