DOES IDISPLAY HAVE LAG WINDOWS
The SimpleDisplay abstracts all other devices that can be rendered to using a Windows Device Context such as printers and metafiles. The ScreenDisplay object abstracts a normal application window and implements scrolling and backing store. There are currently two Display objects: ScreenDisplay and SimpleDisplay. Each display manages its own DisplayTransformation object which handles the conversion of coordinates from real-world space to device space and back. A drawing surface is simply any hardware device, export file, or memory bitmap that can be represented by a Windows Device Context. The IDisplay interface abstracts a drawing surface. These objects allow you to render shapes stored in real-world coordinates to a screen, printer, or export file. The Display objects, those that implement IDisplay, are a set of objects which allow application developers to easily draw graphics on a variety of output devices. Provides access to members that control the Display.
