NEXT STEPS

1-> SHADOWS 
    Shadows force real workload, repeatedly drawing meshes 
    <- dir light DONE 
    <-multiple lights DONE 
    <- PCF 
    <- good bias 
    <- bug fixes with like, maybe clipping plane?
    <- Point light 
    <- Spot Light 
2-> BETTER SCENES 
    Probably loading from gltf, maybe USD, to render whole environments 
3-> COMPUTE 
    Culling and perf improvements for the new workload 
4-> (~ish) At some point, we should clean up the interfacs between scene, renderer, etc, and use handles rather than ptrs

FUN STUFF:

Polish /refactor painful areas
What's bad?
1- Descriptor sets still -- too much distant action, need to unify the setup and ingestion part 
2- Shaders 
    a- include modified  # DONE 
    b- 
3- Object updates 
    Don't belong where thye are right now 
4- Basic structure of application
    Main shou;dn't be renderer 

get point shadows going: 

We're going to just keep adding shadow maps to the array. These will be huge. thats ok, eventually we'll atlas small lights. 
Steps
1- 
update shadow drawing code,  X
shadowmap image generaiton code, X
and shader code  X
to use like 24 shadowmaps and index in with the MATRIXOFFSET param.  X
2- Correctly read shadow cubemap 
3- reduce the image count usign atlases, add an atlas offset index to indexinfo_2 
4- multiple shadow samplers -- for each atlas range and cube type. (? not sure we need this?)
5- custom pcf (maybe just do poisson?)
