Changing orientation causes multiple marks or causes mark to not be erased.

Hello!

Thanks so much for the work on this library -- it really looks great.

My app requires an orientation change mid-tour and it gets a little screwy when changing orientation while a mark is showing. In my app it causes whatever mark was showing to never disappear.

In the sample app if you go to the 'TransitionFromCode' screen and change orientation while a mark is showing, this is what you get:

Thanks again!
