Subject: Integrate SMAA and rework post process chain for better visual
 quality Add SMAA buffer generation passes Add quality levels for both FXAA
 and SMAA Separate gamma correction and tonemapping for effects that require
 linear-but-tonemapped inputs Move application of noise to final render pass
 to screen to avoid damaging other post process effects
