contrast brightness level

Hi Toni,
don't you think that the difference of brightness and contrast between 0 and 1 or -1 is too high ??? There is no way for me control it quite precisely ?
I didn't test the last good version because i remember that you change it not so long, i think you remember when the change occur.
But if you need the last better version just tell me.
I just noticed that you can't see it really during the disk wait amiga boot picture, perhaps you set the levels with this ??
Just to show you : Alien Storm (1991)(U.S. Gold) sps quick-start amiga 500 (default)
1 (no changes)

2 brightness -1 (nothing else)

3 contract +1 (nothing else) i didn't forget to set back brightness to 0

ps: It's even like brightness -1 and contrast +1 seem do the same ???
I have the same results with any games.

Color component based gamma value calculation was wrong, it caused too dark image if contrast or brightness value was non-zero. Will be fixed in next beta.
