+LaTeX3 Backend Drivers
+======================
+
+Release 2019-07-01
+
+This package forms parts of `expl3`, and contains the code used to interface
+with backends (drivers) across the `expl3` codebase. The functions here are
+defined differently depending on the engine in use. As such, these are
+distributed separately from `l3kernel` to allow this code to be updated
+on an independent schedule.

+% \end{macrocode}
+%
+% Whilst there is a reasonable amount of code overlap between backends,
+% it is much clearer to have the blocks more-or-less separated than run
+% in together and DocStripped out in parts. As such, most of the following
+% is set up on a per-backed basis, though there is some common code (again
+% given in blocks not interspersed with other material).
+%
+% All the file identifiers are up-front so that they come out in the right
+% place in the files.
+% \begin{macrocode}
+%<*package>

+% \end{macrocode}
+%
+% The order of the backend code here is such that we get somewhat logical
+% outcomes in terms of code sharing whilst keeping things readable. (Trying to
+% mix all of the code by concept is almost unmanageable.) The key parts which
+% are shared are
+% \begin{itemize}
+% \item Color support is either \texttt{dvips}-like or \texttt{pdfmode}-like.
+% \item \texttt{pdfmode} and \texttt{(x)dvipdfmx} share drawing routines.
+% \item \texttt{xdvipdfmx} is largely the same as \texttt{dvipdfmx} so
+% takes most of the same code.
+% \end{itemize}
+%
+% \begin{macro}
+% {
+% \__kernel_backend_literal:e,
+% \__kernel_backend_literal:n,
+% \__kernel_backend_literal:x
+% }
+% The one shared function for all backends is access to the basic
+% \tn{special} primitive: it has slightly odd expansion behaviour
+% so a wrapper is provided.
+% \begin{macrocode}
+\cs_new_eq:NN \__kernel_backend_literal:e \tex_special:D
+\cs_new_protected:Npn \__kernel_backend_literal:n #1
+ { \__kernel_backend_literal:e { \exp_not:n {#1} } }
+\cs_generate_variant:Nn \__kernel_backend_literal:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{\texttt{dvips} backend}
+%
+% \begin{macrocode}
+%<*dvips>
+% \end{macrocode}
+%
+% \begin{macro}
+% {\__kernel_backend_literal_postscript:n, \__kernel_backend_literal_postscript:x}
+% Literal PostScript can be included using a few low-level formats. Here,
+% we use the form with no positioning: this is overall more convenient as
+% a wrapper. Note that this does require that where position is important,
+% an appropriate wrapper is included.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_literal_postscript:n #1
+ { \__kernel_backend_literal:n { ps:: #1 } }
+\cs_generate_variant:Nn \__kernel_backend_literal_postscript:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_postscript:n, \__kernel_backend_postscript:x}
+% PostScript data that does have positioning, and also applying
+% a shift to |SDict| (which is not done automatically by
+% |ps:| or |ps::|, in contrast to |!| or |"|).
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_postscript:n #1
+ { \__kernel_backend_literal:n { ps: SDict ~ begin ~ #1 ~ end } }
+\cs_generate_variant:Nn \__kernel_backend_postscript:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_postscript_header:n}
+% PostScript for the header: a small saving but makes the code clearer.
+% This is held until the start of shipout such that a document with no
+% actual output does not write anything.
+% \begin{macrocode}
+\cs_new_protected:Npx \__kernel_backend_postscript_header:n #1
+%<*initex>
+ { \__kernel_backend_literal:n { ! #1 } }
+%</initex>
+%<*package>
+ {
+ \cs_if_exist:NTF \AtBeginDvi
+ { \exp_not:N \AtBeginDvi }
+ { \use:n }
+ { \__kernel_backend_literal:n { ! #1 } }
+ }
+%</package>
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}
+% {
+% \__kernel_backend_align_begin:,
