So, are you saying that the backing layer will always be the size of the view? Or that there there will always be enough tiles to cover the view?
If that is the case, then it sounds like what you are advocating is to create my own scroller or somehow tie the scroller to another (overlaid) view with a fixed frame but scrollable bounds, so that it only creates tiles (or a single CALayer) needed to display within its frame?
