Most Recent Work: Cascaded Shadow Maps implemented.

Deferred Shading Implemented.

Blaze now has a deferred renderer with spherical volumes.
The unoptimized GBuffer is:
Position - R16G16B16A16 SFLOAT (3 channel position + alpha linear distance)
Albedo - R8G8B8A8 UNORM (3 channel color + alpha unused)
Normal - R16G16B16A16 SFLOAT (3 channel world space normals + alpha unused)
Physical Desc - R8G8B8A8 UNORM (R: Occlusion, G: Metallic, B: Roughness, A: Unused)
Emission - R8G8B8A8 SFLOAT (3 channel emission + alpha unused)

Added SSAO

SSAO has been added with 64 samples in a hemisphere, and 5x5 blur at half resolution. Next up to reduce the sample requirement by using low discrepancy samples.

Performance hit ~6ms at 1920x1080 full resolution SSAO.

Next up: Forward+/Clustered Forward renderer
