Clément Bœsch 768c47ec37 lavfi: remove mp=pp filter.
Native pp filter is available.

postproc dependency is also dropped from mp wrapper since it was the
only filter needing that dependency.

Clément Bœsch 9b8de93036 lavfi: add pp filter.
Ported from MPlayer. Original author is A'rpi, with various
contributions from Michael Niedermayer. The original documentation was
mostly written by Diego Biurrun. See the MPlayer history for full
credits.

The filter is under GPL like the original filter, even if it differs
quite a lot. There is not much point in making it LGPL since pp is under
GPL.

Clément Bœsch 526e2415bd lavfi/gradfun: support named options.
This breaks usage for out-of-range values.

Clément Bœsch 3bdd70fc66 lavfi/gradfun: reduce up limit for threshold.
This will prevent an overflow in the SSSE3 and MMX filter_line code:
delta is expressed as an u16 being shifted by 2 to the left. If it
overflows, having a strength not above 64 will make sure that m is set
to 0 (making the m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as a
blur filter.

Clément Bœsch fd3cdcaf5f lavfi: remove mp=denoise3d filter.
hqdn3d was meant to be a more efficient denoise3d filter, is supported
natively, and is faster on my computer thanks to the ASM optimisations.

Same calculation as for RGBA etc to create unpremultiplied output.
Useful for creating an intermediate "Mix/Effects bank", in vision mixer
(switcher) terminology.

Example command:

ffmpeg -i input.mov -vf
"[in]scale=iw:ih:interl=1,format=yuv420p[bg];movie=BBC_blocks_watermark.png,scale=iw:ih:interl=1,format=yuva420p[dog];movie=Kickabout_strap.mov,scale=iw:ih:interl=1,format=yuva420p[strap];[strap][dog]overlay=0:0[me1];[bg][me1]overlay=0:0,scale=0:0:interl=1[out]"
-b:v 3M -an output.mov

Nicolas George c437c251b8 lavfi/drawtext: implement more generic expansion.
The new expansion mechanism uses the %{...} notation.
For compatibility reasons, it must be enabled explicitly,
but a warning is printed if a conflict is likely to happen.

Clément Bœsch f53112b665 lavfi: remove hqdn3d libmpcodecs wrapper.
The native filter was ported from the MPlayer project when the mp
wrapper didn't even exist, and when mp=hqdn3d was added, it was already
obsolete.

Stefano Sabatini 19add3224f lavfi/scale: implement clever/insane parsing heuristic, and add a size option
If the first argument can be read as a video size, set that output size
in the scale. This allows to specify in a filtergraph scale=qcif or
scale=320x240.

This is not completely safe, for example in case of a typo in the video
size string the first argument will be read as the input width
expression, giving rise to a confusing comment.