+% \__kernel_backend_align_end:
+% }
+% In \texttt{dvips} there is no build-in saving of the current
+% position, and so some additional PostScript is required to set up the
+% transformation matrix and also to restore it afterwards. Notice the use
+% of the stack to save the current position \enquote{up front} and to
+% move back to it at the end of the process. Notice that the |[begin]|/^^A
+% |[end]| pair here mean that we can use a run of PostScript statements
+% in separate lines: not \emph{required} but does make the code and
+% output more clear.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_align_begin:
+ {
+ \__kernel_backend_literal:n { ps::[begin] }
+ \__kernel_backend_literal_postscript:n { currentpoint }
+ \__kernel_backend_literal_postscript:n { currentpoint~translate }
+ }
+\cs_new_protected:Npn \__kernel_backend_align_end:
+ {
+ \__kernel_backend_literal_postscript:n { neg~exch~neg~exch~translate }
+ \__kernel_backend_literal:n { ps::[end] }
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_scope_begin:, \__kernel_backend_scope_end:}
+% Saving/restoring scope for general operations needs to be done with
+% \texttt{dvips} positioning (try without to see this!). Thus we need the
+% |ps:| version of the special here. As only the graphics state is ever
+% altered within this pairing, we use the lower-cost |g|-versions.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_scope_begin:
+ { \__kernel_backend_literal:n { ps:gsave } }
+\cs_new_protected:Npn \__kernel_backend_scope_end:
+ { \__kernel_backend_literal:n { ps:grestore } }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macrocode}
+%</dvips>
+% \end{macrocode}
+%
+% \subsection{\texttt{pdfmode} backend}
+%
+% \begin{macrocode}
+%<*pdfmode>
+% \end{macrocode}
+%
+% The direct PDF backend covers both \pdfTeX{} and \LuaTeX{}. The latter
+% renames and restructures the backend primitives but this can be handled
+% at one level of abstraction. As such, we avoid using two separate backends
+% for this material at the cost of some \texttt{x}-type definitions to get
+% everything expanded up-front.
+%
+% \begin{macro}{\__kernel_backend_literal_pdf:n, \__kernel_backend_literal_pdf:x}
+% This is equivalent to \verb|\special{pdf:}| but the engine can
+% track it. Without the \texttt{direct} keyword everything is kept in
+% sync: the transformation matrix is set to the current point automatically.
+% Note that this is still inside the text (\texttt{BT} \dots \texttt{ET}
+% block).
+% \begin{macrocode}
+\cs_new_protected:Npx \__kernel_backend_literal_pdf:n #1
+ {
+ \cs_if_exist:NTF \tex_pdfextension:D
+ { \tex_pdfextension:D literal }
+ { \tex_pdfliteral:D }
+ { \exp_not:N \exp_not:n {#1} }
+ }
+\cs_generate_variant:Nn \__kernel_backend_literal_pdf:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_literal_page:n}
+% Page literals are pretty simple. To avoid an expansion, we write out
+% by hand.
+% \begin{macrocode}
+\cs_new_protected:Npx \__kernel_backend_literal_page:n #1
+ {
+ \cs_if_exist:NTF \tex_pdfextension:D
+ { \tex_pdfextension:D literal ~ }
+ { \tex_pdfliteral:D }
+ page
+ { \exp_not:N \exp_not:n {#1} }
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_scope_begin:, \__kernel_backend_scope_end:}
+% Higher-level interfaces for saving and restoring the graphic state.
+% \begin{macrocode}
+\cs_new_protected:Npx \__kernel_backend_scope_begin:
+ {
+ \cs_if_exist:NTF \tex_pdfextension:D
+ { \tex_pdfextension:D save \scan_stop: }
+ { \tex_pdfsave:D }
+ }
+\cs_new_protected:Npx \__kernel_backend_scope_end:
+ {
+ \cs_if_exist:NTF \tex_pdfextension:D
+ { \tex_pdfextension:D restore \scan_stop: }
+ { \tex_pdfrestore:D }
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_matrix:n, \__kernel_backend_matrix:x}
+% Here the appropriate function is set up to insert an affine matrix
