16 This function can be useful to prevent having two mouse pointers on the
17 screen at the same time when running your program in windowed mode and
18 drawing the mouse pointer yourself. Other possible uses include the
19 ability to pause your game when the mouse goes off of the window, or
20 only scrolling the view when the pointer is near the edge of the win‐
21 dow, but not while off of the window.
