+\section{Calendar: Weeknumbers and more conditionals}
+\begin{package}{calendar-ext}
+  This package adds week numbers and more conditionals to the PGF package |pgfcalendar|.
+  (Despite the code example above, this package is not set up to work with Con\TeX t.)
+\end{package}
+
+%This package extends the |pgfcalendar| package.
+
+\begin{multicols}{2}
+
+\subsection{Extensions}
+
+The following tests are added.
+\begin{itemize}
+\itemcalendaroption{Jan} This test is passed by all dates that are in the month of January.
+\itemcalendaroption{Feb} as above.
+\itemcalendaroption{Mar} as above.
+\itemcalendaroption{Apr} as above.
+\itemcalendaroption{May} as above.
+\itemcalendaroption{Jun} as above.
+\itemcalendaroption{Jul} as above.
+\itemcalendaroption{Aug} as above.
+\itemcalendaroption{Sep} as above.
+\itemcalendaroption{Oct} as above.
+\itemcalendaroption{Nov} as above.
+\itemcalendaroption{Dec} as above.
+\itemcalendaroption{leap year}\opt{|=|\meta{year}}
+    This test checks whether the given year is a leap year. If
+    \meta{year} is omitted, it checks the year of the current date.
+\itemcalendaroption{and}|=|\marg{tests}
+    This test passes when all \meta{tests} pass.
+\itemcalendaroption{not}|=|\marg{tests}
+    This test passes when \meta{tests} do not pass.
+\itemcalendaroption{yesterday}|=|\marg{tests}
+    This test passes when the previous day passes \meta{tests}.
+\itemcalendaroption{week}|=|\meta{num}
+    This test passes when the current week of the year equals \marg{num}.
+\end{itemize}
+
+The shorthands for |d-| and |m-| are slightly changed so that they are
+expandable. This makes it possible to use these shorthands inside of PGFmath.
+The shorthands for the week (see section~\ref{calendar:weeknumbering})
+are added. These are
+\begin{itemize}
+\item |n-| (shortest numerical representation),
+\item |n=| (shortest but added horizontal space) and
+\item |n0| (leading zero when below 10).
+\end{itemize}
+
+\subsection{Week numbering (ISO~8601)}
+\label{calendar:weeknumbering}
+\begin{command}{\pgfcalendarjulianyeartoweek\marg{Julian day}\marg{year}\marg{week counter}}
+  This command calculates the week for the \meta{Julian day} of \meta{year}.
+  The \meta{week counter} must be a \TeX\space counter.
+
+  The calculation follows the rule of ISO~8601 where the first week has that
+  year's first Thursday in it.
+\end{command}
+
+Inside of |\pgfcalendar|\indexCommandO\pgfcalendar the command |\pgfcalendarcurrentweek| will be available.
+\begin{command}{\pgfcalendarcurrentweek}
+  This command returns the current week number (always two digits -- use shorthand |n.|
+  to strip the leading zero).
+\end{command}
+
+Inside of |\ifdate|\indexCommandO\ifdate the command |\pgfcalendarifdateweek| will be available.
+\begin{command}{\pgfcalendarifdateweek}
+  This command returns the week number (always two digits).
+\end{command}
+\end{multicols}

+\part{Introduction}
+\begin{multicols}{2}
+\section{Usage}
+This package is called |tikz-ext|, however, one can't load it via |\usepackage|.
+Instead, this package consists of multiple PGF and \tikzname\space libraries
+which are loaded by either |\usepgflibrary| or |\usetikzlibrary|.
+
+\section{Why do we need it?}
+Since I have been answering questions on \hyperlink{https://tex.stackexchange.com}{TeX.sx}
+I've noticed that some questions come up again and again,
+every time with a slightly different approach on how to solve them.
+
+I don't like reinventing the wheel which is why I've gathered the code of my answers in this package.
+
+And, yes, I am using them myself, too.
+
+\section{Should these libraries be part of \tikzname?}
+I guess.

+\section{Calendar}
+\begin{tikzlibrary}{ext.calendar-plus}
+  This library extends the \tikzname\space library |calendar|\indexLibraryO{calendar}.
+\end{tikzlibrary}
+
+\begin{multicols}{2}
+
+\subsection{Value-keys and nestable \texttt{if} key}
+
+The values of following keys are originally stored in some macros that are not
+accessible by the user. These are now simple value-keys.
+The |@|-protected macros are still available, of course.
+
+\begin{key}{/tikz/day xshift (initially 3ex)}
+\end{key}
+\begin{key}{/tikz/day yshift (initially 3.5ex)}
+\end{key}
+\begin{key}{/tikz/month xshift (initially 9ex)}
+\end{key}
+\begin{key}{/tikz/month yshift (initially 9ex)}
+\end{key}
+
+It is now also possible to nest |/tikz/if| occurrences.
+\begin{key}{/tikz/if=|(|\meta{conditions}|)|\meta{code or options}\opt{|else|\meta{else code or options}}}
+\end{key}
+
+\subsection{Week numbering (ISO~8601)}
+
+The actual week number algorithm is implemented by the |pgfcalendar-ext| package/module in section~\ref{calendar:weeknumbering}.
+\begin{key}{/tikz/week code=\meta{code}}
+  Works like |/tikz/day code| or |/tikz/month code|, only for weeks.\indexKeyO{day code}\indexKeyO{month code}
+\end{key}
+
+\begin{key}{/tikz/week text=\meta{text}}
+  Works like |/tikz/day text| or |/tikz/month text|, only for weeks.\indexKeyO{day text}\indexKeyO{month text}
+\end{key}
+
+\begin{stylekey}{/tikz/every week}
+  Works like |/tikz/every day| or |/tikz/every month|, only for weeks.\indexKeyO{every day}\indexKeyO{every month}
+\end{stylekey}
+
+\begin{stylekey}{/tikz/week label left}
+    Places the week label to the left of the first day of the month. (For
+    |week list| and |month list| where a week does not start on a Monday, the
+    position is chosen ``as if'' the week had started on a Monday --  which is
+    usually exactly what you want.)
+    %
+\begin{codeexample}[preamble={\usetikzlibrary{ext.calendar-plus}}]
+\tikz
+  \calendar [week list, month label above centered,
+             dates=2022-07-01 to 2022-07-31,
+             week label left,
+             every week/.append style={gray!50!black,font=\sffamily}];

