krzysztof narkowicz 31a4f9aecb Lumen - surface cache generation improvements ...

* Added r.MeshCardRepresentation.Debug for surface cache debugging. It skips DDC reads and writes, allows to regenerate per static mesh on demand and appends extra debug visualization data to every generated mapping
* Surfels are now weighted by opacity - ratio of rays which hit in a given cell, and by visibility - how many rays can hit a given Surfel from outside the mesh. This helps to select most important surfaces to cover when hitting limits
* Removed distance constraint. It�s no longer needed when card discontinuities are already handled inside the surface cache sampling code. This allows to generate larger and more optimal cards
* Limit max number of surfels to prevent generation time from exploding, as dense two sided meshes like large trees can generate many more surfels than simple walls
