It does it in a super dirty way, trad renderer needs a massive
refactoring.
It also displays patched skybox, however, we need it to display the
oridingal one.
vk: rt: add workaround for holes in geometry
Once upon a time, there were some BLASes. There were the BLASes for dynamic geometry, that were to be used every frame to draw very dynamic things, like sprites and beams. They were initialized at the very begining of the renderer's lifetime, and were expected to live happily for the entire process duration. However, an evil NewMap appeared. It didn't care abount anything or anyone, so when it came, it just cleared all the allocators, and allowed other BLASes to be allocated into the same space as dynamic BLASes were already given. This made BLASes live on top of each other, use each others toys and make them fight. They weren't happy.
So we just kill them and creat them again from scratch, when the evil NewMap comes.
The end.
Fixes#729

Under `-vkvalidate` enables `debugPrintfEXT()` in shaders, allowing
extra validation and error reporting from shaders.
Severely degrades performance, so should be enabled only for debugging.
`throughput` should be scaled based on BRDF. I.e. diffuse bounces should
be scales by base_color at the very least.
This fixes lighting being too bright after 3-5 bounces.
Our gaussian blur is incorrect, as it doesn't preserve luminance, and
the final imaga ends up being darker than it should be.
Do a box blur as a simple test. It does result in a correctly looking
white furnace test image (modulo square blocks and luminance leaking).
Shoulnd't have multiplied by diffuse BRDF result. It should be encoded
in diffuse-vs-specular split, and the cosine term is already taken care
of in sampling.
Only engage soft particles/blending after a certain distance. Makes
certain see-beams-through-weapons visual glitches disappear.
Engages soft particles with a smoothstep so the don't immediately pop up
after a certain distance, rather appear gradually.
