\begin{methoddesc}{overlay}{destwin\optional{, sminrow, smincol,

dminrow, dmincol, dmaxrow, dmaxcol}}

Overlay the window on top of \var{destwin}. The windows need not be

the same size, only the overlapping region is copied. This copy is

non-destructive, which means that the current background character

does not overwrite the old contents of \var{destwin}.

To get fine-grained control over the copied region, the second form

of \method{overlay} can be used. \var{sminrow} and \var{smincol} are

the upper-left coordinates of the source window, and the other variables

mark a rectangle in the destination window.

\end{methoddesc}

\begin{methoddesc}{overwrite}{destwin\optional{, sminrow, smincol,

Overwrite the window on top of \var{destwin}. The windows need not be

the same size, in which case only the overlapping region is copied. This copy is

destructive, which means that the current background character

overwrites the old contents of \var{destwin}.

To get fine-grained control over the copied region, the second form

of \method{overwrite} can be used. \var{sminrow} and \var{smincol} are