+\section{And a little bit more}
+\begin{tikzlibrary}{ext.misc}
+  This library adds miscellaneous utilities to PGFmath, PGF or \tikzname.
+\end{tikzlibrary}
+
+\subsection{PGFmath}
+
+\begin{multicols}{2}
+\pgfkeys{/codeexample/every codeexample/.append style={width=3cm}}
+\subsubsection{Postfix operator \texttt{R}}
+
+Similar to |\segments[<num>]| in PSTricks, the postfix operator |R| allows the user
+to use an arbitrary number of segments of a circle to be used instead of an angle.
+
+\begin{key}{/tikz/full arc=\meta{num} (default |{}|)}
+  The number \meta{num} of segments will be set up.
+  Using |full arc| with an empty value disables the segmentation and |1R| equals $1^\circ$.
+  
+  The given value \meta{num} is evaluated when the key is used and doesn't change when
+  \meta{num} contains variables that change.
+\end{key}
+The |R| operator can then be used.
+\begin{math-operator}{R}{postfix}{fullarc}
+  Multiplies \mvar{x} with $\frac{360}{\meta{num}}$.
+\end{math-operator}
+
+\subsubsection{Functions}
+
+\begin{math-function}{strrepeat("\mvar{Text}", \mvar{x})}
+\mathcommand
+  Returns a string with \mvar{Text} repeated \mvar{x} times.
+
+\begin{codeexample}[]
+\pgfmathparse{strrepeat("foo", 5)}
+\pgfmathresult
+\end{codeexample}
+\end{math-function}
+
+\begin{math-function}{isInString("\mvar{String}", "\mvar{Text}")}
+\mathcommand
+  Returns |1| (true) if \mvar{Text} contains \mvar{String},
+  otherwise |0| (false).
+
+\begin{codeexample}[]
+\pgfmathparse{isInString("foo", "bar")}
+\pgfmathresult \ and\ 
+\pgfmathparse{isInString("foo", "foobar")}
+\pgfmathresult
+\end{codeexample}
+\end{math-function}
+
+\begin{math-function}{strcat("\mvar{Text A}", "\mvar{Text B}", …)}
+\mathcommand
+  Returns the concatenation of all given parameters.
+
+\begin{codeexample}[]
+\pgfmathparse{strcat("blue!", int(7*3), "!green")}
+\pgfmathresult
+\end{codeexample}
+\end{math-function}
+
+
+\begin{math-function}{isEmpty("\mvar{Text}")}
+\mathcommand
+  Returns |1| (true) if \mvar{Text} is empty, otherwise |0| (false).
+  %
+\begin{codeexample}[]
+\pgfmathparse{isEmpty("foo")} \pgfmathresult\ and\ 
+\pgfmathparse{isEmpty("")}    \pgfmathresult\ and\ 
+\def\emptyText{}
+\pgfmathparse{isEmpty("\emptyText")} \pgfmathresult
+\end{codeexample}
+\end{math-function}
+
+\begin{math-function}{atanXY(\mvar{x},\mvar{y})}
+\mathcommand
+  Arctangent of $\mvar y\div \mvar x$ in degrees. This also takes into account the quadrant.
+  This is just a argument-swapped version of |atan2|\indexMathFunctionO{atan2} which makes it easier to use
+  the |\p| commands of the |calc|\indexLibraryO{calc} library.
+  %
+\begin{codeexample}[]
+\pgfmathparse{atanXY(3,4)} \pgfmathresult
+\end{codeexample}
+\end{math-function}
+\begin{math-function}{atanYX(\mvar{y},\mvar{x})}
+\mathcommand
+   Arctangent of $y\div x$ in degrees. This also takes into account the quadrant.
+\begin{codeexample}[]
+\pgfmathparse{atanYX(4,3)} \pgfmathresult
+\end{codeexample}
+\end{math-function}
+
+\subsubsection{Functions: using coordinates}
+The following functions can only be used with PGF and/or \tikzname.
+Since the arguments are usually plain text (and not numbers) one has to wrap
+them in |"|.
+\begin{math-function}{anglebetween("\mvar{p1}", "\mvar{p2}")}\mathcommand
+  Return the angle between the centers of the nodes \mvar{p1} and \mvar{p2}.
+\end{math-function}
+\begin{math-function}{qanglebetween("\mvar{p}")}\mathcommand
+  Return the angle between the origin and the center of the node \mvar{p}.
+\end{math-function}
+\begin{math-function}{distancebetween("\mvar{p1}", "\mvar{p2}")}\mathcommand
+  Return the distance (in pt) between the centers of the nodes \mvar{p1} and \mvar{p2}.
+\end{math-function}
+\begin{math-function}{qdistancebetween("\mvar{p}")}\mathcommand
+  Return the distance (in pt) between the origin and the center of the node \mvar{p}.
+\end{math-function}
+
+\end{multicols}
+
+\begin{codeexample}[width=6cm,preamble=\usetikzlibrary{calc,ext.misc,through}]
+\begin{tikzpicture}
+\path (0,0) coordinate (A) + (0:4) coordinate (B) +(75:4) coordinate (C);
+\draw (A) -- (B) -- (C) -- cycle;
+\foreach \cnt in {1,...,4}{
+  \pgfmathsetmacro\triA{distancebetween("B","C")}
+  \pgfmathsetmacro\triB{distancebetween("C","A")}
+  \pgfmathsetmacro\triC{distancebetween("A","B")}
+  \path (barycentric cs:A=\triA,B=\triB,C=\triC) coordinate (M)
+       node [draw, circle through=($(A)!(M)!(C)$)] (M) {};
+  \draw ($(C)-(A)$) coordinate (vecB)
+      (M.75-90) coordinate (@)
+      (intersection of @--[shift=(vecB)]@ and B--C) coordinate (C) -- 
+      (intersection of @--[shift=(vecB)]@ and B--A) coordinate (A);}
+\end{tikzpicture}
+\end{codeexample}
+\subsection{PGFkeys}
+
+\begin{multicols}{2}
+
+\subsubsection{Conditionals}
+
+\begin{key}{/utils/if=\meta{cond}\meta{true}\opt{\meta{false}}}
+  This key checks the conditional \meta{cond} and applies the styles \meta{true}
+  if \meta{cond} is true, otherwise \meta{false}.
+  \meta{cond} can be anything that PGFmath understands.
+  
+  As a side effect on how PGFkeys parses argument, the \meta{false} argument is
+  actually optional.
+\end{key}
+
+The following keys use \TeX' macros |\if|, |\ifx|, |\ifnum| and |\ifdim| for faster
+executions.
+
+\begin{key}{/utils/TeX/if=\meta{token A}\meta{token B}\meta{true}\opt{\meta{false}}}
+  This key checks via |\if| if \meta{token A} matches \meta{token B}
+  and applies the styles \meta{true} if it does, otherwise \meta{false}.
+  
+  As a side effect on how PGFkeys parses argument, the \meta{false} argument is
+  actually optional.
+\end{key}
+
+\begin{key}{/utils/TeX/ifx=\meta{token A}\meta{token B}\meta{true}\opt{\meta{false}}}
+  As above.
+\end{key}
+
+\begin{key}{/utils/TeX/ifnum=\meta{num cond}\meta{true}\\opt{\meta{false}}}
+  This key checks |\ifnum|\meta{num cond}
+  and applies the styles \meta{true} if true, otherwise \meta{false}.
+  A delimiting |\relax| will be inserted after \meta{num cond}.
+  
+  As a side effect on how PGFkeys parses argument, the \meta{false} argument is
+  actually optional.
+\end{key}
+
+\begin{key}{/utils/TeX/ifdim=\meta{dim cond}\meta{true}\opt{\meta{false}}}
+  As above.
+\end{key}
+
+\begin{key}{/utils/TeX/ifempty=\meta{Text}\meta{true}\opt{\meta{false}}}
+  This checks whether \meta{Text} is empty and applies styles \meta{true} if true,
+  otherwise \meta{false}.
+\end{key}
+
+
+\subsubsection{Handlers}
+
+While already a lot of values given to keys are evaluated by PGFmath at some point,
+not all of them are.
+
+\begin{handler}{{.pgfmath}|=|\meta{eval}}
+  This handler evaluates \meta{eval} before it is handed to the key.
+\end{handler}
+
+\begin{handler}{{.pgfmath int}|=|\meta{eval}}
+  As above but truncates the result.
+\end{handler}
+
+\begin{handler}{{.pgfmath strcat}|=|\meta{eval}}
+  As above but uses the |strcat| function.
+  
+  In the example below, one could have used the |/pgf/foreach/evaluate| key from |\foreach|.
+\begin{codeexample}[width=3.7cm,preamble=\usetikzlibrary{misc}]
+\tikz\foreach \i in {0,10,...,100}
+\draw[
+  line width=+.2cm,
+  color/.pgfmath strcat={"red!",sqrt(\i)*10,"!blue"}
+]
+  (0,\i/50) -- +(right:3);
+\end{codeexample}
+\end{handler}
+
+\begin{handler}{{.List}|=|\meta{\meta{e1}, \meta{e2}, \dots, \meta{en}}}
+  This handler evaluates the given list with |\foreach| and concatenates the element and
+  the result is then given to the used key.
+\end{handler}
+\end{multicols}
+\begin{codeexample}[width=6cm,preamble=\usetikzlibrary{fit,ext.misc}]
+\begin{tikzpicture}[nodes={draw, dashed, inner sep=+10pt}]
+  \foreach \point [count=\cnt] in {(0,0), (0,2), (2,0), (2,2), (3,3), (-1,-1)}
+    \fill \point circle[radius=.1] coordinate (point-\cnt);
+  \node[gray, fit/.List={(point-1),(point-...),(point-4)}] {}; 
+  \node[red,  fit/.List={(point-1),(point-...),(point-5)}] {}; 
+  \node[blue, fit/.List={(point-1),(point-...),(point-6)}] {};
+\end{tikzpicture}
+\end{codeexample}
+
+\subsection{PGFfor}
+
+Instead of |\foreach \var in {start, start + delta, ..., end}| one can use
+|\foreach \var[use int=start to end step delta]|.
+
+\begin{key}{/pgf/foreach/use int=\meta{start}|to|\meta{end}\opt{|step|\meta{delta}}}
+The values \meta{start}, \meta{end} and \meta{delta} are evaluates by PGFmath at initialization.
+The part |step |\meta{delta} is optional (\meta{delta} = 1).
+\end{key}
+
+\begin{key}{/pgf/foreach/use float=\meta{start}|to|\meta{end}\opt{|step|\meta{delta}}}
+Same as above, however the results are not truncated.
+\end{key}

