[texhax] Using "\pause" in Powerdot

[Hubert Lam]

This is somewhat pstricks related, but mostly Powerdot related.

I would like to show working line by line in a gather*/aligned or align*
environment, using the "\pause" command" like this:

\begin{slide}[toc=,bm=]{Expand}
Expand the following (not-so-easy) binomial expressions:
\begin{itemize}
\item<1-> $(a + b)^4$
        \begin{align*} \pause
        (a + b)^4   &= (a + b)(a + b)^3  \\ \pause
                    &= (a + b)(1a^3 + 3a^2 b + 3ab^2 + 1b^3)  \\ \pause
                    &= 1a^4 + 4a^3 b + 6a^2 b^2 + 4ab^3 + 1b^4
        \end{align*}
\end{itemize}
\end{slide}


In the manual the authors of powerdot manage to pause a lstlisting.
However there are no examples for other math environments.

Is this possible at all?

The pstricks-related part is that if I were to show a part of a diagram
being drawn, it obviously wouldn't be possible unless I progressively
altered the diagrams slide by slide, correct?

Many thanks

Hubert
