This is the class of the screen. Calling type-of on the screen will return this symbol
rather than (as in earlier releases) an unpredictable gensymed name of
a subclass of this class (the name of this class was not exported in
releases prior to 6.0). If an application wishes to prepare for the
possibility of multiple screens, it may be best to test whether
something (named by object is the screen with a
form like
(typep object 'windows-screen-device)
rather than
(eq object (screen *system*))
See also screen.
