Valerii Zapodovnikov 6b1268f8c3 pixfmt: fixed wrong fix of comment This mostly reverts `785bfb1d7b`. But I also added some clarifications so that nobody mixes primaries with matrix again. SMPTE 240 and 170 primaires are the same, while matrix coeff. are different, because 240 is derived from 170's new primaries and white point while 170 uses BT.601 derived from BT.470 System M (yes, with Illuminant C) a.k.a. NTSC 1953. Some nits too. Reviewed-by: Reto Kromer <lists@reto.ch> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>		2021-06-02 17:30:24 +02:00
