handle drawing 16*4 = 64 pixels

Previously we'd only drawn 8*5 = 40 pixels.

Current contents of data.img:

  (
    (globals . (
      (hline . (fn () (screen y) (hline1 screen y 0 (width screen))))
      (hline1 . (fn () (screen y lo hi) (if (>= lo hi) () ((fn () (pixel screen lo y 12) (hline1 screen y (+ lo 1) hi))))))
      (vline1 . (fn () (screen x lo hi) (if (>= lo hi) () ((fn () (pixel screen x lo 12) (vline1 screen x (+ lo 1) hi))))))
    ))
    (sandbox . (vline1 screen 5 0 (height screen)))
  )
