/**
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.
+Renderable and a tag to render it with and may also have Lighting, DepthTest
+and Blend states. Scenes can be used to further organize Renderables within a
+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