+% into the PDF. With \pdfTeX{} and \LuaTeX{} in direct PDF output mode there
+% is a primitive for this, which only needs the rotation/scaling/skew part.
+% \begin{macrocode}
+\cs_new_protected:Npx \__kernel_backend_matrix:n #1
+ {
+ \cs_if_exist:NTF \tex_pdfextension:D
+ { \tex_pdfextension:D setmatrix }
+ { \tex_pdfsetmatrix:D }
+ { \exp_not:N \exp_not:n {#1} }
+ }
+\cs_generate_variant:Nn \__kernel_backend_matrix:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macrocode}
+%</pdfmode>
+% \end{macrocode}
+%
+% \subsection{\texttt{dvipdfmx} backend}
+%
+% \begin{macrocode}
+%<*dvipdfmx|xdvipdfmx>
+% \end{macrocode}
+%
+% The \texttt{dvipdfmx} shares code with the PDF mode one (using the common
+% section to this file) but also with \texttt{xdvipdfmx}. The latter is close
+% to identical to \texttt{dvipdfmx} and so all of the code here is extracted
+% for both backends, with some \texttt{clean up} for \texttt{xdvipdfmx} as
+% required.
+%
+% \begin{macro}{\__kernel_backend_literal_pdf:n, \__kernel_backend_literal_pdf:x}
+% Equivalent to \texttt{pdf:content} but favored as the link to
+% the \pdfTeX{} primitive approach is clearer.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_literal_pdf:n #1
+ { \__kernel_backend_literal:n { pdf:literal~ #1 } }
+\cs_generate_variant:Nn \__kernel_backend_literal_pdf:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_literal_page:n}
+% Whilst the manual says this is like |literal direct| in \pdfTeX{},
+% it closes the |BT| block!
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_literal_page:n #1
+ { \__kernel_backend_literal:n { pdf:literal~direct~ #1 } }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_scope_begin:, \__kernel_backend_scope_end:}
+% Scoping is done using the backend-specific specials.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_scope_begin:
+ { \__kernel_backend_literal:n { x:gsave } }
+\cs_new_protected:Npn \__kernel_backend_scope_end:
+ { \__kernel_backend_literal:n { x:grestore } }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macrocode}
+%</dvipdfmx|xdvipdfmx>
+% \end{macrocode}
+%
+% \subsection{\texttt{dvisvgm} backend}
+%
+% \begin{macrocode}
+%<*dvisvgm>
+% \end{macrocode}
+%
+% \begin{macro}{\__kernel_backend_literal_svg:n, \__kernel_backend_literal_svg:x}
+% Unlike the other backends, the requirements for making SVG files mean
+% that we can't conveniently transform all operations to the current point.
+% That makes life a bit more tricky later as that needs to be accounted for.
+% A new line is added after each call to help to keep the output readable
+% for debugging.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_literal_svg:n #1
+ { \__kernel_backend_literal:n { dvisvgm:raw~ #1 { ?nl } } }
+\cs_generate_variant:Nn \__kernel_backend_literal_svg:n { x }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_scope_begin:, \__kernel_backend_scope_end:}
+% A scope in SVG terms is slightly different to the other backends as
+% operations have to be \enquote{tied} to these not simply inside them.
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_scope_begin:
+ { \__kernel_backend_literal_svg:n { <g> } }
+\cs_new_protected:Npn \__kernel_backend_scope_end:
+ { \__kernel_backend_literal_svg:n { </g> } }
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\__kernel_backend_scope_begin:n, \__kernel_backend_scope_begin:x}
+% In SVG transformations, clips and so on are attached directly to scopes so
+% we need a way or allowing for that. This is rather more useful than
+% \cs{__kernel_backend_scope_begin:} as a result.
+% No assumptions are made about the nature
+% of the scoped operation(s).
+% \begin{macrocode}
+\cs_new_protected:Npn \__kernel_backend_scope_begin:n #1
+ { \__kernel_backend_literal_svg:n { <g~ #1 > } }
+\cs_generate_variant:Nn \__kernel_backend_scope_begin:n { x }

