What happened to "drag-tiling"?

It looks like in the latest update one can no longer create copies of elements by dragging the extra box that used to show up in the lower right corner of selected background items? Since copy/paste wreaks havoc with z-order... is Roll20 going to have a way to easily fill an area with tiled graphics? The best option would probably be to have graphic fills for drawn items, but barring that, it seems we lost an existing functionality?

I'm pretty sure that the drag-tiling had to be removed as part of the new rendering engine. I believe that the plan is to return that feature eventually.
