true if the VirtualizingStackPanel is virtualizing; otherwise false.
In this context, the word "virtualize" refers to a technique by which a subset of user interface (UI) elements are generated from a larger number of data items based on which items are visible on-screen. Generating a large number of user interface (UI) elements when only a few elements might be on the screen at a given time is intensive with regard to both memory and processor. Through functionality that VirtualizingPanel provides, VirtualizingStackPanel calculates the number of visible items and works with the ItemContainerGenerator from an ItemsControl (such as ListBox or ListView) to create user interface (UI) elements only for visible items.
