## graphical-stream

This non-instantiable class is the superclass of all stream classes onto which graphics can be drawn. This includes windows (instances of `basic-pane` and its subclasses), the screen (whose class is `screen`), `bitmap-stream`, and `printer` streams. The class may be useful for specializing methods that should apply to any stream on which graphics can be drawn.

A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.