+\section{Node Families}
+\begin{tikzlibrary}{ext.node-families}
+  With this library the user can instruct multiple nodes to have the same
+  width, height, text width, text height or text width.
+  This uses the hook \referenceKeyandIndexO{execute at end picture} to write the nodes'
+  measurements to the \filetype{aux} file.
+  
+  Unfortunately, this does not work with the |external| library.\indexLibraryO{external}%
+  \footnote{Not only would the \texttt{external} library not notice the change of the value between compilations runs,
+    it also changes the way \texttt{\textbackslash pgfutil@writeout} works which suddenly writes to the \textsc{log} file instead.}
+\end{tikzlibrary}
+
+This library introduces two new shapes called |Circle| and |Rectangle|
+that are basically copies of the original shapes |circle|\indexShapeO{circle} and |rectangle|\indexShapeO{rectangle}.
+However, their dimension will be set to the same maximum |minimum width| and |minimum height|
+when one of the following \meta{name}s are declared.
+\begin{key}{/tikz/node family/width=\meta{name} (initially |\{\}|)}
+Nodes with the same \meta{name} will have the same \referenceKeyandIndexO[/pgf/]{minimum width}.
+An empty \meta{name} disables the evaluation by the library.
+\begin{codeexample}[preamble=\usetikzlibrary{positioning,ext.node-families},/tikz/node distance=.5cm]
+\tikzexternaldisable % ext.node-families does not work with active externalization
+\begin{tikzpicture}[nodes={Rectangle, draw, node family/width=manual}]
+\node (a) {Foo};
+\node[below=of a] (b) {Foobar};
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+\begin{key}{/tikz/node family/height=\meta{name} (initially |\{\}|)}
+Nodes with the same \meta{name} will have the same \referenceKeyandIndexO[/pgf/]{minimum height}.
+An empty \meta{name} disables the evaluation by the library.
+\end{key}
+\begin{key}{/tikz/node family/size=\meta{name}}
+Sets both |height| and |width|.
+\end{key}
+
+While |node family/width| and |node family/height| only work for the new shapes |Circle| and |Rectangle|,
+the following keys~-- when setup, see below~-- work with every shape with one single node part.
+Initially though, only |circle|, |rectangle|, |Circle| and |Rectangle| are set up that way.
+\begin{key}{/tikz/node family/text height=\meta{name} (initially |\{\}|)}
+Nodes with the same \meta{name} will have the same text height.
+An empty \meta{name} disables the evaluation by the library.
+\end{key}
+
+\begin{key}{/tikz/node family/text depth=\meta{name} (initially |\{\}|)}
+Nodes with the same \meta{name}  will have the same text depth.
+An empty \meta{name} disables the evaluation by the library.
+\end{key}
+
+\begin{key}{/tikz/node family/text width=\meta{name} (initially |\{\}|)}
+Nodes with the same \meta{name} will have the same text width.
+An empty \meta{name} disables the evaluation by the library.
+\end{key}
+
+\begin{key}{/tikz/node family/text=\meta{name}}
+Sets |text height|, |text depth| and |text width|.
+\end{key}
+
+Since the width of the node's content's box is setup much earlier,
+the previous key only extends the width of that box which would make the text
+seem as if it where aligned to the left.
+With |text width family align| this can changed.
+\begin{key}{/tikz/node family/text width align=\meta{alignment}(initially |center|)}
+\meta{alignment} is one of |left|, |center| or |right|.
+
+\begin{codeexample}[preamble=\usetikzlibrary{positioning,ext.node-families},/tikz/node distance=.5cm]
+\tikzexternaldisable % ext.node-families does not work with active externalization

