RE: [GD-Windows] GetDeviceGammaRamp() is lieing to me

[Jon W. <hp...@mi...>]

I previously asked:

>  WORD userRamp[ 768 ];
>  HDC dc = CreateDC( "DISPLAY", 0, 0, 0 );
>  GetDeviceGammaRamp( dc, userRamp );
>  /* I'm not getting the actual ramp in effect here, but

Could it be that graphics cards somehow recognize our app as a 
"game" and purposefully lie to us about the current gamma 
settings, such that they can apply a special "game gamma" setting? 
If so, why does the operation of restoring the gamma (using data 
we initially read) go through to set the ramp (which is darker) and 
leave it like that when we quit? (we do restore in an atexit() 
handler).
