i doubt it helps much, but as i did some recent gamma work, could you please
try again?

@Henri:
if we add a wrapped driver entry point for XRRSetCrtcGamma the functions in
gdi32 would be able to choose that XRandr one. I'm not quite sure how it
chooses it, is it alphabetical or something like the last used driver?
The question is also if we then easily know on which display to change the
gamma...