+\section{Arc \emph{to} a point}
+\label{library:paths.arcto}
+
+\begin{tikzlibrary}{ext.paths.arcto}
+  This library adds the new path operation |arc to| that specifies an arc \emph{to} a point~--
+  without the user having to specify any angles.
+\end{tikzlibrary}
+
+\begin{codeexample}[width=.5\linewidth,preamble=\usetikzlibrary{ext.paths.arcto}]
+\begin{tikzpicture}[ultra thick,dot/.style={label={#1}}]
+\coordinate[dot=below left:$a$] (a) at (0,0);
+\coordinate[dot=above right:$b$] (b) at (2,3);
+\begin{scope}[
+  radius=3,
+  nodes={
+    shape=circle,
+    fill=white,
+    fill opacity=.9,
+    text opacity=1,
+    inner sep=+0pt,
+    sloped,
+    allow upside down
+  }]
+\draw[blue]    (a) arc to[] 
+  node[near start] {.25} node {.5} node[near end] {.75} (b);
+\draw[red]     (a) arc to[clockwise]
+  node[near start] {.25} node {.5} node[near end] {.75} (b);
+\draw[blue!50] (a) arc to[large]
+  node[near start] {.25} node {.5} node[near end] {.75} (b);
+\draw[red!50]  (a) arc to[large, clockwise]
+  node[near start] {.25} node {.5} node[near end] {.75} (b);
+\end{scope}
+
+\fill[radius=2pt] (a) circle[] (b) circle[];
+\end{tikzpicture}
+\end{codeexample}
+
+\begin{pathoperation}{arc to}{\opt{\oarg{options}}\meta{coordinate or cycle}}
+When this operation is used, the path gets extended by an arc that goes through
+the current point and \meta{coordinate}.
+
+For two points there exist two circles or four arcs that go through or connect
+these two points. Which one of these is constructed is determined by the following
+options that can be used inside of \meta{options}.
+
+\begin{stylekey}{/tikz/arc to/clockwise}
+  This constructs an arc that goes clockwise.
+\end{stylekey}
+
+\begin{stylekey}{/tikz/arc to/counter clockwise}
+  This constructs an arc that goes counter clockwise.
+  
+  This is the default.
+\end{stylekey}
+
+\begin{stylekey}{/tikz/arc to/large}
+  This constructs an arc whose angle is larger than $180^\circ$.
+\end{stylekey}
+
+\begin{stylekey}{/tikz/arc to/small}
+  This constructs an arc whose angle is smaller than $180^\circ$.
+\end{stylekey}
+
+\begin{key}{/tikz/arc to/rotate=\meta{degree}}
+  Rotates the arc by \meta{degree}.
+  This is only noticeable when |x radius| and |y radius| are different.
+\end{key}
+
+\begin{key}{/tikz/arc to/x radius=\meta{value}}
+  This forwards the \meta{value} to \referenceKeyandIndexO{x radius}.
+  Its \meta{value} is used for the radius of the arc.
+\end{key}
+
+\begin{key}{/tikz/arc to/y radius=\meta{value}}
+  This forwards the \meta{value} to \referenceKeyandIndexO{y radius}.
+  Its \meta{value} is used for the radius of the arc.
+\end{key}
+
+\begin{key}{/tikz/arc to/radius=\meta{value}}
+  This forwards the \meta{value} to both |/tikz/x radius| and |/tikz/y radius|.
+  Its \meta{value} is used for radius of the arc.
+\end{key}
+
+\begin{stylekey}{/tikz/every arc to}
+  After |/tikz/every arc| this will also be applied before any \meta{options} are set.
+\end{stylekey}
+
+It should be noted that this uses |\pgfpatharcto| for which the \tikzname\space manual warns:\indexCommandO\pgfpatharcto
+\begin{quote}\itshape
+    The internal computations necessary for this command are numerically very unstable.
+    In particular, the arc will not always really end at the \meta{target coordinate},
+    but may be off by up to several points.
+    A more precise positioning is currently infeasible due to \TeX's numerical weaknesses.
+    The only case it works quite nicely is when the resulting angle is a multiple of $90^\circ$. 
+\end{quote}
+
+The |arc to| path operation will also work only in the |canvas| coordinate system.
+The lengths of the vectors $(1, 0)$ and $(0, 1)$ will be used for the calculation of the radii
+but no further consideration is done.

