How to customise \title to include a shadow effect on a paper?

The shadowtext package allows you to use the command \shadowtext to create a shadow behind the letters like so

\documentclass{paper}

\begin{document}
\maketitle
\end{document}


If, however, I want to break the title into two lines or more I can't use

\documentclass{paper}

\title{\shadowtext{Very long Title \\ is very long}}

\begin{document}
\maketitle
\end{document}


Supposing I want to decide where to break it and not leave this decision to the machine.

shadowtext does not understand the line breaking command \\ and so I have to write

\documentclass{paper}

\title{\shadowtext{Very long Title} \\ \shadowtext{is very long}}

\begin{document}
\maketitle
\end{document}


Is there a way to customise \title in order to just call \title{Very long title \\ is very long} and have a shadow text automatically?

shadowtext inserts the background as a picture, so you can use any regular stacking methods to put something one above the other. Below I use tabular:

\documentclass{paper}


Depending on your setup, there may be no need for using \title and \maketitle. In this case, you could use a \begin{center} \shadowtext{top} \\ \shadowtext{bottom} \end{center} setup.
