This method will allow the menu to be placed anywhere in the open
           window instead of just the upper left corner.

        Inputs:
            offset - This is the x,y tuple of the position that you want to
                move the screen to.

            mid - The offset will be treated as the value passed in instead of
                the top left pixel.

                'x' (the x point in offset will be treated as the middle of the
                      menu image)

                'y' (the y point in offset will be treated as the middle of the
                      menu image)

                'c' (the offset will be treated as the center of the menu image)
