This method allows the button to be moved manually and keep the click
        on functionality.
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Inputs:
            position - This is the x, y position of the top left corner of the
                            button. (defining point can be changed to midpoint)

            midpoint - If true is passed to midpoint the button will be blitted
                to a surface, either automatically if a surface is passed or
                manually, such that the position input is the center of the
                button rather than the top left corner.
