Since these angles of rotation are called "transpose" in ffmpeg's other
filters (transpose, transpose_npp), shouldn't that be the name chosen
for this functionality?

It could then also use similar options.

Just wondering.

The filter(s) could also use some documentation (doc/filters.texi), but
the existing vaapi ones don't have any either, so *sigh*.

Cheers,
