This is an uncommon usecase that would require too much effort to
support properly for the small amount of benefit.
X11 has an atom which stores one ICC display profile per screen. We
would have to change the display transform depending on which screen
each pixel shows up on. This would also mean that we'd have to deal
with the case where an image tile is split across two screens.
Again, this would be a lot of code (and, thus, the potential for a lot
of bugs). It would be infrequently used (and so the bugs would tend to
not be found as quickly). And it would likely slow down our common code
paths for little benefit.
