+%
+% \section{Documentation}
+%
+% \subsection{Drawing pictures}
+%
+% \pxpicname\ supports different input modes, all of them have the same basic
+% parsing behaviour. A \meta{pixel list} contains the pixel colours. The image
+% is built line wise from top left to bottom right. Each row of pixels should be
+% a single \TeX\ argument (so either just one token, or a group delimited by
+% |{}|), and within each line each pixel in turn should be a single \TeX\
+% argument (so either just one token, or a group delimited by |{}|). Spaces and
+% hence single newlines in the sources between \meta{pixel list} elements are
+% ignored. The different modes are explained in \autoref{sec:modes}. The only
+% disallowed token in the \meta{pixel list} is the control sequence
+% \CS{pxpic@end} (plus the usual restrictions of \TeX\ so no unbalanced braces,
+% no macros defined as \CS{outer}).
+%
+% There is a small caveat however: \pxpicname\ draws each pixel individually,
+% and there is really no space between them, however some \textsc{pdf} viewers
+% fail to display such adjacent lines correctly and leave small gaps (basically
+% the same issue which packages like \pkg{colortbl} suffer from as well). In
+% print this shouldn't be an issue, but some rasterisation algorithms employed
+% by viewers and conversion tools have this deficit.
+%
+% \begin{function}{\pxpic}
+%   \begin{syntax}
+%     \cs{pxpic}\oarg{options}\marg{pixel list}
+%   \end{syntax}
+%   \meta{options} might be any options as listed in \autoref{sec:options}, and
+%   \meta{pixel list} is a list of pixels as described above. \cs{pxpic} parses
+%   the \meta{pixel list} and draws the corresponding picture. The result is
+%   contained in an \CS{hbox} and can be used wherever \TeX\ expects an
+%   \CS{hbox}. As a result, when you're in vertical mode a \cs{pxpic} will form
+%   a text line, to prevent this you can use \CS{leavevmode} before it. The
+%   \cs{pxpic} will be bottom aligned, you can change this using \CS{raisebox}
+%   (or, if you want, \TeX's \CS{raise} and \CS{lower} primitives).
+% \end{function}
+%
+% \subsubsection{Examples}
+%
+% Since the above explanation of the \meta{pixel list} syntax might've been a
+% bit cryptic, and a good documentation should contain examples (this doesn't
+% claim this documentation is \emph{good}), well, here are some examples (you
+% might need to take a look at \autoref{sec:options} and \autoref{sec:modes} to
+% fully understand the examples). Examples in this section will use the
+% following \CS{pxpicsetup}:

