It was removed in 62447248.

Force re-generation of the manuals when an included file is modified.
The current dependency generation system is enable to track nested
inclusions.

The drawback is that the files will be generated even when there is no
strict need (for example if filters.texi is modified, ffmpeg.1 is
rebuilt), thus it trades a false negative with a false positive.

The existing implementation had little to do with VC1.
This could be implemented by adjusting the reference frames
ithemselfs but that would make frame multi-threading difficult.

Both don't change anything in the context between frames.

Address trac ticket #2431.

Prevent 0xFE and 0xFF from being considered the start of
non-standard 7-bytes sequences. No noticeable effect on speed.

Fix checkheaders when vid.stab is not available.

The frame must be writable if the show option is set, otherwise pass the
frame unchanged.

vidstabdetect and vidstabtransform common functions for interfacing
vid.stab are in libavfilter/vidstabutils.c

Make clear that the options accept an expression.

Honour declaration order in filter implementation, for shorthand
consistency.

The sample is already included in the FATE suite, but is not tested
because cropping wasn't fully supported before.
