New commits: commit f45cfc6569d2a5a81784284f294eb35e98211b19 Author: Ximeng Zu <[email protected]> Date: Fri May 19 23:15:28 2017 -0500 Update zoom constraints with device rotate Added function of updating zoom constraints whenever device rotates. This is achieved by calculating min zoom factor every time the size change function is called.
