Arguments: stream start-position &optional scroll-p cursor
Waits until the user presses or unpresses a mouse button, and then returns the current position of the mouse cursor in the stream coordinates of stream. During the wait, a rubber-band line is continuously drawn between start-position and the current mouse position. If scroll-p is true, the window (identified by stream) will be scrolled if the cursor moves outside it. Sets the stream cursor to cursor while running. If the cursor argument is unspecified or t, a default is used (typically the cross-hair cursor).
