Tweak visibility logic for inflated view scenarios

Previously, Visibility would determine whether a given view was
worthy of a transition by checking the visibility of that view's
parent hierarchy. This is done to avoid fading every view in
a hierarchy when only the top-most node should be faded.

However, the logic was flawed because it assumed the end scene
parent was stable between scenes, which is not the case with inflated
layout scenes, in which the parent views are not the same, even though they
may represent the same parents (via ids).

The new approach is to check information on both the start and end scene
parents, and to take ids into account when checking the state of these
parents in the start/end scenes. Also, avoid this logic altogether if the
transition is targeted at specific views (don't bother checking the
parents if the transition was told to fade specific views).
