+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).

+\constfunc{bool}{Inside}{\param{int }{x}, \param{int }{y}}
+
+\constfunc{bool}{Inside}{\param{const wxPoint\& }{pt}}
+
+Returns {\tt true} if the given point is inside the rectangle (or on its
+boundary) and {\tt false} otherwise.
+
+
+\membersection{wxRect::Intersects}\label{wxrectintersects}
+
+\constfunc{bool}{Intersects}{\param{const wxRect\& }{rect}}
+
+Returns {\tt true} if this rectangle has a non-empty intersection with the
+rectangle {\it rect} and {\tt false} otherwise.
+
+
+\membersection{wxRect::IsEmpty}\label{wxrectisempty}
+
+\constfunc{bool}{IsEmpty}{}
+
+Returns {\tt true} if this rectangle has a width or height less than or equal to
+0 and {\tt false} otherwise.

+\membersection{wxRect::Offset}\label{wxrectoffset}
+
+\func{void}{Offset}{\param{wxCoord }{dx}, \param{wxCoord }{dy}}
+
+\func{void}{Offset}{\param{const wxPoint\& }{pt}}
+
+Moves the rectangle by the specified offset. If {\it dx} is positive, the
+rectangle is moved to the right, if {\it dy} is positive, it is moved to the
+bottom, otherwise it is moved to the left or top respectively.
