ScreenPlay uses UI composition functionality that relies on the composition engine. This functionality is driven by the full Window Server. Therefore the full Window Server must be used in order to properly validate ScreenPlay adaptation components, such as EGL, or the multimedia framework at an early stage of product development. </p> <fig id="GUID-B33B7E76-5441-5404-BB62-910A351A7BD0"><title> |
