title: Different colors on same 1pt line in iOS
body: <p>My app has a bunch of 1pt lines in it, and I've been going through and making sure none of them are positioned in a place where iOS anti-aliases the line. However, in the image below, even though the line isn't anti-aliased, it looks like it's drawing the left &amp; right border edges with a different shade of gray. What could be causing this?</p>