+% \begin{macro}{\@@_backend_clip:N}
+% The \texttt{dvips} backend scales all absolute dimensions based on the
+% output resolution selected and any \TeX{} magnification. Thus for any
+% operation involving absolute lengths there is a correction to make. See
+% \texttt{normalscale} from \texttt{special.pro} for the variables, noting
+% that here everything is saved on the stack rather than as a separate
+% variable. Once all of that is done, the actual clipping is trivial.

+%
+% \begin{macro}{\@@_backend_clip:N}
+% The general method is to save the current location, define a clipping path
+% equivalent to the bounding box, then insert the content at the current
+% position and in a zero width box. The \enquote{real} width is then made up
+% using a horizontal skip before tidying up. There are other approaches that
+% can be taken (for example using XForm objects), but the logic here shares
+% as much code as possible and uses the same conversions (and so same
+% rounding errors) in all cases.

+% Rotations are set using an affine transformation matrix which therefore
+% requires sine/cosine values not the angle itself. We store the rounded
+% values to avoid rounding twice. There are also a couple of comparisons to
+% ensure that |-0| is not written to the output, as this avoids any issues
+% with problematic display programs. Note that numbers are compared to~$0$
+% after rounding.

+% \begin{macro}{\@@_backend_rotate_aux:Nn}
+% Rotating in \texttt{(x)}dvipdmfx can be implemented using either PDF or
+% backend-specific code. The former approach however is not \enquote{aware}
+% of the content of boxes: this means that any embedded links would not be
+% adjusted by the rotation. As such, the backend-native approach is preferred:
+% the code therefore is similar (though not identical) to the \texttt{dvips}
+% version (notice the rotation angle here is positive). As for
+% \texttt{dvips}, zero rotation is written as |0| not |-0|.

+%
+% \begin{macro}{\@@_backend_clip:N}
+% \begin{variable}{\g_@@_clip_path_int}
+% Clipping in SVG is more involved than with other backends. The first issue
+% is that the clipping path must be defined separately from where it is used,
+% so we need to track how many paths have applied. The naming here uses
+% \texttt{l3cp} as the namespace with a number following. Rather than use
+% a rectangular operation, we define the path manually as this allows it to
+% have a depth: easier than the alternative approach of shifting content
+% up and down using scopes to allow for the depth of the \TeX{} box and
+% keep the reference point the same!
+% \begin{macrocode}
+\cs_new_protected:Npn \@@_backend_clip:N #1

+ \int_gincr:N \g_@@_clip_path_int

+ \__kernel_backend_literal_svg:n
+ { < /clipPath > }
+% \end{macrocode}
+% In general the SVG set up does not try to transform coordinates to the
+% current point. For clipping we need to do that, so have a transformation
+% here to get us to the right place, and a matching one just before the
+% \TeX{} box is inserted to get things back on track. The clip path needs to
+% come between those two such that if lines up with the current point, as
+% does the \TeX{} box.

+% Color support is split into two parts: a \enquote{general} concept and
+% one directly linked to drawings (or rather the split between filling
+% and stroking). General color is relatively easy to handle: we have a color
+% stack available with all modern drivers, and can use that.
+% Whilst \texttt{(x)dvipdfmx} does have its own approach to color specials,
+% it is easier to use \texttt{dvips}-like ones for all cases except direct
+% PDF output.

+% The |ps::[begin]| special here deals with positioning but allows us to

+% but where we can't split material between separate calls. The
+% |@beginspecial|/|@endspecial| pair are from |special.pro| and correct the
+% scale and $y$-axis direction. The definition of |/color.fc| deals with fill
+% color in paths. In contrast to \pkg{pgf}, we don't save the current point:
+% discussion with Tom Rokici suggested a better way to handle the necessary
+% translations (see \cs{@@_backend_box_use:Nnnnn}). (Note that
+% |@beginspecial|/|@endspecial| forms a backend scope.) The |[begin]|/^^A
+% |[end]| lines are handled differently from the rest as they are
+% conceptually different: not really drawing literals but instructions to
+% \texttt{dvips} itself.

+% Unlike PDF, PostScript doesn't track separate colors for strokes and other

+% \begin{macro}{\@@_backend_cm:nnnn}
+% In \texttt{dvips}, keeping the transformations in line with the engine

+% tracking (\emph{cf.}~\texttt{(x)dvipdfmx}). Thus we take the shortest
+% path available and simply dump the matrix as given.