+\begin{tikzlibrary}{ext.paths.ortho}
+  This library adds new path specifications \verb!|-|!, \verb!-|-! as well as

+\end{tikzlibrary}
+
+\subsection{Zig-Zag}
+Similar to the path operations \verb!|-! and \verb!-|! this library adds\indexPathOperationO{\protect\pgfmanualbar-}\indexPathOperationO{-\protect\pgfmanualbar}
+the path operations \verb!|-|! and \verb!-|-!.

+\end{pathoperation}
+}
+\begin{key}{/tikz/hvvh/ratio=\meta{ratio} (initially 0.5)}
+  This sets the ratio for the middle part of the Zig-Zag connection.
+  
+  For values $\meta{ratio} < 0$ and $\meta{ratio} > 1$ the Zig-Zag lines will
+  look more like Zig-Zig lines.
+\begin{codeexample}[preamble=\usetikzlibrary{paths.ortho}]
+\begin{tikzpicture}[very thick, rounded corners]

+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+%TODO: hvvh/distance needs fixing, maybe?
+\begin{key}{/tikz/hvvh/distance=\meta{distance}}
+  This sets the distance between the start point
+  and the middle part of the Zig-Zag connection.
+  
+  For values $\meta{distance} < 0$ the distance will be used for the target coordinate.
+\begin{codeexample}[width=8cm,preamble=\usetikzlibrary{ext.paths.ortho}]
+\begin{tikzpicture}[very thick,-latex]
+\draw[help lines,-] (-.25, -.25) grid (5.25, 3.25);

+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+\begin{key}{/tikz/hvvh/from center=\opt{\meta{true or false}} (default true)}
+  When nodes get connected the placement of the middle part of the Zig-Zag
+  and the Zig-Zig (see below) connections will be calculated from the border
+  of these nodes.
+  The middle part of the connections can be calculated from the nodes' center
+  if this key is set to |true|.
+\end{key}
+
+New timers are setup for both the Zig-Zag and the Zig-Zig connections,
+these can be configured through the following keys.
+\begin{codeexample}[width=8cm,preamble=\usetikzlibrary{paths.ortho}]
+\tikz \draw (0,0) -|- (2,3) 
+  foreach \p in {0.0, 0.25, 0.5, 0.75, 1.0}{
+    node [pos=\p] {\p}};
+\end{codeexample}
+\begin{key}{/tikz/hvvh/spacing=\meta{number} (initially 4)}
+  Unless $\meta{number} = 0$ is set
+  \begin{itemize}
+  \item |pos = 0| will be at the start,\indexKeyO{pos}
+  \item |pos = 1| will be at the end,
+  \item |pos = |$\frac{1}{\meta{number}}$ will be at the first kink,
+  \item |pos = |$\frac{\meta{number}-1}{\meta{number}}$ will be at the second kink and
+  \item |pos = .5| will be in the middle of the middle part of the connection.
+  \end{itemize}
+  
+  If $\meta{number} = 0$ then
+  \begin{itemize}
+  \item |pos = -1| will be at the start,
+  \item |pos = 2| will be at the end,
+  \item |pos = 0| will be at the first kink,
+  \item |pos = 1| will be at the second kink and
+  \item |pos = .5| will still be in the middle of the middle part of the connection.
+  \end{itemize}
+\end{key}
+\begin{key}{/tikz/hvvh/middle 0 to 1}
+  This is an alias for |spacing = 0|.
+\end{key}
+
+\subsection{Zig-Zig}
+\begin{pathoperation}{r-ud}{\opt{\oarg{options}}\meta{coordinate or cycle}}
+  This operation means ``first up, then horizontal and then down''.
+  \begin{key}{/tikz/udlr/ud distance=\meta{length} (initially .5cm)}
+    This sets the distance between the start and the horizontal line to \meta{length}.
+  \end{key}
+\end{pathoperation}
+\begin{pathoperation}{r-du}{\opt{\oarg{options}}\meta{coordinate or cycle}}
+  This operation means ``first down, then horizontal and then up''.
+  \begin{key}{/tikz/udlr/du distance=\meta{length} (initially .5cm)}
+    This sets the distance between the start and the horizontal line to \meta{length}.
+  \end{key}
+\end{pathoperation}
+\begin{pathoperation}{r-lr}{\opt{\oarg{options}}\meta{coordinate or cycle}}
+  This operation means ``left down, then vertical and then right''.
+  \begin{key}{/tikz/udlr/lr distance=\meta{length} (initially .5cm)}
+    This sets the distance between the start and the vertical line to \meta{length}.
+  \end{key}
+\end{pathoperation}
+\begin{pathoperation}{r-rl}{\opt{\oarg{options}}\meta{coordinate or cycle}}
+  This operation means ``first right, then vertical and then down''.
+  \begin{key}{/tikz/udlr/rl distance=\meta{length} (initially .5cm)}
+    This sets the distance between the start and the vertical line to \meta{length}.
+  \end{key}
+\end{pathoperation}
+
+All distances can be set with on key.
+\begin{key}{/tikz/udlr/distance=\meta{length}}
+  Sets all distances in the |/tikz/udlr| namespace.
+\end{key}
+
+\begin{key}{/tikz/udlr/from center=\opt{\meta{true or false}} (initially false, default true)}
+  This is an alias for |/tikz/hvvh/from center|.
+\end{key}
+
+\subsection{Even more Horizontal and Vertical Lines}
+
+The following keys can be used to access vertical and horizontal line path operations.
+\begin{stylekey}{/tikz/horizontal vertical}
+  This installs  \verb!to path = -| (\tikztotarget) \tikztonodes! that can be used with\indexKeyO{to path}
+  the path operations |to| or |edge|.
+\end{stylekey}
+\begin{stylekey}{/tikz/vertical horizontal}
+  This installs \verb!to path = |- (\tikztotarget) \tikztonodes! that can be used with
+  the path operations |to| or |edge|.
+\end{stylekey}
+\begin{stylekey}{/tikz/horizontal vertical horizontal}
+  This installs  \verb!to path = -|- (\tikztotarget) \tikztonodes! that can be used with
+  the path operations |to| or |edge|.
+\end{stylekey}
+\begin{stylekey}{/tikz/vertical horizontal vertical}
+  This installs  \verb!to path = |-| (\tikztotarget) \tikztonodes! that can be used with
+  the path operations |to| or |edge|.
+\end{stylekey}
+
+When connecting rectangular nodes, these keys could be useful as well.
+They all need to be given to a |to| or |edge| path operation.
+\begin{stylekey}{/tikz/only vertical second=\opt{\meta{length}} (default 0pt)}
+This draws a vertical line from the start point to the target point so that
+it connects to the target point in the center (or at its border in case it is a node).
+
+The optional \meta{length} can be used to shift the line orthogonally to its direction.
+\end{stylekey}
+\begin{stylekey}{/tikz/only horizontal second=\opt{\meta{length}} (default 0pt)}
+This draws a horizontal line from the start point to the target point so that
+it connects to the target point in the center (or at its border in case it is a node).
+
+The optional \meta{length} can be used to shift the line orthogonally to its direction.
+\end{stylekey}
+\begin{stylekey}{/tikz/only vertical first=\opt{\meta{length}} (default 0pt)}
+This draws a vertical line from the start point to the target point so that

