    SetPointer -- Specify a pointer sprite image for a window.

    SetPointer( Window, Pointer, Height, Width, XOffset, YOffset )
                A0      A1       D0      D1     D2       D3

    VOID SetPointer( struct Window *, UWORD *, WORD, WORD, WORD, WORD );

    Sets up the window with the sprite definition for the pointer.
    Then, whenever the window is the active one, the pointer
    image will change to the window's version.  If the window is
    the active one when this routine is called, the change takes
    place immediately.

    The XOffset and YOffset parameters are used to offset the
    upper-left corner of the hardware sprite image from what Intuition
    regards as the current position of the pointer.  Another way of
    describing it is as the offset from the "hot spot" of the pointer
    to the top-left corner of the sprite.  For instance, if you specify
    offsets of zero, zero, then the top-left corner of your sprite
    image will be placed at the mouse position.  On the other hand,
    if you specify an XOffset of -7 (remember, sprites are 16 pixels
    wide) then your sprite will be centered over the mouse position.
    If you specify an XOffset of -15, the right-edge of the sprite
    will be over the mouse position.

    Window = pointer to the window to receive this pointer definition
    Pointer = pointer to the data definition of a sprite
    Height = the height of the pointer
    Width = the width of the sprite (must be less than or equal to sixteen)
    XOffset = the offset for your sprite from the mouse position
    YOffset = the offset for your sprite from the mouse position
