-- <description>
-- Gdk_Screen objects are the GDK representation of a physical screen. It is
-- used throughout GDK and GTK+ to specify which screen the top level windows
-- are to be displayed on. It is also used to query the screen specification
-- and default settings such as the default colormap (Get_Default_Colormap),
-- the screen width (Get_Width), etc.
--
-- Note that a screen may consist of multiple monitors which are merged to
-- form a large screen area.
