HDR: Improve stars rendering
...
Previously we did not take into account the atmospheric transmittance
to render the stars, leading to stars being incorrectly rendered in
low visibility conditions.
Also place the stars in the correct render bin.

- Each face is rendered on a separate frame to help with performance.
- All faces are updated every 1.5 minutes. This can be changed through a

Use Uniform Arrays instead of Texture1D.
Use ambient/diffuse/specular/shininess material
properties consistently across all WS30 shaders.
Use consistent shading model for photoscenery vs.
landclass to minimize visual difference.

HDR: Optimize the G-Buffer and do not separate the occlusion texture
...
- The G-Buffer layout has been redesigned to be 96 bits per pixel. There are 24
unused bits that can be used for extra material parameters later (like
clearcoat).
- Add better debug views for the G-Buffer.
- Use octahedron normal encoding. This yields the same results as the previous
method but uses 16 bits less.
- Use rg11fb10f for the environment mapping cubemaps.
- Tweak the shadow mapping parameters and add a colored debug mode.
- Only render shadow maps for objects that inherit from model-default.eff or
model-pbr.eff instead of having a fallback Effect. Now transparent objects
should be ignored (if they are marked as such with model-transparent or
similar).
- Remove the separate occlusion texture. Now the PBR Effect expects a single
texture where R=occlusion, G=roughness and B=metallic.
