+/**
+Top-level content class. Typically a Pipeline is used as the content
+Renderable for a View or effects such as ShadowMap or EnvironmentMap.
+
+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.
+
+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.
