I was wondering how long it would take for someone else to notice that
the _ICC_PROFILE spec partially breaks on Xinerama.  As Sven points out,
the Xinerama concept itself is broken, but I think it's fair to say that
people with Xinerama either have:

1) a single main display and a number of "utility" displays, which are
not used for the work (but hold toolbars, documentation, etc).  In this
case the work display is a superior display, the utility displays might
be smaller LCDs.

2) a number of identical monitors, and a desktop which truely spans them
all.  In this case as the monitors are identical, the same display
profile should work.

I'll add a comment about Xinerama to version 0.2.
