Support non-looping PathView

ListView and PathView allow many different types of views, but there are times when it would be nice to use the unique features of PathView (e.g. non-linear or non-uniform layout) in a fixed end fashion, and vice-versa (i.e. a ListView that loops it's data).

It would be nice if such options were supported, or if a different abstraction could be added to support these use cases.
