    universal-access: Add "Locate Pointer" option
    
    Since [0] and [1], "locate pointer" is now in Mutter and works
    well under Wayland and X11.
    
    Once activated, the mouse pointer can be located on the screen
    by pressing the Ctrl key. Pressing Ctrl will cause an animation
    to appear briefly at the location of your pointer.

    Fixes #586
