What follows is a replacement for the standard Interlisp
PAGEFULLFN.  PAGEFULLFN is called when a window fills up
with output; the standard function supplied with Interlisp
turns the window reverse-video and waits for you to type
a character.

Rather than reverse-video the window, which I find annoying, the
function below fills your window with a pattern which you define.
I happen to like a lightly speckled pattern which you can get by

    (SETQ PAGEFULL.TEXTURE (CREATETEXTUREFROMBITMAP (EDITBM))

and using the bitmap editor to create an 11x11 bitmap with a single
black dot in the middle.  Otherwise it has the same functionality
as the default PAGEFULLFN.  Enjoy....

          (* * Replacement for the system function that is called when output to a displaystream fills up the associated window.)

          (* * Actions: If the terminal input buffer is empty then we
fill the window with a distinctive pattern, wait till the user types
something, and then remove the pattern; else we just return because
the user has indicated we should pause.)
