[MPlayer-dev-eng] mga_vid and brightness/contrast control.

[Dariusz Pietrzak]

Hello,
 i've just commited changes that enable mga_vid to control brightness
in the same style that radeon_vid does
(echo "brightness=120" > /dev/mga_vid ).
 There should also be contrast control implemented, but all I know about
contrast is that neutral value is 0x80, and that this is '1.7 value
ranging from 0 to 1.99'.

What is '1.7 value'?

I am assuming that it means that first bit is 0 or 1, and the rest would
be integer from 0 to 99 ?
 This would look like BCD format, i thought BCD is long extinct?
