Example values:
\begin{itemize}\itemsep=0pt
-\item{ 0.0 - only the bottom/right window is automaticaly resized}
+\item{ 0.0 - only the bottom/right window is automatically resized}
\item{ 0.5 - both windows grow by equal size}
\item{ 1.0 - only left/top window grows}
\end{itemize}
-Gravity should be real value betwwen 0.0 and 1.0.
+Gravity should be a real value between 0.0 and 1.0.
Default value of sash gravity is 0.0. That value is compatible with previous
(before gravity was introduced) behaviour of wxSplitterWindow.
\docparam{window2}{The bottom pane.}
\docparam{sashPosition}{The initial position of the sash. If this value is
-positive, it specifies the size of the upper pane. If it is negative, it is
+positive, it specifies the size of the upper pane. If it is negative, its
absolute value gives the size of the lower pane. Finally, specify 0 (default)
to choose the default position (half of the total window height).}
