Clément Bœsch	2d66fc543b	lavfi/gradfun: fix rounding in MMX code. 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 mmdelta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
