-/**
-Encapsulates all of the information used to produce a complete image in the
-framebuffer. This is the highest level rendering class.
-
-A Pipeline contains a sequence of passes. Each pass has a Renderable along
-with Lighting, Clipping, DepthTest and Blend states. Scenes can be used to
-organize Renderables within a pass. A Camera can be specified for the entire
-Pipeline.
-
-A Pipeline is also a Renderable itself. It will only respond to the default
-pass. The Renderables within the Pipeline will be invoked with whatever tags
-were specified when adding them.
-
-A Pipeline's render method should normally be called without a Renderer; it
-will create one itself, using the camera specified for the Pipeline. If a
-Renderer is passed, its camera will be used instead.
-
-PostProcessors can be applied after all of the passes in the Pipeline have been
-rendered. Framebuffer objects are automatically used to pass render results to
-the PostProcessors. High dynamic range and multisample rendering can be
-requested for increased quality.
