* Reduce jitter artifacts in fog denoising by using view-relative reprojection matrix instead of converting to world and back * Reduce 27 taps to 8 trilinear samples for volume fog denoising * One degree fog TAA jitter and tighter blending * volume_fog_enable_jitter default disabled, we do it fine with just blue noise and TAA fixes * Henyey greenstein function was inverted, fix out of bounds access and fog not denoising right corner properly https://files.facepunch.com/sampavlovic/1b1811b1/sbox-dev_DNs0G1gaxA.mp4 * Henyey-greenstein phase funciton was still wrong, correct it, make actual fog density contribute to it https://files.facepunch.com/sampavlovic/1b2011b1/sbox-dev_456raQmbbj.png https://files.facepunch.com/sampavlovic/1b2011b1/sbox-dev_BnmMDwMeQx.png https://files.facepunch.com/sampavlovic/1b2011b1/sbox-dev_ruRvQQs1j1.mp4 * Able to tint fog volumes https://files.facepunch.com/sampavlovic/1b2011b1/sbox-dev_iiYXuyhrKQ.mp4
