Translate virtualisation de l'interface utilisateur from French to English

– In Windows Presentation Foundation and Silverlight, a technique by which a subset of UI elements are generated from a larger number of data items based on which items are visible on the screen. Virtualization is a performance enhancement, because it is intensive, both in terms of memory and processor, to generate a large number of UI elements when only a few may be on the screen at a given time. ¹
