% \begin{macro}{\autosetScreensizeWithMargins}
% If you want to get fancy, you can have this package automatically set the screen size
% to fit exactly n rows and m columns of the tiling. This may take some experimentation
% to get the width and height you want along with the effect. Adjust the scale (or width or height)
% parameter as needed. The arguments are
%\begin{enumerate}
%\item \texttt{\#1}: number of rows
%\item \texttt{\#2}: number of columns
%\item \texttt{\#3}: length of left margin
%\item \texttt{\#4}: length of right margin
%\item \texttt{\#5}: length of top margin
%\item \texttt{\#6}: length of bottom margin
%\end{enumerate}
% The latter four parameters are passed in that order to the \cs{margins} command of
% the web package. Standard values are, respectively, \texttt{.25in}, \texttt{.25in}, \texttt{24pt}, \texttt{.25in}.
%
% The \cs{autosetScreensizeWithMargins} command can only be used once in the preamble, and a design
% specification should not be made in the optional parameters of web.
