This is just a small project I made to test motion of a camera (I began earlier testing in my game, "Ascent" and "Multiple Gravities"), and I think I have found the best way to do it. I also never really tried scrolling. So here it is. All me, of course. If I wanted, I could probably do this along the y axis as well, but I was too lazy to do both x and y here.
