+%
+% \subsection{Driver functions}
+%
+% Inclusion of graphic files requires a range of low-level data be passed to
+% the driver layer. These functions are primarily aimed at supporting this
+% work.
+%
+% \begin{variable}{\l_graphics_decodearray_tl}
+%   Array to decode color in bitmap graphic: when non-empty, this should
+%   be in the form of one, two or three pairs of real numbers in the range
+%   $[0,1]$, separated by spaces.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_interpolate_bool}
+%   Indicates whether interpolation should be applied to bitmap graphic files.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_page_int}
+%   The page to extract from a multi-page graphic file: used for |.pdf| files
+%   which may contain multiple pages.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_pagebox_tl}
+%   The nature of the page box setting used to determine the bounding box of
+%   material: used for |.pdf| files which feature multiple page box
+%   specifications.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_draft_bool}
+%   Switch to enable draft mode: graphics are read but not included when this is
+%   true.
+% \end{variable}
+%
+% \begin{variable}
+%   {\l_graphics_llx_dim, \l_graphics_lly_dim, \l_graphics_urx_dim, \l_graphics_ury_dim}
+%   Dimensions which return the points $(\meta{llx},\meta{lly})$ and
+%   $(\meta{urx},\meta{ury})$ for the graphic. For many graphics only the resulting
+%   height and width are significant, but this is driver-dependent.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_name_bool}
+%   The name of a graphics file being loaded: usually the same as the
+%   input file name, but may be altered by some drivers.
+% \end{variable}
+%
+% \begin{function}
+%   {
+%     \graphics_bb_save:n, \graphics_bb_save:x,
+%     \graphics_bb_restore:nF, \graphics_bb_restore:xF
+%   }
+%   \begin{syntax}
+%     \cs{graphics_bb_save:n} \Arg{graphic}
+%     \cs{graphics_bb_restore:nF} \Arg{graphic} \Arg{false code}
+%   \end{syntax}
+%   This pair of functions are used to cache the bounding box of an \meta{graphic}
+%   so that extraction/reading is only required once. The \texttt{save}
+%   function stores the values from \cs{l_graphics_llx_dim},
+%   \cs{l_graphics_lly_dim}, \cs{l_graphics_urx_dim} and
+%   \cs{l_graphics_ury_dim} as constants. The \texttt{restore} function will then
+%   look up values for the bounding box of an \meta{graphic} and set the four
+%   dimensions appropriately. For any one \meta{graphic} the bounding box will
+%   be constant, so the \texttt{save} function should only be called once. Thus
+%   a typical use case is
+%   \begin{verbatim}
+%   \graphics_bb_restore:nF { <name> }
+%     {
+%       % Code to read the bb
+%       \graphics_bb_save:n { <name> }
+%     }
+%   \end{verbatim}
+%   \emph{i.e.}~every use of a bounding box will attempt to restore saved data,
+%   and saving will only take place where that is not possible.
+%   
+%   Note that the \meta{graphic} may not be a simple file name: a multi-page PDF,
+%   for example, will need to have the bounding box cached for each page used.
+% \end{function}
+%
+% \begin{function}{\graphics_extract_bb:n}
+%   \begin{syntax}
+%     \cs{graphics_extract_bb:n} \Arg{file}
+%   \end{syntax}
+%   Extracts bounding box data for the graphic \meta{file} using the |extractbb|
+%   utility, and stores the bounding box of the graphic file in
+%   \cs{l_graphics_llx_dim}, \cs{l_graphics_lly_dim}, \cs{l_graphics_urx_dim} and
+%   \cs{l_graphics_ury_dim}.
+%
+%   The \meta{file} name should be fully-qualified and sanitized: no search
+%   or other manipulation is carried out at this level. No check is made on
+%   the file \emph{type} at this stage: it is assumed that the driver code
+%   using this function has made such a check. File types such as |.pdf| and
+%   |.jpg| are appropriate for parsing using this function.
+%
+%   When \cs{l_graphics_page_int} is positive the appropriate page will be
+%   queried from the graphic file.
+%
+%   Note that this function requires pipe shell calls to be enabled: this is
+%   generally true but may require the option |--enable-pipes| to be enabled
+%   when running the \TeX{} job.
+% \end{function}
+%
+% \begin{function}{\graphics_read_bb:n}
+%   \begin{syntax}
+%     \cs{graphics_read_bb:n} \Arg{file}
+%   \end{syntax}
+%   Parses the graphic \meta{file} to find a PostScript-style bounding box
+%   line of the form
+%   \begin{verbatim}
+%   %%BoundingBox: llx lly urx urx
+%   \end{verbatim}
+%   where \meta{llx}, \meta{lly}, \meta{urx} and \meta{ury} are the corners
+%   of the bounding box expressed in PostScript (\enquote{big}) points. The
+%   values are stored in \cs{l_graphics_llx_dim}, \cs{l_graphics_lly_dim},
+%   \cs{l_graphics_urx_dim} and \cs{l_graphics_ury_dim}.
+%
+%   The \meta{file} name should be fully-qualified and sanitized: no search