+
+The optional \meta{length} can be used to shift the line orthogonally to its direction.
+\end{stylekey}

+\section{Extending the Path Timers}
+\label{library:timer}
+
+\begin{tikzlibrary}{ext.paths.timer}
+  This library adds timers to the path specifications |rectangle|, |parabola|, |sin| and |cos|.
+\end{tikzlibrary}
+
+In \tikzname, the path specification |rectangle|, |parabola|, |sin| and |cos| do not provide
+their own timer, i.\,e. a node placing algorithm that is dependent on the actual path.
+For |rectangle| the timer of the straight line between the rectangle's corners is used, for
+the other paths, nodes, coordinates, pics, etc. are placed on the last coordinate.
+
+This library allows this.
+
+\subsection{Rectangle}
+\indexPathOperationO{rectangle}
+
+For the |rectangle| path operator, the timer starts with |pos = 0| (= |at start|) from\indexKeyO{pos}
+the starting coordinate in a counter-clockwise direction along the rectangle.
+The corners will be at positions 0.0, 0.25, 0.5, 0.75 and 1.0.
+
+\begin{codeexample}[width=10cm,preamble=\usetikzlibrary{ext.paths.timer}]
+\begin{tikzpicture}[scale=2, every pin edge/.style={latex-, gray}]
+\coordinate [label=above right:Target] (A) at (0,0);
+\coordinate [label=below left:Start]   (B) at (1,2);
+\draw[->, help lines] ([shift=(50:.3 and .75)] .5,1)
+  arc[start angle=50, delta angle=340, x radius=.3, y radius=.75];
+\draw (B) rectangle (A)
+  foreach \pos/\ang in {at start/60, very near start/90, near start/180, pos=.375/180,
+                        midway/180, pos=.625/270, near end/0, very near end/0, at end/0}{
+    node[pin=\ang:\pos, style/.expanded=\pos]{}};
+\end{tikzpicture}
+\end{codeexample}
+
+\subsection{Parabola}
+\indexPathOperationO{parabola}%
+
+For the |parabola| path operator the timer is similar to the |.. controls ..| operator.
+
+The position 0.5 will lie at the |bend|.
+\begin{codeexample}[width=.3\linewidth,preamble=\usetikzlibrary{ext.paths.timer}]
+\begin{tikzpicture}
+\draw[help lines]  (-2.25, -1.25) grid (2.25, 3.25);

+    node[
+      pos=.\pos, sloped, fill=white, font=\small, inner sep=+0pt
+    ] {\pos}
+  };
+\end{tikzpicture}
+\end{codeexample}
+
+If no |bend| is specified half the positions will collapse into one end of the curve.
+
+\begin{codeexample}[width=.3\linewidth,preamble=\usetikzlibrary{ext.paths.timer}]
+\begin{tikzpicture}[every pin edge/.style={latex-, shorten <=1pt, gray}]
+\draw (-2,-2) parabola (1,0)
+  foreach \pos in {0, 1, ..., 10} {
+    node [pos=\pos/10, pin={[anchor=-18*\pos+90]-18*\pos+270:\pos}]{}
+  };
+\end{tikzpicture}
+\end{codeexample}
+
+\subsection{Sine/Cosine}
+\indexPathOperationO{sin}\indexPathOperationO{cos}%
+
+The |sin| and |cos| path operators also allow placing of nodes along their paths.
+
+\begin{codeexample}[width=.3\linewidth,preamble=\usetikzlibrary{ext.paths.timer}]
+\begin{tikzpicture}[mark nodes on line/.style={insert path={
+  foreach \pos in {1, ..., 9} {node[

