It was missing msurface_t reference which is (unnecessarily) required for light clusters computation
Also add more verbose debug names for dynamic models.
this is mostly copied from ray tracing gems 2 chapter 7 (Texture Coordinate Gradients Estimation for Ray Cones, by Wessam Bahnassi).
There's a weird bit about radians vs degrees. We'll figure it out later when the book becomes available.
An incorrect range of used vertices was pased into `VkAccelerationStructureGeometryTrianglesDataKHR`.
`maxVertex` was being set to a count of vertices per geometry, not a maximum used vertex number.
The fix is to track `vertex_offset` of the first used vertex, which makes `maxVertex` correct.
track brush models movement and update lights grid clusters with model transform and stuff
also implement animated textures for rtx
and also increase per-cluster lights limits
This is a massive hack, because we hardcoded some valve/lights.rad file
right into vk_rtx.c, and this is most certainly is not correct data. We
expect maps to have more custom rad file entries.

Also, emissive surfaces are no importance sampled, so it's noise fest.
This was an attempt to add map lighting w/o lightmaps. Unfortunately
there are just not enought of them to explain all light in maps. We're
missing something else. A lot of it.
we were mixing up row vs column major matrices
now RTX ray generation is fixes, and traditional rasterizer rendering
should also be projecting similar to gl render
this basically checks that acceleration structurs are building without
any vulkan errors (we still don't know whether they are bulding with
correct geometry though).
we also have compute shader pipeline ready for ray tracing (yay)
but it doesn't do any raytracing yet
Now each geometry is first allocated a slot with VK_RenderBufferAlloc,
and then VK_RenderBufferLock/Unlock are used to upload buffer contents.
This allow for two things:
1. Uploading buffer data to GPU memory on/after Unlock.
2. (Re)building BLAS for RTX on/after Unlock.
These buffers are now directly referenced by render_draw_t, which also
will be helpful in the future for both renderers.
Disable depth test and set dst blend factor to 1 for kRenderGlow mode.
Sprites are occluded in software.
(does this break any other code depending on Glow mode? who knows)
Now rendering submodules specify their colors and matrices using
VK_RenderState global stat api. This is a trade-off between making all
submodules track their state on their own, or managing that state
centrally.
not all beam types are supported yet
also changes studio api init sequence, fixes missing cvars
vertex type struct is no longer names as brush-specific
uniform buffer allocation is now in vk_render
blending issues still remain
