why this  now? git cl lint?

I got a compilation error from one of the bots (possibly windows, I don't
remember now) about size_t being undefined.

Most likely it happened now because moving_average became the first include in
quality_scaler.h. It could perhaps be remoevd when I reorder the includes as you
suggest in your other comment.

But it seems reasonable to include stddef.h in every header file using size_t
(and not including anything else which surely should define size_t).
