Arguments: stream draw-fn erase-fn &optional scroll-p cursor first-corner
Similar to get-box, except that draw-fn is called each time the shape is to be drawn and erase-fn each time it is to be erased. draw-fn and erase-fn each have two arguments: the stream and the current box. When they are called, the stream brush will be set to one pixel-width black, the stream paint operation to invert. Thus, drawing the shape twice will suffice.
(get-box s) is equivalent to (get-shape-box s #'draw-box #'draw-box).
If scroll-p is true, the window (identified by stream) will be scrolled if the cursor moves outside it.
Note that the resulting box may be destructively modified later by the system, so if you want to keep it around, you should make a copy of it.
