Thanks for putting this together - it helped a lot! However, when I try to use this code, there seems to be a problem with scrolling while zoomed in. If I zoom in to an image and then try to scroll horizontally, it scrolls to the next slide without first scrolling completely to the edge of the zoomed in image. This makes it very difficult to view a zoomed in corner of an image.
I realize this uses an older version of the framework, so I also tried it with the Beta 14 and still the same problem.
Am I misinterpreting something? I would like to have the same behavior as the IOS photo browser. Specifically, I'm trying to be able to zoom in to an image and then scroll the entire image horizontally before scrolling to the next slide.
