-\part{\texttt{pstricks} -- package}
-
-This version of the News was run with \verb|lualatex| \emph{without} using Ghostscript.
-The PDF file was created in a direkt way by Lua. If you want to try it, then look
-at \url{https://github.com/zauguin/luapstricks}.
-
-By default the dots are now taken from a Type1 version of the font file. For
-lualatex it uses the OpenType version.
-
-The dot part is now in an own file \texttt{pstricks-dots.tex}.
-
-
-

-\section{\texttt{pstricks.sty}}
-%--------------------------------------------------------------------------------------
-The optional argument \texttt{gsfonts} can be used to load only the symbol font from GhostScript.
-Otherwise the one from URW or the system is used, which is the default.

-\subsection{Presetting of \nxLkeyval{dimen} for circles}
-Some years ago the behaviour changed and \Lkeyset{dimen=middle} was preset for circles and ovals.
-It is now reverted to the old behaviour where all PSTricks objects have the presetting \Lkeyset{dimen=outer}.
-
-
-\subsection{Coordinates}
-By default the coordinates \verb|(10,10)| are used if the environment \Lenv{pspicture}
-is called without any given coordinates. This behaviour can be changed if you are running
-the document with \Lprog{lualatex}. Then you can use the optional argument \Lkeyword{calcframe}
-to allow the internal calculation of the box width and height. it needs two \Lprog{lualatex}
-runs to get the coordinates. The values are written into a file \verb|\jobname-<No>.psaux| and read
-in the next run.
-
-With the optional argument \Lkeyword{margin} it is possible to add white space to the calculated coordinates.
-The keyword must be set with the command \Lcs{psset} \emph{before} the environment \Lenv{pspicture}, otherwise it is too late.
-
-\begin{itemize}
-\item \verb|margin=5mm| will add 5mm on all sides of the box.
-\item \verb|margin={5mm,1cm}| will add 5mm on the left side and 1cm on the lower side of the box.
-\item \verb|margin={2mm,3,4,5pt}| will add 2mm on the left, 3\Lcs{psunit} at the bottom, 4\Lcs{psunit} on
-the right and 5pt on the top of the box. With the optional argument \Lkeyword{showframe} the calculated
-box coordinates can be visible. Additional white space is marked by a box with dashed lines.
-\end{itemize}
-
-Without a given unit all values are used with the current defined PSTricks unit. But remember
-that this will only work with \Lprog{lualatex}.
-
-The following example shows the same curve, but with different coordinates.
-
-\begin{LTXexample}[pos=t,width=\linewidth]

-\end{pspicture}X \hfill X%
-\begin{pspicture}[showgrid]
- \listplot[plotstyle=curve, showpoints]{\dataW} \rput(6,-0.5){default dataW}
-\end{pspicture}X \hfill X%
-\begin{pspicture}[showgrid]
- \listplot[plotstyle=curve, showpoints]{\dataV} \rput(6,-5.5){default dataV}
-\end{pspicture}X
-
-\vspace{1cm}
-X\begin{pspicture}[showgrid,margin=0.5]
- \listplot[plotstyle=curve, showpoints]{\dataU} \rput(1,5){margin=0.5}
-\end{pspicture}X \hfill X%
-\begin{pspicture}[showgrid,margin={0.5,1}]
- \listplot[plotstyle=curve, showpoints]{\dataW} \rput(6,4.5){margin={0.5 1}}
-\end{pspicture}X \hfill X%
-\begin{pspicture}[showgrid,margin={5mm,1,15mm,2}]
- \listplot[plotstyle=curve, showpoints]{\dataV} \rput(6,-0.5){margin={5mm,1,15mm,2}}
-\end{pspicture}X
-\end{LTXexample}
-
-Only PSTricks objects are taken into account for calculating the bounding box. All stuff
-which is placed on \TeX-level like any text with for example \Lcs{rput} cannot not be
-used for calculating the correct coordinates. With setting additional whitespace with
-the optional argument \Lkeyword{margin} the boxsize can be modified.

-\subsection{Colors}
-
-There are two new macros to get the color values:
-
-\begin{verbatim}
-\psgetRGBColorValues{<color macro>}
-\psgetCMYKColorValues{<color macro>}
-\end{verbatim}
-
-An Example:
-
-\begin{LTXexample}[width=5cm]
-\psset{linecolor=red!40}
-\psgetRGBColorValues{\pslinecolor}
-
-\colorlet{Blue}[cmyk]{blue}
-\psset{linecolor=Blue!40}
-\psgetCMYKColorValues{\pslinecolor}
-\end{LTXexample}
-
-
-\subsection{Arrows}
-
-
-There are new arrow types and a new optional argument \texttt{tipcolor}:
-
-
-\begin{LTXexample}[width=5cm]
-\begin{pspicture}[showgrid](4.2,3.25)
-\psline{-T>}(0,1)(4,1)
-\psline[arrowscale=2]{<T-T>}(0,2)(4,2)
-\psline[tipcolor=red,arrowscale=2]{<T-}(0,3)(4,3)
-\end{pspicture}
-\end{LTXexample}
-
-
-
-\LPack{pstricks} defines the following "`arrows"':
-
- \def\myline#1{\psline[linecolor=red,linewidth=0.5pt,arrowscale=1.5]{#1}(0,1ex)(1.3,1ex)}%
- \def\mylineA#1{\psline[linecolor=red,linewidth=0.5pt,arrowscale=4.5]{#1}(0,1ex)(2,1ex)}%
- \psset{arrowscale=1.5}

-With version 3.04 all arrow specific base code is moved to the file \LPack{pstricks-arrows}, which
-is not of interest for the default user..
-
-\subsection{Symbolfont}
-
-
-Use by default the URW or system symbol font for \Lcs{psdot}. This can be changes by using
-the optional argument \texttt{gsfonts}:
-
-\begin{verbatim}
-\usepackage[gsfonts]{pstricks}
-\end{verbatim}
-
-\TeX-users have to define the switch and
-
-\begin{verbatim}
-\newif\ifpstGSfonts
-\pstGSfontsfalse % or true for using GS font
-
-\input pstricks
-...
-\end{verbatim}
-
-
-\subsection{Fillstyle \texttt{penrose}}
-
-There was a bug if this fillstyle was used together with a line sequence.

-Currently one has to use package \LPack{auto-pst-pdf-lua} if a document with
-\PSTricks-code should be run \emph{directly} with \LuaLaTeX, without using
-GhostScript. This version has experimental basic support for the lua package
