## Detailed Description

Collection of renderables by priority.

Remarks:
  This class simply groups renderables for rendering. All the renderables contained in this class are destined for the same RenderQueueGroup (coarse groupings like those between the main scene and overlays) and have the same priority (fine groupings for detailed overlap control).

  This class can order solid renderables by a number of criteria; it can optimise them into groups based on pass to reduce render state changes, or can sort them by ascending or descending view depth. Transparent objects are always ordered by descending depth.

  To iterate over items in the collections held by this object you should retrieve the collection in use (e.g. solids, solids with no shadows, transparents) and use the accept() method, providing a class implementing QueuedRenderableVisitor.
