bottom border is moved farther down by ``dy``. (Note the the width and
height of the rectangle thus change by ``2*dx`` and ``2*dy``,
respectively.) If one or both of ``dx`` and ``dy`` are negative, the
opposite happens: the rectangle size decreases in the respective
direction.

The change is made to the rectangle inplace, if instead you need a
copy that is inflated, preserving the original then make the copy
first::

    copy = wx.Rect(*original)

", "
Inflating and deflating behaves *naturally*. Defined more precisely,
that means:

    * Real inflates (that is, ``dx`` and/or ``dy`` >= 0) are not
      constrained. Thus inflating a rectangle can cause its upper left
      corner to move into the negative numbers. (The versions prior to
      2.5.4 forced the top left coordinate to not fall below (0, 0),
      which implied a forced move of the rectangle.)

    * Deflates are clamped to not reduce the width or height of the
      rectangle below zero. In such cases, the top-left corner is
      nonetheless handled properly. For example, a rectangle at (10,
      10) with size (20, 40) that is inflated by (-15, -15) will
      become located at (20, 25) at size (0, 10). Finally, observe
      that the width and height are treated independently. In the
      above example, the width is reduced by 20, whereas the height is
      reduced by the full 30 (rather than also stopping at 20, when
      the width reached zero).
