 bounding box and the side bearings get
            cropped. If you pass ``0`` to both ``width`` and ``height`` and set
            ``contain`` to ``True``, it expands to the bounding box while
            maintaining the origin of the contours, meaning that LSB will be
            maintained but RSB won’t. The difference between the two becomes
            more obvious when rotate or skew transformation is applied.

        :Example:
            .. code-block::

                >> pen = FreeTypePen(None)
                >> glyph.draw(pen)
                >> pen.show(width=500, height=1000)
