  the default)

Werner Robitza beedeb4399 doc/ffmpeg: mention both ffpreset/avpreset in documentation, remove superfluous example
ffmpeg looks for both .ffpreset and .avpreset files depending on whether the
-[avsf]pre or -pre option is used. Added two sections for each type of preset
including the rules according to which files are searched.

(Notably, the lookup order is swapped for avpreset files, because it first
looks for <codec>_<arg>.avpreset and then for <arg>.avpreset.)

This removes the section explaining -pre only, which was under "Examples",
where it did not really make sense.

Derek Buitenhuis 9db706206d doc: Consistently use 'filtergraph'
We used to use 'filtergraph' or 'filter graph' randomly.

'filtergraph' was chosen due to having 57 occurrences in
the documentation, whereas 'filter graph' had only 19.

Stefano Sabatini 18f43de964 doc/ffmpeg,ffmpeg-formats: avoid to mention ffmpeg options from formats.texi
Also extends documentation for timestamp related ffmpeg options, in order
to make more apparent the fact that muxer processing may change the
timestamps values.

Nicolas George cb2bd91413 ffmpeg: add the -canvas_size option.
Allows, amongst other things, to override the size guessed
by the sub2video hack.

Note: the -s option could have more or less the same semantic,
but it receives a special treatment by the options system.

Stefano Sabatini f185a040b0 doc/ffplay,ffmpeg: mention the corresponding negated option for -stats
This helps lazy users who didn't read the part about boolean options, in
case they grep for "-nostats".

-stdin and -stats are the only booleans option enabled by default. This
is a partial fix for Trac ticket #2332, a complete overhaul of boolean
options documentation is probably overkill.

Stefano Sabatini d11ac64ecf doc: replace '×' symbol with 'x'
Non-ascii chars are not correctly rendered in both MAN and HTML output or
may even cause compilation failure. Thus avoid to use them until we find
a satisfying way to deal with them.

Fix trac ticket #2243.

Stefano Sabatini b448677e6e doc: remove inclusion of libav* documentation in tools
This shrinks the tool manuals to a manageable size. Relevant manuals are
referenced in the "See Also" chapter.

Overall documentation inclusion should still be possible through the use
of a conditional variable set during configuration time, if someone feels
the need for a huge-wall-of-text-fashioned manual.