+% \begin{macro}{\@@_backend_box_use:Nnnnn}
+% Inside a picture |@beginspecial|/|@endspecial| are active, which is
+% normally a good thing but means that the position and scaling would be off
+% if the box was inserted directly. To deal with that, there are a number of
+% possible approaches. The implementation here was suggested by Tom Rokici
+% (author of \texttt{dvips}). We end the current special placement, then
+% set the current point with a literal |[begin]|. As for general
+% literals, we then use the stack to store the current point and move to
+% it. To insert the required transformation, we have to flip the $y$-axis,
+% once before and once after it. Then we get back to the \TeX{} reference
+% point to insert our content. The clean up has to happen in the right
+% places, hence the |[begin]|/|[end]| pair around |restore|. Finally,
+% we can return to \enquote{normal} drawing mode. Notice that the set up
+% here is very similar to that in \cs{@@_align_currentpoint_\ldots}, but
+% the ordering of saving and restoring is different (intermixed).

+% Internally, transformations for drawing are tracked as a matrix. Not all
+% engines provide a way of dealing with this: if we use a raw matrix, the
+% engine looses track of positions (for example for hyperlinks), and this is
+% not desirable. They do, however, allow us to track rotations and scalings.
+% Luckily, we can decompose any (two-dimensional) matrix into two rotations
+% and a single scaling:
+% \[
+% \begin{bmatrix}
+% A & B \\ C & D
+% \end{bmatrix}
+% =
+% \begin{bmatrix}
+% \cos\beta & \sin\beta \\ -\sin\beta & \cos\beta
+% \end{bmatrix}
+% \begin{bmatrix}
+% w_{1} & 0 \\ 0 & w_{2}
+% \end{bmatrix}
+% \begin{bmatrix}
+% \cos\gamma & \sin\gamma \\ -\sin\gamma & \cos\gamma
+% \end{bmatrix}
+% \]
+% The parent matrix can be converted to
+% \[
+% \begin{bmatrix}
+% A & B \\ C & D
+% \end{bmatrix}
+% =
+% \begin{bmatrix}
+% E & H \\-H & E
+% \end{bmatrix}
+% +
+% \begin{bmatrix}
+% F & G \\ G & -F
+% \end{bmatrix}
+% \]
+% From these, we can find that
+% \begin{align*}
+% \frac{w_{1} + w_{2}}{2} &= \sqrt{E^{2} + H^{2}} \\
+% \frac{w_{1} - w_{2}}{2} &= \sqrt{F^{2} + G^{2}} \\
+% \gamma - \beta &= \tan^{-1}(G/F) \\
+% \gamma + \beta &= \tan^{-1}(H/E)
+% \end{align*}
+% at which point we just have to do various pieces of re-arrangement to
+% get all of the values. (See J.~Blinn, \emph{IEEE Comput.\ Graph.\ Appl.},
+% 1996, \textbf{16}, 82--88.) There is one wrinkle: the PostScript (and PDF)
+% way of specifying a transformation matrix exchanges where one would
+% normally expect $B$ and $C$ to be.

+% Links are crated like annotations but with dedicated code to allow for
+% adjusting the size of the rectangle. In contrast to \pkg{hyperref}, we
+% grab the link content as a box which can then unbox: this allows the same
+% interface as for \pdfTeX{}.
+%
+% Taking the idea of |evenboxes| from \pkg{hypdvips}, we implement a minimum
+% box height and depth for link placement. This means that \enquote{underlining}
+% with a hyperlink will generally give an even appearance. However, to ensure
+% that the full content is always above the link border, we do not allow
+% this to be negative (contrast \pkg{hypdvips} approach). The result should
+% be similar to \pdfTeX{} in the vast majority of foreseeable cases.
+%
+% The object number for a link is saved separately from the rest of the
+% dictionary as this allows us to insert it just once, at either an
+% unbroken link or only in the first line of a broken one. That makes the
+% code clearer but also avoids a low-level PostScript error with the code
+% as taken from \pkg{hypdvips}.
+%
+% Getting the outer dimensions of the text area may be better using a two-pass
+% approach and |\tex_savepos:D|. That plus format mode are still to re-examine.
