I just meant implementing FRAME_WINDOW_P using the graphical window
system predicates instead of the terminal predicates; the same principle
you mentioned in the display-graphic-p thread.

Right, I was just mildly concerned since the comment by it mentions that
"it's defined to be the predicate for the window system being used",
which might not be good for code to rely on in the very long-term.

I removed that part of the comment in the patch series I just posted, is
that an acceptable change?
