KeepUntilTransitionsFinished

An exit transition that keeps the old content composed until the whole transition has finished, instead of removing it when its own exit ends.

It animates nothing, so combine it with an exit: slideOutOfContainer(SlideDirection.Left) + KeepUntilTransitionsFinished, in either order.

Give both contents a ContentTransform.targetContentZIndex when using it: content interrupted on its way in and sent back out is held over the content arriving after it, and only the z-index decides which paints on top.
