+
+Returns the rectangle having the same size as this one but centered relatively
+to the given rectangle \arg{r}. By default, rectangle is centred in both

+\texttt{wxHORIZONTAL} flag, then it is only centered in this direction while

\func{void}{Deflate}{\param{wxCoord }{diff}}
\constfunc{wxRect}{Deflate}{\param{wxCoord }{dx}, \param{wxCoord }{dy}}
-Decrease the rectangle size by {\it dx} in x direction and {\it dy} in y
-direction. Both (or one of) parameters may be negative to increase the
-rectngle size. This method is the opposite of \helpref{Inflate}{wxrectinflate}.
-
-The second form uses the same {\it diff} for both {\it dx} and {\it dy}.
+Decrease the rectangle size.
-The first two versions modify the rectangle in place, the last one returns a
-new rectangle leaving this one unchanged.
+This method is the opposite from \helpref{Inflate}{wxrectinflate}:
+Deflate(a, b) is equivalent to Inflate(-a, -b).
+Please refer to \helpref{Inflate}{wxrectinflate} for full description.

+
\func{void}{Inflate}{\param{wxCoord }{diff}}
\constfunc{wxRect}{Inflate}{\param{wxCoord }{dx}, \param{wxCoord }{dy}}
-Increase the rectangle size by {\it dx} in x direction and {\it dy} in y
-direction. Both (or one of) parameters may be negative to decrease the
-rectangle size.
+Increases the size of the rectangle.
The second form uses the same {\it diff} for both {\it dx} and {\it dy}.
The first two versions modify the rectangle in place, the last one returns a
new rectangle leaving this one unchanged.
+The left border is moved farther left and the right border is moved farther
+right by {\it dx}. The upper border is moved farther up and the bottom border
+is moved farther down by {\it dy}. (Note the the width and height of the
+rectangle thus change by 2*{\it dx} and 2*{\it dy}, respectively.) If one or
+both of {\it dx} and {\it dy} are negative, the opposite happens: the rectangle
+size decreases in the respective direction.
+
+Inflating and deflating behaves ``naturally''. Defined more precisely, that
+means:
+\begin{enumerate}
+ \item ``Real'' inflates (that is, {\it dx} and/or {\it 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.)
+
+ \item 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).
+\end{enumerate}
