man page error - saturation is -10 through 10, not -100 through 100

[Chris Moore]

Binary package hint: mplayer

The man page says:

 hue[=hue:saturation]
  Software equalizer with interactive controls just like
  the hardware equalizer, for cards/:drivers that do not
  support hue and saturation controls in hardware.
   <-180-180>
    initial hue (default: 0.0)
   <-100-100>
    initial saturation, where negative values
    result in a negative chroma (default: 1.0)

but the range for saturation is -10 through 10, not -100 through 100.

Here's a patch to fix it:

confirmed on quantal on 2:1.0~rc4.dfsg1+

e.g. mplayer -vf hue=10:-20 SAM_0674.MP4 gives

The saturation option must be >= -10.000000: -20

and the man page still says:

       hue[=hue:saturation]
              Software equalizer with interactive controls just like the hardware equalizer, for cards/drivers
              that do not support hue and saturation controls in hardware.
                 <-180-180>
