\section{Opacity}
The keyword \Lkeyword{strokeopacity} is now also valid for \Lcs{psdot}, \Lcs{psdots},
and the \Lkeyword{linestyle}/\Lkeyword{plotstyle}=\Lkeyval{dots}.
\subsection{PostScript notation for numbers}
Optional arguments which expects a real number can now have a preceeding ! character for
a PostScript notation which is directly passed to PostScript. The user has take care that
such a number isn't use before in another \TeX\ macro. In such a case it gives an error.
\begin{LTXexample}[width=5cm]
\pstVerb{ 1234321 srand }
\begin{pspicture}[showgrid](-2,-2)(2,2)
\psframe*[linecolor=blue,opacity=!Rand](2,2)
\psframe*[linecolor=red,opacity=!Rand](-1,-1)(1,1)
\psframe*[linecolor=green,opacity=!Rand](-2,-2)(0,0)
\end{pspicture}
\end{LTXexample}
\subsection{Fillstyle \texttt{eofill}}
It is an experimental fillstyle. PostScript knows only the \Lkeyval{eofill} and the other way round
needs some tricky internal commands and may not work in all cases.
\begin{LTXexample}[pos=t]
\begin{pspicture}[linewidth=2pt](12,4)
\pscustom[linestyle=none,fillstyle=eofill,fillcolor=blue!40]{%
\psellipse(4,2)(2,2)\psellipse(2,2)(2,2)}
\psellipse[linecolor=red](4,2)(2,2)
\psellipse[linecolor=green](2,2)(2,2)
%
\pscustom[linestyle=none,fillstyle=oefill,fillcolor=blue!40]{%
\psellipse(10,2)(2,2)\psellipse(8,2)(2,2)}
\psellipse[linecolor=red](10,2)(2,2)
\psellipse[linecolor=green](8,2)(2,2)
\end{pspicture}
\end{LTXexample}
\subsection{New macro \nxLcs{psRing}}
\begin{BDef}
\LcsStar{psRing}\OptArgs\Largr{\CAny}\OptArg{start,end}\Largb{Inner Radius}\Largb{Outer Radius}
\end{BDef}
\begin{LTXexample}[width=5cm]
\begin{pspicture}[showgrid](4,4)
\psRing(2,2){0.3}{0.8}
\psRing*[opacity=0.5](2,2){1}{2}
\psdot(2,2)
\end{pspicture}
\end{LTXexample}
\begin{LTXexample}[width=5cm]
\begin{pspicture}[showgrid](4,4)
\psRing[linecolor=red](2,2)[30,60]{1}{2}
\psRing[opacity=0.5,fillstyle=solid,
fillcolor=red](2,2)[60,30]{1}{2}
\psdot(2,2)
