Members
`AggressiveDisposeAndCollectionOnLeavingViewPortBounds`	Removes the containers of items that have left the view shortly after each layout pass, as `VirtualizationScheme.DisposeOnLeavingViewPortBounds` does, then forces a full garbage collection. The least memory, at a real cost in smoothness; for very heavy item templates only.
`DisposeOnLeavingViewPortBounds`	Removes the containers of items that have left the view shortly after each layout pass; they are created again when the items come back. The selected item's container is kept.
`LightWeightCache`	Keeps every container once created. Scrolling back is fastest, and memory grows with how much of the list has been seen. The only scheme available while grouped.