+\section{Using Images as a Pattern}
+\label{library:patterns.images}
+
+\begin{tikzlibrary}{ext.patterns.images}
+  This library allows to use an image to be used as a repeating pattern for a path.
+\end{tikzlibrary}
+
+With this library arbitrary images (or indeed PDF documents) can be used as
+a repeating pattern for the background of a path.
+
+This is a two-step process:
+\begin{enumerate}
+\item Declaring an image as an ``image-pattern''.
+\item Using the ``image-pattern''.
+\end{enumerate}
+
+\begin{command}{\pgfsetupimageaspattern\oarg{options}\marg{name}\marg{image}}
+\end{command}
+
+\begin{key}{/tikz/image as pattern=\meta{options} (default |\{\}|)}
+
+\begin{codeexample}[preamble=\usetikzlibrary{ext.patterns.images}]
+\pgfsetupimageaspattern[width=.5cm]{grid}{example-image-1x1}
+\tikz \node[star, minimum size=3cm, draw,
+  image as pattern={name=grid,options={left, bottom, y=-.5cm, rotate=45}}] {};
+\end{codeexample}
+\end{key}
+
+\begin{key}{/tikz/image as pattern/name=\meta{name}}
+Specifies the name of the ``image-pattern'' to be used.
+\end{key}
+
+\begin{stylekey}{/tikz/image as pattern/option}
+Options that's be used by the internal |\pgftext|,\indexCommandO{\pgftext}
+only keys from |/pgf/text| should be used.\indexKeyO[/pgf/]{text}
+\end{stylekey}
+
+\begin{stylekey}{/tikz/image as pattern/options=\meta{style}}
+Appends style |/tikz/image as pattern/option|.

+\section{Positioning Plus}
+\label{library:positioning-plus}
+\tikzsetnextfilename{posplus}
+\begin{tikzlibrary}{ext.positioning-plus}
+  With the help of the |positioning|\indexLibrary{positioning} and the |fit|\indexLibrary{fit} library this extends the placement of nodes.
+\end{tikzlibrary}
+
+\subsection{Useful corner anchors}
+The anchors |corner north east|, |corner north west|, |corner south west| and |corner south east|
+are defined as ``generic anchors'', i.\,e. they are defined for all shapes.
+This is mostly useful for the placement of circular shapes.
+\begin{stylekey}{/tikz/corner above left=\opt{\meta{specification}} (default 0pt)}
+  Similar as \referenceKeyandIndexO{above left} of the \tikzname\space library |positioning|
+  but uses the |corner north west| anchor.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner below left=\opt{\meta{specification}} (default 0pt)}
+  Similar as \referenceKeyandIndexO{below left} of the \tikzname\space library |positioning|

+\end{stylekey}
+
+The same exist for the recently introduces corner anchors, too.
+\begin{stylekey}{/tikz/corner north left=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/north left| but uses the new corner anchors.
+\end{stylekey}

+\begin{stylekey}{/tikz/corner south left=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/south left| but uses the new corner anchors.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner south right=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/south right| but uses the new corner anchors.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner west above=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/west above| but uses the new corner anchors.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner west below=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/west below| but uses the new corner anchors.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner east above=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/east above| but uses the new corner anchors.
+\end{stylekey}
+\begin{stylekey}{/tikz/corner east below=\opt{\meta{specification}} (default 0pt)}
+  The same as |/tikz/east below| but uses the new corner anchors.
+\end{stylekey}
+
+While the \meta{specification} of all these keys still accept the same form as with \tikzname,
+the |ext.positioning-plus| library extends this even more.
+
+The specification after |of| can contain a list of coordinates
+(like the |fit| key of the |fit| library).
+This means that the new node will be placed in relation to a rectangular bounding box
+that fits around all this nodes in the list.
+
+If this list is prefixed with \verb!|!, |-| or |+|,
+the new node will also have the same height (\verb!|!),
+the same width (|-|) or both as this bounding box.
+
+\begin{codeexample}[preamble=\usetikzlibrary{ext.positioning-plus}]
+\begin{tikzpicture}[nodes=draw]
+\node                     (A) {A};
+\node[below=of A]         (BCD) {BCD};
+\node[right=of |(A)(BCD)] (c) {};
+\node[below=.5:of -(A)(BCD)] (d) {};
+\draw[help lines] (BCD.south west) -- (c.south east)
+                  (BCD.north east) -- (d.south east);
+\end{tikzpicture}
+\end{codeexample}
+
+This functionality is also available without the placement:
+\begin{stylekey}{/tikz/fit bounding box=\meta{list of coordinates}}
+  Creates a rectangular node with the name |fit bounding box| that encompasses
+  the \meta{list of coordinates}.
+\end{stylekey}
+\begin{stylekey}{/tikz/span vertical=\meta{list of coordinates}}
+  Creates a rectangular node with the name |fit bounding box| that encompasses
+  the \meta{list of coordinates} \emph{and} sets the \referenceKeyandIndexO[/pgf]{minimum height} to
+  the height of this bounding box.
+\end{stylekey}
+\begin{stylekey}{/tikz/span horizontal=\meta{list of coordinates}}
+  Creates a rectangular node with the name |fit bounding box| that encompasses
+  the \meta{list of coordinates} \emph{and} sets the \referenceKeyandIndexO[/pgf]{minimum width} to
+  the width of this bounding box.
+\end{stylekey}
+\begin{stylekey}{/tikz/span=\meta{list of coordinates}}
+  Is a combination of |/tikz/span vertical| and |/tikz/span horizontal|.
+\end{stylekey}
+
+As you maybe noticed in the example above, the \meta{specification} also allows a prefix
+delimited by |:| which the |node distance| will be multiplied to with for the placement.%
+\footnote{This is probably more useful when \referenceKeyandIndexO{on grid} is used.}

