FASTLED_FORCE_INLINE fl::u8 PixelController< RGB_ORDER, LANES, MASK >::loadAndScaleChannel ( fl::u8 c )

inline

One source channel, loaded, dithered and scaled – loadAndScale<SLOT> with RO(SLOT) replaced by a runtime channel index.

Same arithmetic, same tables: d[c] and premixed.raw[c] are indexed by source channel in both, which is what makes a colour order a pure permutation of these three values (FastLED#4402).
