%RBBOX	Rubberband box.
%	RECTF = RBBOX(RECTI, XY) tracks a rubberband box in the current
%	figure, initialized with box RECTI, and starting the tracking at
%	the point XY.  The mouse button must be help down when RBBOX is
%	called.  RBBOX returns with the mouse up button event.  As a 
%	result, RBBOX can be used in an M-file, along with 
%	WAITFORBUTTONPRESS, to control dynamic behavior.
%	RECTF is the rect specified by the initial point of RECTI and its 
%	extent is determined by where the mouse up event occurs.
%	RECTI, XY, RECTF are in units of the current figure.
