A class of object similar to windows in that you can draw onto it but
it is never visible on the screen. Its contents, however, can be
copied onto a visible window use copy-stream-area. A bitmap-window (or
bitmap-pane)
has the functionality of a bitmap-stream hardwired into it,
implementing the backing-store for automatically refreshing and
redisplaying the window. Bitmap-stream is provided in case you want to
manage the drawings stored in memory independently. For an example
using bitmap-streams, choose the Help menu | CG Examples and look for
Bitmap-streams: custom backing store. Create bitmap-streams with
open-stream.
