Wait until a mouse button is pressed.
::get_mbutton returns the coordinates of the mouse pointer in the output window and the mouse button pressed (Button):
Button = 1: Left button,
2: Middle button,
4: Right button.
The operator waits until a button is pressed in the output
window. If more than one button is pressed, the sum of the
individual buttons' values is returned. The origin of the
coordinate system is located in the left upper corner of the
window. The row coordinates increase towards the bottom, while the
column coordinates increase towards the right. For graphics
windows, the coordinates of the lower right corner are
(image height-1,image width-1) (see ::open_window,
::reset_obj_db), while for text windows they are
(window height-1,window width-1) (see ::open_textwindow).
::get_mbutton only returns if a mouse button is pressed in the window.
