Actually fixed #22.

So I still have no idea why 4” doesn’t work, but I figured out the
problem with 3.5” accidentally. The problem was that the UIScrollView
was doing the wrong thing by default. Once I turned off “Adjust Scroll
View Insets” and reset all of the view behaviors to “inferred”, it
started playing nice. Credit to StackOverFlow for pointing the
UIScrollView anomaly out.
