Native pp filter is available.

postproc dependency is also dropped from mp wrapper since it was the

hqdn3d was meant to be a more efficient denoise3d filter, is supported

This is following 568c70e7.

Native geq video filter is now available.

lavfi/f_setpts.c should allow everything mp=fixpts supports, with a lot

The native tile video filter is now feature equivalent.

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.

All the rectangle features have been ported to the native drawbox filter,
which has an equivalent syntax.

The filter has been ported to a native libavfilter filter.

Same functionality is provided by libswscale.

Most of the code was taken from MPlayer's vf_uninit_filter_chain.

This will allow us to do regression tests on libpostproc.

The delogo filter has been natively integrated into libavfilter,
simplify.

The source was natively integrated into libavfilter, with the name
mptestsrc.

This way it's easier for the programmer to look-up for a specific
symbols (e.g. for checking if it's unused).

The gradfun filter was already integrated natively in libavfilter.
Both filters issue the same output, and have a comparable performance.
