352			* range of this RGB type. rgb2yuv is the exact opposite.
353			* - gamma correction is done using a LUT since that appears to work
354			* fairly fast.
355			* - If the input is chroma-subsampled (420/422), the yuv2rgb conversion
356			* (or rgb2yuv conversion) uses nearest-neighbour sampling to read
357			* read chroma pixels at luma resolution. If you want some more fancy
358			* filter, you can use swscale to convert to yuv444p.
