My bad, sorry for misinformation. The old patch that broke fate was in fate,
next wasn't and I checked only end of fate tests (I wrongly assume that it
passes fate) but 32-bit VS 2017 hangs at 'fate-api-png-codec-param' an

The Bayer matrix 8x8 used in DITHER_COPY macro is table dithers[5].
Remaining dithers[] matrixes are generated from this matrix by
downshift or upshift.
This patch fixes dithers[6] and dithers[7] matrixes -- they were
too dark.

This patch uses dithering in DITHER_COPY macro only if
it was not used option '-sws_dither none'.
With option '-sws_dither none' it uses downshift.
For human eye dithering is OK, for video codecs not necessarily.
If user don't want to use dithering, we should respect that

Lately ffmpeg supports gray9/10/12 pixel formats.
This patch adds gray9/10/12 pixel formats to y4m.
It also moves gray16 to 'strict -1' section.
Please review.

If ffmpeg reduces bit-depth to 8-bit or more, it uses DITHER_COPY macro.
The problem is DITHER_COPY macro make images darker (on all planes).
In x265 project there is issue #365 which is caused by this DITHER_COPY bug.
I think it is time to fix -- there are more and more high bit-depth sources.
