; The code uses segmentPixelOffset and the segment speed to figure out whether to draw the shifted sprite
; or the regular sprite. By AND-ing with the speed, if the result is 0, then we want a non-shifted sprite.
; If the result is non-zero, we want a shifted sprite. Then, we just need a per segment speed instead of a
; per position offset screen shift. Similarly, the same result can be used to figure out whether we need
; to increment/decrement the screen offset when updating segment position.
