In any multi-head configuration, applications don't generally know what
screen their window will be presented on, so some default mechanism for
doing color correction seems required.

I'm already starting to figure out how to have applications cooperate in
the compositing process. This is currently being driven by needs for
accessibility, both color adjustment and magnification.  Perhaps this
kind of mechanism could be used for more accurate color correction.
