Detailed Description

CompositorPassShadows This class enables force-updating multiple shadow nodes in batch in its own pass.

This is useful because shadow nodes may "break" a render pass in 3:

- Normal rendering to RT
- Shadow node update
- Continue Normal rendering to the same RT

This is an unnecessary performance hit on mobile (TBDR) thus executing them earlier allows for a smooth:

- Shadow node update (all of them? Up to you)
- Normal rendering to RT

Don't forget to set shadow nodes to reuse in the pass scene passes or else you may overwrite them unnecessarily
