CreateForAllAttachedMonitors ( ) : GDIContext
CreateForDefaultDisplay ( ) : GDIContext
CreateForDesktopBackground ( ) : GDIContext	Create a GDIContext so that drawing to the desktop can occur. On Vista, the drawing will be behind all windows, but will draw on top of any icons on the actual desktop. For Windows XP, the drawing will be behind those icons as well.
