This is a major rewrite that improves the screen space raytracing a little bit. This also decouple ray preparation from raytracing to be reuse in other part of the code. This changes a few things: - Reflections have lower grazing angle failure - Reflections have less self intersection issues - Contact shadows are now fully opaque (faster) Unrelated but some self intersection / incorrect bad rays are caused by the ray reconstruction technique used by the SSR. This is not fixed by this commit but I added a TODO.