+%
+% \subsection{Setting options}\label{sec:options}
+%
+% To control its behaviour \pxpicname\ uses a key=value interface powered by
+% \expkv. Options can be set either in the optional argument of
+% \CS{pxpic} or with
+%
+% \begin{function}{\pxpicsetup}
+%   \begin{syntax}
+%     \cs{pxpicsetup}\marg{options}
+%   \end{syntax}
+%   Sets the \meta{options} locally to the current \TeX\ group.
+% \end{function}
+%
+% \medskip\noindent
+% Package options are not supported.
+%
+% \bigskip
+% The available options are
+%
+% \begin{options}
+%   \item[colors] Define pixel colours for |mode=px|, see \autoref{sec:colours}
+%     for a description of the value's syntax. No pixel definitions are made by
+%     the package.
+%   \item[colours] \emph{see \texttt{colors}.}
+%   \item[ht] Set the height of the pixels.
+%   \item[mode] Set the used mode, see \autoref{sec:modes} for available modes.
+%     Initial value is |px|.
+%   \item[size] Set both |ht| and |wd|. Initial value is \the\pxpicHT.
+%   \item[skip] Define the value to be a skip (an empty space of width |wd|) in
+%     |mode=px|. No skip definitions are made by the package.
+%   \item[wd] Set the width of the pixels.
+% \end{options}
+%
+% \subsubsection{Colour syntax}\label{sec:colours}
+%
+% In the value of the |colours| option you'll have to use the following syntax.
+% Use a comma separated key=value list in which each key corresponds to a new
+% pixel name for |mode=px|, and each value to the used colour. If the colour
+% starts with an opening bracket use the complete value as is behind \CS{color},
+% else use the whole value as the first mandatory argument to \CS{color} with a
+% set of braces added. For example to define |r| as the named colour |red|, and
+% |x| as the colour |#abab0f| (in the \textsc{html} colour model) use:
+% \begin{lstlisting}
+% colours = {r=red, x=[HTML]{abab0f}}
+% \end{lstlisting}
+%
+% \subsubsection{Available modes}\label{sec:modes}
+%
+% \begin{options}
+%   \item[px]
+%     As already mentioned, \pxpicname\ supports different modes of input. The
+%     easiest to use |mode| is |px|, in which each element of the \meta{pixel
+%     list} has been previously defined as either a coloured pixel (using the
+%     |colour| option) or as a skipped pixel (using the |skip| option, resulting
+%     in a fully transparent pixel). Each element will be \CS{detokenize}d, so
+%     (within \TeX's limitations) the name of a pixel can be arbitrary. This is
+%     the initial mode \pxpicname\ uses. But other options are available as
+%     well.
+%   \item[named]
+%     Another |mode| is |named|, in which each element of the \meta{pixel list}
+%     should be a named colour (or colour expression) known to \pkg{xcolor}.
+%     Each element will be used like so: |{\color{|\meta{element}|}\px}|. An
+%     exception is an element which is empty (|{}|), which will be a skipped
+%     pixel.
+%   \item[rgb, cmy, cmyk, hsb, Hsb, tHsb, gray, RGB, HTML, HSB, Gray, wave]
+%     The modes |rgb|, |cmy|, |cmyk|, |hsb|, |Hsb|, |tHsb|, |gray|, |RGB|,
+%     |HTML|, |HSB|, |Gray|, and |wave| correspond to the different colour
+%     models supported by \pkg{xcolor}. With these modes each element of the
+%     \meta{pixel list} will be the values in these colour models, so they'll be
+%     used like so: |{\color[|\meta{mode}|]{|\meta{element}|}\px}|. An
+%     exception is an element which is empty (|{}|), which will be a skipped
+%     pixel.
+% \end{options}
+%
+% You can define additional modes selectable with the |mode| option using the
+% macros |\pxpicnewmode| or |\pxpicsetmode|.
+%
+% \subsection{Other customisation macros}
+%
+% \begin{function}{\pxpicnewmode,\pxpicsetmode}
+%   \begin{syntax}
+%     \cs{pxpicnewmode}\marg{name}\marg{definition}
+%   \end{syntax}
+%   You can define your own modes with \cs{pxpicnewmode}. Inside
+%   \meta{definition} |#1| is the currently parsed item in the \CS{pxpic}
+%   \meta{pixel list}. You can output a pixel using \CS{px}, and skip a pixel
+%   using \CS{pxskip}. The pixel will use the currently active colour (so if you
+%   want to draw a red pixel you could use |{\color{red}\px}|).
+%   \cs{pxpicnewmode} will throw an error if you try to define a mode which
+%   already exists, \cs{pxpicsetmode} has no checks on the name.
+% \end{function}
+%
+% \begin{function}{\pxpicforget}
+%   \begin{syntax}
+%     \cs{pxpicforget}\marg{px}
+%   \end{syntax}
+%   Undefines the \meta{px} definition for use in |mode=px| (or skip symbol)
+%   added with the |colours| (or |skip|) option.
+% \end{function}
+%
+% \subsection{Other macros}
+%
+% \begin{function}{\px,\pxskip}
+%   Inside of a \CS{pxpic} the macro \cs{px} draws a pixel (of the currently
+%   active colour), and \cs{pxskip} leaves out a pixel (so this one pixel is
+%   fully transparent). Use this in the \meta{definition} of a mode in
+%   \CS{pxpicnewmode}.
+% \end{function}
+%
+% \begin{variable}{\pxpicHT,\pxpicWD}
+%   These two are |dimen| registers storing the height and width of the pixels.
+% \end{variable}
+%
+% \begin{function}{\pxpiclogo}
+%   \begin{syntax}
+%     \cs{pxpiclogo}\oarg{size}
+%   \end{syntax}
+%   This draws the logo of \pxpicname. The \meta{size} controls the pixel size.
+% \end{function}
+%
+% \subsection{Miscellaneous}
+%
+% If you find bugs or have suggestions I'll be glad to hear about it, you can
+% either open a ticket on Github (\url{https://github.com/Skillmon/ltx_pxpic})
+% or email me (see the first page).
+%
+% A similar package is \pkg{pixelart}, which, as of writing this, is described
+% as a ``working draft'' by its author. \pxpicname\ wasn't intended as a direct
+% competitor (I already started coding \pxpicname\ when I learned about
+% \pkg{pixelart}'s existence), but I took inspiration from the ``Bugs, Ideas,
+% Undefined behaviours'' section of \pkg{pixelart}'s documentation for the
+% syntax of |mode=px|.

