Detailed Description

A group node which serves as a root for weather layers.

This group node is the top level node in the scenegraph for weather layers. The node also serves as the main interface to create and modify weather layers. There is 1 geode under this node for drawing weather layer effects.

This class hooks into the simulation update which updates all active weather layer effects. Weather layer effects queue update jobs which are updated in parallel using a job splitter. There is also a post update for each weather layer for items that cannot use multithreading (currently intersection tests).

During scenegraph culling, this class calls cull methods on individual weather layers. If a weather layer effect is not culled, it submits a sort job to a job splitter and finally the queued sorting jobs are ran in parallel.
