*Way* less in the toolkit, though.  Look at your screen, and think
about the number of color lookups the toolkit would have to do
compared to the number of pixels in the window.

Well, if you want to do it on for the windows which care, your job is
already done.  The applications which do care about CM already manage
it internally.  No need to add anything else in the server or the
composite manager (which I've yet to see someone keep running after
the novelty has worn off).
