+%
+% \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
+% 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 |.eps| and
+% |.bb|/|.xbb| are appropriate for parsing using this function.
+% \end{function}
+%
+% \begin{function}{\graphics_include:n, \graphics_include:nn}
+% \begin{syntax}
+% \cs{graphics_include:n} \Arg{file}
+% \cs{graphics_include:nn} \Arg{file} \Arg{type}
+% \end{syntax}
+% Horizontal-mode commands which include the \meta{file} as an graphic
+% at the current location. The file \meta{type} is given explicitly in
+% the two-argument version, or is inferred from the file extension extracted
+% in the single-argument form. The exact graphic types supported depend upon
+% the driver in use.
+%
+% Where the \meta{file} is not found and the \meta{type} is \emph{not}
+% given, a search for possible graphic files is undertaken using the extensions
+% stored in \cs{l_graphics_search_ext_seq}.
+% \end{function}
+%
+% \begin{variable}{\l_graphics_ext_type_prop}
+% Defines mapping between file extensions and file types; where there is
+% no entry for an extension, the type is assumed to be the extension
+% with the leading |.| removed. Entries should be made in lower case, and
+% the key should be an extension including the leading |.|, for example
+% \begin{verbatim}
+% \prop_put:Nnn \l_graphics_ext_type_prop { .ps } { eps }
+% \end{verbatim}
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_search_ext_seq}
+% Extensions to use for graphic searching when the given \meta{file} name is not
+% found by \cs{graphics_include:n}.
+% \end{variable}
+%
+% \begin{variable}{\l_graphics_search_path_seq}
+% Each entry is the path to a directory which should be searched when
+% seeking an graphic file. Each path can be relative or absolute, and should
+% not include the trailing slash. The entries are not expanded when
+% used so may contain active characters but should not feature any
+% variable content. Spaces need not be quoted.
+% \end{variable}
+%
+% \begin{function}{\graphics_show_list:, \graphics_log_list:}
+% \begin{syntax}
+% \cs{graphics_show_list:}
+% \cs{graphics_log_list:}
+% \end{syntax}
+% These functions list all graphic files loaded by in a similar manner to
+% \cs{file_show_list:} and \cs{file_log_list:}. While
+% \cs{graphics_show_list:} displays the list in the terminal,
+% \cs{graphics_log_list:} outputs it to the log file only. In both cases, only
+% graphics loaded by \pkg{l3graphics} are listed.

+% Extracting the bounding box from an |.eps| or |.bb| file is done by
+% reading each line and searching for the marker text |%%BoundingBox:|.
+% The data is read as a string with a mapping over
+% the lines: as there is a colon involved, a little bit of work is needed to
+% get the matching correct. The same approach covers cases where the bounding
+% box has to be calculated by |extractbb|, with just the initial phase

+% Before any real searching, a check to see if there are cached values
+% available. The name of each graphic will be unique and so it's sensible to
+% store the bounding box data in \TeX{}: this avoids multiple file operations.
+% As bounding boxes here start away from the lower-left origin, we need to
+% store all four values (contrast with for example the \texttt{pdfmode}
+% driver). Here |#2| is a potential page identifier: used to allow caching of
+% individual pages in a multi-page document. Caching is applied to the
+% upper-right position in all cases, but as the lower-left will often be
+% $(0,0)$ it is only cached if required.

+% If the bounding box is |atend|, just ignore the current one and keep going.
+% Otherwise, we need to allow for tabs and multiple spaces (as the line has

+% tokens: at this stage the line fragment should be just numbers and
+% whitespace. \TeX{} will then tidy up for us, with just a leading space to
+% worry about: that is taken out by the |\use:n| here.
