Valid values are: - Anchor.TOP_LEFT - Anchor.TOP - Anchor.TOP_RIGHT - Anchor.LEFT - Anchor.CENTER - Anchor.RIGHT - Anchor.BOTTOM_LEFT - Anchor.BOTTOM - Anchor.BOTTOM_RIGHT You may also pass a tuple that indicates the position in percentages. For example, ``(0, 0)`` corresponds to "top left", ``(0.5, 0.5)`` to "center" and ``(1, 1)`` to "bottom right". This is basically the same as using percentages in CSS background positions.
