our gradfun test is renamed to gradfun-ubitux as its name conflicts and
it was requested to be kept. Feel free to rename, change, finetune ...

There is no noticable benefit for such precision.

Current dithering only uses the first 4 instead of the whole 8 random values.
Signed-off-by: Anton Khirnov <anton@khirnov.net>

Current code divides before increasing precision.

Also reduce upper bound for strength from 255 to 64.  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.

First DC is only used once otherwise. This also makes the code

Instead of this it would be possible to change the code to support
larger K but that would make the code slower and probably still need
checks on K.
This variant is choosen as there are no known valid files that need
larger K
