     * To fix this, we take the x coordinate of the click within the button's bounds.
     * If you click the left edge of a 100 width button, then the x axis will be 0
     * and if you click the right edge then the x axis will be 100.
     * -------------
     * Then we divide the width of the button by 2 to get the center of the button and then get
     * the offset by subtracting the clicked x coordinate. Then we can apply that offset
     * to the x coordinate of the click relative to the screen to get the center of the
     * icon click.
