Summary: PC-ALL: Brightness, Contrast, Gamma, maybe even Saturation.

Initial Comment:
Brightness, Contrast, Gamma, maybe even Saturation control gauges. I know I can increase them manually from the graphic's card driver but it's a real pain in the ass to keep doing it every time I enter a game. It would be nice to have it in scummVM's menu. Automagically detect if there's an ATI or nVIDIA card installed and tweak it in some way from within the application. 


eriktorbjorn suggested some sort of palette manipulation: "Well, since all palette operations go through the same function in the backend, you could probably add some sort of "brighten/darken the palette" filter there fairly easy, [...]"

And fingolfin replied: "SDL offers a SDL_SetGamma function, and we could add support for that. We can also artificially brighten the palette (though the result won't be nice)."

So what do you think ? :) Can it be done ? I think it could be useful.
