Arguments: stream start-position draw-fn erase-fn &optional scroll-p cursor
Performs a "rubber band" operation where the user drags a stretching line that is drawn on stream between start-position and the current mouse cursor position. If the function draw-line is passed as the draw-fn and erase-fn, then get-shape-line will act just like get-lineget-line and do a simple rubber-banding. If a fancier sort of rubber-band line is desired, custom functions can be passed in instead. The draw-fn and erase-fn should each take three arguments: the stream, the start-position, and the mouse-cursor position.
If scroll-p is true then the window will scroll if possible when the user moves the mouse cursor off the side of the window.
If cursor is true, it should either be a mouse
cursor to use during the rubber banding or t to default to cross-cursor. The
default is t.
