Solari tracking issue

This is the tentative list of missing features/experimental ideas for Solari raytraced lighting.

Features:

• PointLight, SpotLight, and RectLight
• Transparent and alpha masked materials
• Skinned and morphed meshes
• Compute-shader/GPU authored meshes
• Visibility component support
• Decal support?
• Custom materials
• Depth of field support
• Docs

Quality:

• Light Sampling
  • Many local lights via NEE-AT or MegaLights
  • Separate local vs global light lists
  • Use EnvironmentMapLight in NEE, sample different mip levels
• Some kind of path guiding based on the world cache
• World Cache takes too long to go dark when lights turn off

Performance:

• Quarter res GI (stop tracing after NEE for some pixels)
• Path regularization
• Async compute BLAS/TLAS build (overlapped with primary view raster)
• Mipmaps
• LOD support for far away meshes
• Packed vertex formats and 16-bit BLAS
