Perhaps an easy solution for mixing a graphics region and a
scrolling dialog region is to use starbase for the graphics
region and curses for the scrolling dialog region. The advantage 
of using curses (with normal writes) is of course portability
of this part of your application.
An important aspect of mixing graphics and alphanumeric
information in this way is to flush the starbase buffer at
the right moments by using make_picture_current.
Otherwise the graphics and alfa info could get "out of sync".
