Add Depth of field Blur

[nvanderploeg]

When aiming with focus at 70, The pin/aperture is blurry for most archers. Sometimes the target is blurry if they use the sight as the focal point, Would be cool to add blurs based on this

Good idea. There's probably some math out there that describes the type and "intensity" (for lack of a better generic term) of the blur for this scenario.
