Fix Depth::GetLinear, be expressive about it for correctness before all, precompute these values later
Start fixing up dof https://files.facepunch.com/sam/1b2211b1/ombChoX97P.png
Iterate DoF
Smooth fade DoF from composite shader
Iterate dof, needs cleanup, almost perfect
Wave intrinsics to do early out for far dof
DoF2 Downsample with bias based on depth, cleanup

Front blur, tweaks
Final tweaks, add depth gap for adding an area where u might want more focus

Depth Resolve writes to both channels correctly
Final cleanups for dof2
