Why does InsetGraphics say display() == true???

[Jean-Marc Lasgouttes]

In insetgraphics.h, I see
        ///
        bool display() const { return true; }

Why is that? includegraphics is certainly an inline thing (like a
simple character).

In userguide, there is a demo of an inline image, which is displayed
on screen, but perfectly inline in xdvi.

I propose to change the line above to
        ///
        bool display() const { return false; }

Juergen, I see you are the one who added it like that (in July 2000).
Did you have a reason for it?
