Transition to and from Fullscreen

Sorry, should know better.

Mac Sierra with LC 7.1.3

Going fullscreen true first hides the entire window, then the backdrop appears, and then the window itself.  Just how ugly that is depends what is present in the background.  If the backdrop appeared first, things would look better.

In fact, if you preset the backdrop so that isn’t a change between states, two out of three or four transitions look OK, and then there will be one with a nasty flash.
