357			* - gamma correction is done using a LUT since that appears to work
358			* fairly fast.
359			* - If the input is chroma-subsampled (420/422), the yuv2rgb conversion
360			* (or rgb2yuv conversion) uses nearest-neighbour sampling to read
361			* read chroma pixels at luma resolution. If you want some more fancy
362			* filter, you can use swscale to convert to yuv444p.
