reduz 9293bc3935 Implement more rendering options as specialization constants
* Shadow quality settings now specialization constant.
* Decal and light projector filters can be set.
* Changing those settings forces re-creation of the pipelines.

These changes should help improve performance related to shadow mapping, and allows improving performance by sacrificing decal and light projector quality.
