This improves results after FF_API_LAVF_BITEXACT=0. It still doesn't
pass, because of mov rtphint track which I don't understand (yet).

They picked up defaults, which changes from 128 to 200 when we remove
FF_API_OLD_AVOPTIONS.

Fixes associated fate tests when FF_API_MV0=0.

This filter can be used to scale one stream to match another or based on
another, useful to scale subtitles or other things to be overlayed

The h264 decoder reports 4.1 as its maximum level, but it will decode
5.1 4K video just fine. In practice, the published level limits in
vdpau do not communicate anything that's actually useful.

Use sizeof(void *) as its value, because AVFilterBufferRef is deprecated.

The value of wrap_flag in the Text Wrap Box specifies if the text is to
be wrapped or not. Uses 'end of line wrap' amongst the wrap styles
supported by ASS if the text is to be wrapped, i.e; fill as much text
in a line as possible, then break to next line.

The 3GPP spec has no provision for smart wrapping.

Use impersonal form, drop capitalization and ending dot.

Consistently use impersonal form.

The description is yet crappy, it merely copies the description of the
added and undocumented options and their value range. More descriptive
documentation is welcome.
