### LineLayout ### =========================================================================== DESCRIPTION: This example shows how to implement a document-browser-like-interface as a flow layout subclass, and using automatic invalidation on bounds change to implement the 'scale center cell' effect. It also implements a layout-level method to adjust the scrolling final position so the final cell will always be centered. =========================================================================== CHANGES FROM PREVIOUS VERSIONS: Version 1.0 - First version. =========================================================================== Copyright (C) 2012 Apple Inc.
