-%   Writes the \meta{content} as content of the \meta{object}. Depending on the

-%   \meta{data} will vary
-%   \begin{itemize}
-%     \item[\texttt{array}] A space-separated list of values
-%     \item[\texttt{dict}] Key--value pairs in the form

-%   \begin{itemize}
-%     \item[\texttt{array}] A space-separated list of values

-%     \cs{pdf_object_last:}
-%   \end{syntax}
-%   Inserts the appropriate information to reference the last \meta{object}
-%   created. This is particularly useful for anonymous objects.
-% \end{function}
-%
-% \subsection{Version}
-%
-% \begin{function}[pTF, EXP, added = 2019-06-02]{\pdf_version_compare:Nn}
-%   \begin{syntax}
-%     \cs{pdf_version_compare:NnTF} \meta{comparator} \Arg{version} \Arg{true code} \Arg{false code}
-%   \end{syntax}
-%   Compares the version of the PDF being created with the \meta{version}
-%   string specified, using the \meta{comparator}. Either the \meta{true code}
-%   or \meta{false code} will be left in the output stream.
-% \end{function}
-%
-% \begin{function}[added = 2019-06-02]
-%   {\pdf_version_gset:n, \pdf_version_min_gset:n}
-%   \begin{syntax}
-%     \cs{pdf_version_gset:n} \Arg{version}
-%   \end{syntax}
-%   Sets the \meta{version} of the PDF being created. The |min| version will
-%   not alter the output version unless it is currently lower than the
-%   \meta{version} requested.
-%
-%   This function may only be used up to the point where the PDF file is
-%   initialised.
-% \end{function}
-%
-% \begin{function}[EXP, added = 2019-06-02]
-%   {\pdf_version:, \pdf_version_major:, \pdf_version_minor:}
-%   \begin{syntax}
-%     \cs{pdf_version:}
-%   \end{syntax}
-%   Expands to the currently-active PDF version.
-% \end{function}
-%
-% \subsection{Compression}
-%
-% \begin{function}[added = 2019-06-02]{\pdf_uncompress:}
-%   \begin{syntax}
-%     \cs{pdf_uncompress:}
-%   \end{syntax}
-%   Disables any compression of the PDF, where possible.
-%
-%   This function may only be used up to the point where the PDF file is
-%   initialised.
-% \end{function}
-%
-% \subsection{Destinations}
-%
-% Destinations are the places a link jumped too.
-% Unlike the name may suggest they don't described
-% an exact location in the PDF. Instead a destination contains a reference to
-% a page along with an instruction how to display this page.
-% The normally used \enquote{XYZ \textit{top left zoom}} for example instructs
-% the viewer to show the page with the given \textit{zoom} and
-% the top left corner at the \textit{top left} coordinates---which then gives
-% the impression that there is an anchor at this position.
-%
-% If an instruction takes a coordinate, it is calculated by the following
-% commands relative to the location the command is issued.
-% So to get a specific coordinate one has to move the command to the right place.
-%
-% \begin{function}[added = 2021-01-03]
-%   {\pdf_destination:nn}
-%   \begin{syntax}
-%     \cs{pdf_destination:nn} \Arg{name} \Arg{type or integer}
-%   \end{syntax}
-%   This creates a destination. \Arg{type or integer} can be one of |fit|, |fith|,
-%   |fitv|, |fitb|, |fitbh|, |fitbv|, |fitr|, |xyz|
-%   or an integer representing a  scale factor in percent.
-%   |fitr| here gives only a lightweight version of |/FitR|:
-%   The backend code defines |fitr| so that it will with pdf\LaTeX{} and
-%   Lua\LaTeX{} use the coordinates of the surrounding box,
-%   with \texttt{dvips} and \texttt{dvipdfmx} it falls back to |fit|.
-%   For full control use \cs{pdf_destination:nnnn}.
-%
-%   The keywords match to the PDF names as described in the following tabular.
-%
-%   \medskip
-%   \noindent\begin{tabular}{ll>{\raggedright\arraybackslash}p{6cm}}
-%   \toprule
-%   Keyword & PDF & Remarks \\ \midrule
-%   |fit|  & |/Fit|
-%      & Fits the page to the window\\
-%   |fith| & |/FitH|  \textit{top}
-%      & Fits the width of the page to the window \\
-%   |fitv| & |/FitV|  \textit{left}
-%      & Fits the height of the page to the window \\
-%   |fitb| & |/FitB|
-%      & Fits the page bounding box to the window \\
-%   |fitbh|& |/FitBH| \textit{top}
-%      & Fits the width of the page bounding box to the window. \\
-%   |fitbv|& |/FitBV| \textit{left}
-%      & Fits the height of the page bounding box to the window. \\
-%   |fitr| & |/FitR| \textit{left bottom right top}
-%      & Fits the rectangle specified by the four coordinates to the window
-%        (see above for the restrictions)\\
-%   |xyz|  & |/XYZ|  \textit{left top} null
-%      & Sets a coordinate but doesn't change the zoom.\\
-%   \Arg{integer} & |/XYZ|  \textit{left top zoom}
-%      & Sets a coordinate and a zoom meaning \Arg{integer}\%.
-%    \\\bottomrule
-%   \end{tabular}
-%
-% \end{function}
-%
-% \begin{function}[added = 2021-01-17]
-%   {\pdf_destination:nnnn}
-%   \begin{syntax}
-%     \cs{pdf_destination:nnnn} \Arg{name} \Arg{width} \Arg{height} \Arg{depth}
-%   \end{syntax}
-%   This creates a destination with |/FitR| type with the given dimensions relative
-%   to the current location. The destination is in a box of size zero, but it doesn't
-%   switch to horizontal mode.
