Rather than raising the number of citizens show beside each other you should 
draw as many as you need overlapping (like in civ 2). That should be fairly 
simple to implement, just make one pixmap, and draw the number of heads you 
need with an offset from the left edge. In the gtk client something like:

int offset = MAX(one_citizen_sprite->width,
                        citizens_list_pixmap_width/num_citizens);
gdk_draw_pixmap(cityzens_list_pixmap, civ_gc, one_citizen_sprite->pixmap,
            0, 0,
            this_citizen_number * offset, 0,
            one_citizen_sprite->width, one_citizen_sprite->height );

Where this_citizen_number should run from 0.
