Well, Peter's question wasn't. But why you thought this intrigues me...
my own background in this area is sketchy enough that I am curious to find
out more about your thoughts. Even if your solution doesn't answer
Peter's question specifically, what related problems might your solution
apply to?

I am not seeing how ncurses library routines would allow one to
distinguish a graphical display from a character-cell display.

As I understand it, DISPLAY contains a display name... but what this has
to console targets eludes me. An empty DISPLAY could be construed as
indicating that X libraries should not be used, though it might be
appropriate to use a command line option to allow ncurses to be forced to
be used from an xterm.
While I find myself thinking I understand your terminology, I am not sure.
What is your definition of "console target" vs. "console environment"?

A library approach that was known to be portable and was designed to
address this problem might well be the best solution. I am just
scratching my head trying to see how your suggestion applies.
