_ICC_PROFILE isn't attached to "windows", it's attached to the
root window (more then one only if the root window is composed
on more than one monitor), or in the case of XRandR 1.2, the output
so there is a 1:1 correspondence between the number of monitors and the
number of profiles. The number of application windows doesn't come into it.
