title: How to force user to use the "square" camera filter when taking a picture
body: <p>I have been looking all over the internet but I cannot find it. Is it possible for my app to leverage the "square" filter in the ios default camera app? Since it has all the functionality I would need (square, and pinch zoom) it would be nice to not have to make my own.I have tried all the different preferences for opening the camera but cannot seem to find it. Is there a library or category on the apple dev site that I might have missed?  Any guidance would help!</p>
