Where does pandora get its gamma factor?

[Mark V. Meuer]

We just started adding people's pictures in place of the generic
user icons in the visual login and ran into a slight problem.  On a
couple of machines the images are too dim.  It looks like the gamma
factor for the screen is too low.

I know how to set the gamma factor when I'm logged in, but I was
wondering if there is a way to set it for pandora.  Any suggestions?
