+;  * given margins. The proper way to use this function therefore is:
+;  *
+;  * 	- Hide the mouse
+;  * 	- Set the bounding box
+;  * 	- Place the mouse at the desired position
+;  * 	- Show the mouse again.
+;  *
+;  * NOTE2: When setting the box to something that is larger than the actual
+;  * screen, the positioning of the mouse cursor can fail. If such margins
+;  * are really what you want, you have to use your own cursor routines.
