Usually, you don't want to scroll by a tile, but rather by a single pixel.
In which case it is usually more efficient to shift the whoel thing by one
pixel and then redraw only the necessary part. If you have a bunch of moving
sprites, though, sometimes it's more efficient to redraw the whole thing.
