[Openicc] wine monitor profiling [was: <kein Betreff>]

[Kai-Uwe Behrmann]

Welcome on list Pablo,

most profilers I tested use some way to adjust just the gamma curves on 
the window server. This is theoretical possible with linux too. But it 
would require some native X extensions. About the Colorvision instrument I 
dont know.

For most users, I am afraid, it will not be very practical. 
Nethertheless it would be nice for testers.

Good luck.


kind regards
Kai-Uwe Behrmann