+%
+%
+% \subsection{Options}
+%
+% We define the options using \expkv\ directly (no fancy options are involved
+% and these are just a few anyway).
+%
+% The first few options are straight forward. We use \expkv's name space to
+% actually store the |skip| and |px| definitions, hence we use
+% \CS{ekvdefNoVal} in the code of |skip|.
+%
+%    \begin{macrocode}
+\protected\ekvdef{pxpic}{size}
+  {\pxpicHT=\dimexpr#1\relax\pxpicWD=\dimexpr#1\relax}
+\protected\ekvdef{pxpic}{ht}{\pxpicHT=\dimexpr#1\relax}
+\protected\ekvdef{pxpic}{wd}{\pxpicWD=\dimexpr#1\relax}
+\protected\ekvdef{pxpic}{skip}{\ekvdefNoVal{pxpic@px}{#1}{\pxskip}}
+%    \end{macrocode}
+% The |colours| option is parsed using \CS{ekvparse} and \CS{pxpic@setcolor}.
+%    \begin{macrocode}
+\protected\ekvdef{pxpic}{colors}{\ekvparse\pxpic@noval\pxpic@setcolor{#1}}
+\ekvletkv{pxpic}{colours}{pxpic}{colors}
+%    \end{macrocode}
+% And the |mode| just checks whether the |mode| macro is defined and lets the
+% auxiliary macro \CS{pxpic@parse@px} to the defined |mode|.
+%    \begin{macrocode}
+\protected\ekvdef{pxpic}{mode}
+  {%
+    \@ifundefined{pxpic@parse@px@#1}%
+      {\pxpic@unknown@mode{#1}}%
+      {%
+        \expandafter\let\expandafter\pxpic@parse@px
+          \csname pxpic@parse@px@#1\endcsname
+      }%
+  }
+%    \end{macrocode}
+%
+%
+% \subsection{User macros}\label{sec:implementation:pxpiclogo}
+%
+% \begin{macro}{\pxpic}
+% \begin{macro}[internal]{\pxpic@}
+%   \CS{pxpic} expands directly to an opened \CS{hbox}, the auxiliary
+%   \CS{pxpic@} checks for the optional argument and inserts the rest of the
+%   code. We need to set \CS{baselineskip} to \CS{pxpicHT} so that the pixels
+%   are stacked vertically without gaps. \CS{pxpic@parse} will parse the
+%   \meta{pixel list} until \CS{pxpic@end} is hit. The final \CS{egroup} closes
+%   the \CS{hbox}. The row-wise output is done via a \CS{vbox} in which each
+%   pixel row will be wrapped inside an \CS{hbox}.
+%    \begin{macrocode}
+\newcommand*\pxpic{\hbox\bgroup\pxpic@}
+\newcommand\pxpic@[2][]
+  {%
+    \vbox

+        \pxpic@parse#2\pxpic@end
+      }%
+    \egroup
+  }
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\pxpicsetup}
+%   Just directly defined to call \expkv's parser for the \pxpicname\ set.
+%    \begin{macrocode}
+\ekvsetdef\pxpicsetup{pxpic}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\pxpiclogo}
+%   The logo is just a biggish pixel picture. The \CS{lower} will move it down a
+%   bit so that it appears correctly aligned on the baseline. Since the logo
+%   should be part of a normal sentence in most usages we put \CS{leavevmode}
+%   before it. Also we make sure that the |mode| and |px| definitions are
+%   correct.
+%    \begin{macrocode}

+%
+% \begin{macro}{\pxpicnewmode,\pxpicsetmode}
+%   These are pretty simple as well, the |new| variant will use \CS{newcommand}
+%   which will do the testing for us, the |set| variant uses \CS{def}.
+%    \begin{macrocode}
+\protected\def\pxpicnewmode#1#2%
+  {\expandafter\newcommand\csname pxpic@parse@px@#1\endcsname[1]{#2}}
+\protected\def\pxpicsetmode#1#2%

+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \subsection{Parser}
+%
+% \begin{macro}[internal]{\pxpic@ifend,\pxpic@ifempty,\pxpic@ifbracket}
+%   These are three helper macros. The first just gobbles everything until the
+%   next \CS{pxpic@end}, and we borrow a fast test for an empty argument from
+%   \expkv. The last can be used to check for an opening bracket if used like
+%   |\pxpic@ifbracket|\hskip0pt|\pxpic@end|\hskip0pt|#1.\pxpic@end|\hskip0pt
+%   |[]\pxpic@end|.
+%    \begin{macrocode}
+\long\def\pxpic@ifend#1\pxpic@end{}

