fixed childLayoutString to work. made images capable of fitWidth. fixed animating data field pres changes. fixed lightbox to ignore annotations on collections. fixed double-click on icon to open in lightbox. added options for turning off ink labels, and opening ink in lightbox. fixed closing ink strokes by dragging. fixed drawing ink to use coord sys of starting point and to render ink the correct width and to honor GestureOverlay mode properly. .
