lavfi/showspectrum: set default height to 512
...
Only power-of-two FFTs are supported; so to get a full spectrum
(that is, one up to Nyquist), the height must be a power of two.
Therefore, change the default height from 480 to 512.

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.

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.