+\section{Mirror, Mirror on the Wall}
+\label{library:mirror}
+
+\begin{tikzlibrary}{ext.transformations.mirror}
+  This library adds more transformations to \tikzname.
+\end{tikzlibrary}
+
+As explained in section~\ref{pgflibrary:transformations}, there are two approaches to setting a mirror transformation.
+As with the commands in PGF, we'll be using a lowercase |m| for the reflection matrix and an uppercase |M| for the built-in approach.
+
+\subsection{Using the reflection matrix}
+
+\begin{codeexample}[width=.4\linewidth,preamble=\usetikzlibrary{shapes.geometric,ext.transformations.mirror}]
+\begin{tikzpicture}[line join=round, thick, reg poly/.style={
+  shape=regular polygon, regular polygon sides={#1}}]
+\node[reg poly=5, minimum size=+2cm, draw, very thick] (a) {};
+\foreach \i[evaluate={\col=(\i-1)/.04}] in {1,...,5}
+  \node [mirror=(a.corner \i)--(a.side \i), transform shape,
+         reg poly=5, minimum size=+2cm, draw=red!\col!blue] {};
+\end{tikzpicture}
+\end{codeexample}
+
+\begin{key}{/tikz/xmirror=\meta{value or coordinate}}
+  Sets up a transformation that mirrors along a horizontal line that goes through point $(\text{\meta{value}}, 0)$ or \meta{coordinate}.
+
+\begin{codeexample}[preamble=\usetikzlibrary{ext.transformations.mirror}]
+\begin{tikzpicture}
+\draw[help lines] (-0.25, -.25) grid (3.25, 1.25);
+\draw[-latex] (0,0) .. controls (.5,1) .. (1,1);
+
+\draw[dashed] (1.5, -.25) coordinate (m) -- (1.5, 1.25);
+\draw[xmirror=(m),-latex] (0,0) .. controls (.5,1) .. (1,1);
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+
+\begin{key}{/tikz/ymirror=\meta{value or coordinate}}
+  Sets up a transformation that mirrors along a vertical line that goes through point $(0, \text{\meta{value}})$ or \meta{coordinate}.
+\end{key}
+
+
+\begin{key}{/tikz/mirror x=\meta{coordinate}}
+  Similar to |/tikz/xmirror|, this however uses the |xyz| coordinate system instead of the |canvas| system.
+\begin{codeexample}[preamble=\usetikzlibrary{ext.transformations.mirror}]
+\begin{tikzpicture}[x=.5cm, y=(45:1cm)]
+
+\draw[-latex] (0,0) .. controls (.5,1) .. (1,1);
+
+\draw[dashed] (1.5, -.25) coordinate (m) -- (1.5, 1.25);
+
+\draw[ xmirror=(m), -latex, red, dotted] (0,0) .. controls (.5,1) .. (1,1);
+\draw[mirror x=(m), -latex]              (0,0) .. controls (.5,1) .. (1,1);
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+
+\begin{key}{/tikz/mirror y=\meta{coordinate}}
+  Similar to |/tikz/ymirror|, this however uses the |xyz| coordinate system instead of the |canvas| system.
+\end{key}
+
+
+\begin{key}{/tikz/mirror=\meta{point A}|--|\meta{point B}}
+  Sets up a transformation that mirrors along a line that goes through \meta{point A} and \meta{point B}.
+  
+  When only \meta{point A} is given that line goes through \meta{point A} and the origin.
+\end{key}
+
+\subsection{Using built-in transformations}
+
+\begin{codeexample}[width=.4\linewidth,preamble=\usetikzlibrary{shapes.geometric,ext.transformations.mirror}]
+\begin{tikzpicture}[line join=round, thick, reg poly/.style={
+  shape=regular polygon, regular polygon sides={#1}}]

+         reg poly=5, minimum size=+2cm, draw=red!\col!blue] {};
+\end{tikzpicture}
+\end{codeexample}
+
+\begin{key}{/tikz/xMirror=\meta{value or coordinate}}
+  Sets up a transformation that mirrors along a horizontal line that goes through point $(\text{\meta{value}}, 0)$ or \meta{coordinate}.

+\draw[dashed] (1.5, -.25) coordinate (m) -- (1.5, 1.25);
+\draw[xMirror=(m),-latex] (0,0) .. controls (.5,1) .. (1,1);
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+
+\begin{key}{/tikz/yMirror=\meta{value or coordinate}}
+  Sets up a transformation that mirrors along a vertical line that goes through point $(0, \text{\meta{value}})$ or \meta{coordinate}.
+\end{key}
+
+
+\begin{key}{/tikz/Mirror x=\meta{coordinate}}
+  Similar to |/tikz/xMirror|, this however uses the |xyz| coordinate system instead of the |canvas| system.

+\section{Transformations: Mirroring}
+\label{pgflibrary:transformations}
+
+\begin{purepgflibrary}{ext.transformations.mirror}
+  This library adds mirror transformations to PGF.
+\end{purepgflibrary}
+
+Two approaches to mirror transformation exist:
+\begin{enumerate}
+\item Using the reflection matrix (see left column).
+
+  This depends on |\pgfpointnormalised|\indexCommandO\pgfpointnormalised which involves
+  the sine\indexMathFunctionO{sin} and the cosine\indexMathFunctionO{cos} functions of PGFmath.
+
+\item Using built-in transformations (see right column).
+
+  This depends on |\pgfmathanglebetween|\indexCommandO\pgfmathanglebetween which involves the arctangent (|atan2|\indexMathFunctionO{atan2}) function of PGFmath.
+\end{enumerate}
+
+Which one is better? I don't know.
+Choose one you're comfortable with.
+
+\begin{paracol}{2}
+
+\subsection{Using the reflection matrix}
+
+The following commands use the reflection matrix that sets the transformation matrix following
+\begin{equation*}
+  A = \frac{1}{\Vert\vec l\Vert^2} \begin{bmatrix}
+  l_x^2-l_y^2 & 2l_xl_y \\
+  2l_xl_y & l_y^2-l_x^2\\
+  \end{bmatrix}.
+\end{equation*}
+
+\switchcolumn% >
+
+\stepcounter{subsection}
+\subsection{Using built-in transformations}
+
+The following commands use a combination of shifting, rotating, $-1$ scaling,
+rotating back and shifting back to reach the mirror transformation.
+
+The commands are named the same as on the left side,
+only the |m| in |mirror| is capitalized.
+
+\switchcolumn*% <
+
+\begin{command}{\pgftransformxmirror\marg{value}}
+  Sets up a transformation that mirrors along a vertical line that goes through point $(\text{\meta{value}}, 0)$.
+
