I don't know enough about X to even parse the last sentence, but I do
think display-color-cells should return the number of distinct colors
Emacs can use.  It sounds like display-color-cells does that on every
platform except X (MS-Windows, MS-DOS, Unix tty, don't know about the
Mac).  That function is advertised as one that returns the number of
distinct colors, so IMHO it had better do what we say it does.
