  * Usually, you would not extend from this class directly, but would instead extend
  * from one of the core pipelines, such as the Multi Pipeline.
  *
+ * The pipeline flow per render-step is as follows:
+ *
+ * 1) onPreRender - called once at the start of the render step
+ * 2) onRender - call for each Scene Camera that needs to render (so can be multiple times per render step)
+ * 3) Internal flow:
+ * 3a)   bind (only called if a Game Object is using this pipeline and it's not currently active)
+ * 3b)   onBind (called for every Game Object that uses this pipeline)
+ * 3c)   flush (can be called by a Game Object, internal method or from outside by changing pipeline)
+ * 4) onPostRender - called once at the end of the render step
