for most applications, can be used in any order; for 3-field majority selection,
however, vertical processing has to be done first.

for chroma up-sampling, horizontal scaling, color-space conversion, and chroma
down-sampling. Note that only one of either horizontal scaling or color-space
conversion can be done at any one time., i.e., these operations are mutually
exclusive. The scaler coefficients are the same for both chroma and luma.

majority-select or median filtering; de-interlacing for chroma always uses median