+\long\def\pxpic@ifbracket#1\pxpic@end[#2]\pxpic@end{\pxpic@ifempty{#2}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}[internal]{\pxpic@parse,\pxpic@done}
+%   The parsing loop is pretty simple, first check whether we're done, else open
+%   a new \CS{hbox} (which will form a row in the \CS{vbox} placed by
+%   \CS{pxpic@}) in which the inner parsing loop is run. Then call the next
+%   iteration. If we're done just gobble the remainder of the current iteration.
+%    \begin{macrocode}
+\newcommand\pxpic@parse[1]
+  {%
+    \pxpic@ifend#1\pxpic@done\pxpic@end
+    \hbox{\pxpic@parseline#1\pxpic@end}%
+    \pxpic@parse
+  }
+\long\def\pxpic@done\pxpic@end\hbox#1\pxpic@parse{}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}[internal]{\pxpic@parseline,\pxpic@linedone}
+%   The line parsing loop also checks whether we're done, if not we place a
+%   pixel using the current definition of \CS{pxpic@parse@px} (which will be set
+%   by the current |mode|) and afterwards call the next iteration. If we're done
+%   we gobble the remainder of the current iteration and control goes back to
+%   \CS{pxpic@parse}.
+%    \begin{macrocode}
+\newcommand\pxpic@parseline[1]
+  {%
+    \pxpic@ifend#1\pxpic@linedone\pxpic@end
+    \pxpic@parse@px{#1}%
+    \pxpic@parseline
+  }
+\long\def\pxpic@linedone\pxpic@end\pxpic@parse@px#1\pxpic@parseline{}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \subsection{Modes}
+%
+% The modes define how a single element of the \meta{pixel list} is parsed.
+%
+% \begin{macro}[internal]{\pxpic@parse@px@px,\pxpic@parse@px}
+%   In the |px| mode we check whether the pixel is defined (using the name space
+%   of \expkv), if so call it, else throw an error and skip. Since this is also
+%   the initial |mode| we \CS{let} the auxiliary macro \CS{pxpic@parse@px} to
+%   this mode here.
+%    \begin{macrocode}
+\newcommand\pxpic@parse@px@px[1]
+  {%
+    \ekvifdefinedNoVal{pxpic@px}{#1}
+      {\csname\ekv@name{pxpic@px}{#1}N\endcsname}%
+      {%
+        \pxpic@unknown@px{#1}%
+        \pxskip
+      }%
+  }
+\let\pxpic@parse@px\pxpic@parse@px@px
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}[internal]{\pxpic@parse@px@named}
+%   |named| just checks whether the skip is empty. If so skip, else call
+%   \CS{color} with the element and output a pixel.
+%    \begin{macrocode}
+\newcommand\pxpic@parse@px@named[1]
+  {%
+    \pxpic@ifempty{#1}
+      {\pxskip}
+      {{\color{#1}\px}}%
+  }
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}[internal]
+%   {
+%     \pxpic@parse@px@rgb,
+%     \pxpic@parse@px@cmy,
+%     \pxpic@parse@px@cmyk,
+%     \pxpic@parse@px@hsb,
+%     \pxpic@parse@px@Hsb,
+%     \pxpic@parse@px@tHsb,
+%     \pxpic@parse@px@gray,
+%     \pxpic@parse@px@RGB,
+%     \pxpic@parse@px@HTML,
+%     \pxpic@parse@px@HSB,
+%     \pxpic@parse@px@Gray,
+%     \pxpic@parse@px@wave
+%   }
+%  The colour model modes are all the same in principle. They test for an empty
+%  element to introduce a skip, else they call \CS{color} with the respective
+%  colour model and output a pixel. We use the auxiliary \CS{pxpic@tmp} to do
+%  all those definitions and undefine it afterwards.
+%    \begin{macrocode}
+\def\pxpic@tmp#1%
+  {%
+    \pxpicnewmode{#1}%
+      {%
+        \pxpic@ifempty{##1}

+          {{\color[#1]{##1}\px}}%
+      }%
+  }

+%
+%
+% \subsection{Pixel and Skip}
+%
+% \begin{macro}[internal]{\pxpic@px,\pxpic@skip}
+%   The actual definition of pixels and skips is stored in macros to which the
+%   frontend macros \CS{px} and \CS{pxskip} will be let inside of \CS{pxpic}.

+%
+%
+% \subsection{Parser for colours}
+%
+% \begin{macro}[internal]{\pxpic@setcolor,\pxpic@setcolor@a,\pxpic@setcolor@b}
+%   First we test whether the colour starts with an opening bracket or not.
+%   Depending on that we either just put the colour after \CS{color}, or put
+%   braces around it (as it then is a colour expression for \pkg{xcolor} and
+%   just a single argument). \CS{pxpic@setcolor} defines a |px| in the name
+%   space of \expkv\ (this has a slight overhead during definition, but \expkv\
+%   is fast in checking whether one of its keys is defined or not, and reduces
+%   the amount of code in this package).
+%    \begin{macrocode}
+\newcommand\pxpic@setcolor[2]
+  {%
