Note from Original Source:
need to set the number of tiles to draw on the screen. Most of the time
we need to draw an extra tile because we're displaying a half-tile, but
sometimes the offset is exactly at 0 and thus we don't need to draw a
tile offscreen that we'll never see. In fact, doing this fixes a bug
that could occur because we would be accessing map data that's outside the map
when we're at the very bottom of the map.
