It already does, I believe.  The init code in XAS is tied exactly to the
size of your X11 screen (init.c excerpt follows):

                                        /* get root (full) screen size*/
   theight = DisplayHeight (display, screen_num);
   twidth = DisplayWidth (display, screen_num);
                                        /* screen size details        */
   Screen_Width = twidth - SCREEN_LEFT - SCREEN_RIGHT;
   Screen_Height = theight - SCREEN_TOP - SCREEN_BOTTOM;

and the uppercase constants are defined in xas.h:

   #define TEXT_SPACE      69

   #define SCREEN_LEFT     5
   #define SCREEN_RIGHT    5
   #define SCREEN_TOP     26
   #define SCREEN_BOTTOM   (5 + TEXT_SPACE)

You can always change the TEXT_SPACE key to a smaller number; the intent
was to allow a few lines from a terminal emulator window to peek through
at the bottom of the screen (or top) so you could still give some commands
and see what you were doing.

If you have a 1600 x 1200 screen, the size of XAS will be 1590 x 1100,
which should permit a 1k image to appear in full on the screen.
Unfortunately, we don't have a system that large here so I can't verify
that there isn't something else preventing this from happening.
