A class of window that can be drawn on and which has a backing
store. It remembers its contents in an attached bitmap and
automatically redisplays them from that memory bitmap when required
(such as when the pane is hidden and then exposed). This is the
default-pane-class of the
bitmap-window. If you
want the whole image in a bitmap-pane to change, consider making the
change in the body of a with-delayed-redraw macro. That
macro handles bitmap panes specially and can be used to have the
redraw appear cleaner. See the with-delayed-redraw for an example.
