 Top-level content class.  Typically a Sequence is used as the content
 Renderable for a View or effects such as ShadowMap or EnvironmentMap.
 
 A Sequence consists of a number of steps.  Each step is defined with a
-Renderable and a tag to render it with and may also have Lighting, Clipping,
-DepthTest and Blend states.  Scenes can be used to further organize Renderables
-within a step.

+step.
 
 PostProcessors can be applied after all of the steps in the Sequence have been
 processed.  Framebuffer objects are automatically used to pass render results
