% \section{Changing the font series}
%
% In the original NFSS implementation the series was a single
% attribute stored in \cs{f@series} and so one always had to specify
% both weight and width together. This meant that it was impossible to
% typeset a paragraph in a condensed font and inside have a few words
% in bold weight (but still condensed) without doing this manually by
% requesting \verb=\fontseries{bc}\selectfont=.
%
% The new implementation now works differently, by looking at both the
% current value of \cs{f@series} and the requested new series; these
% are then used to select a new series value. Thus, if the
% current series is \texttt{c} and we ask for \texttt{b} we now get
% \texttt{bc}.
%
% This is done by consulting a simple lookup table. This table is
% configurable (though most likely that flexibility will seldom if
% ever be needed). Adding or changing entries in this table is done
% with \cs{DeclareFontSeriesChangeRule}.
%
% \subsection{The series lookup table}
%
%
%  \begin{macro}{\DeclareFontSeriesChangeRule}
%    The macro \cs{DeclareFontSeriesChangeRule} defines entries in a simple
%    database (implemented as a set of commands) that define mappings
%    from the current series and a requested new series to a result series
%    (and additionally offers an alternative if the desired one is 
%    unavailable):
%    \begin{itemize}
%    \item[\texttt{\#1}] current \cs{f@series}
%    \item[\texttt{\#2}] requested new series
%    \item[\texttt{\#3}] result (provided this series exists in the given font family)
%    \item[\texttt{\#4}] alternative result (if \texttt{\#3} does not exist)
%    \end{itemize}
%    If an \texttt{.fd} file has its own substitution rules then
%    \texttt{\#3} exist and thus \texttt{\#4} is not applied.
%
%    If there is no matching database entry, or if neither the result
%    nor the alternative result exists in this font family, then the requested
%    new series is used (which then may trigger substitutions later on).
%    \begin{macrocode}
\def\DeclareFontSeriesChangeRule#1#2#3#4{%
  \@namedef{series@#1@#2}{{#3}{#4}}}
%    \end{macrocode}
%  \end{macro}
%
% \subsection{Mapping rules for series changes}
%
% The rules set up use explicit series values not \cs{..default}
% indirections; my current feeling is that this is in fact better.
%
% With 9~weight values (from \texttt{ul} to \texttt{ub}) and 9~width values
% (from \texttt{uc} to \texttt{ux}), this table is now rather large
% (far more than 1000~entries), but, on the other hand, the table
% doesn't change and accessing rules is fast when using a table implemented
% in this way.
%
% We could alternatively split the axis and maintain weight and width
% separately, but that would take more processing time and would not
% allow for setting up explicit exceptions nicely (not sure that this
% would ever get used though).
%
% Design considerations for mapping entries:
% \begin{itemize}
% \item
%
%    We make \texttt{m} reset both weight and width (as this is
%    how it always worked). To reset just the width \texttt{?m} is
%    provided and to reset just the weight \texttt{m?}\ is provided.
%
% \item
%
%    We support ``\texttt{m}\meta{width}'' and
%    ``\meta{weight}\texttt{m}'', e.g., \texttt{mec} to mean ``go to
%    medium weight and extra-condensed width''. At the end of the
%    process we automatically drop any leftover \texttt{m} in the
%    series name (unless it is just a single \texttt{m}).
%
% \item
%
%    If there is no table entry then the requested series is used
%    unconditionally. This means that we usually do not need entries
%    where the second argument (the requested series) and the third argument
%    (the result series) are identical (unless we want to use the fourth
%    argument to specify an alternative result series). In particular,
%    this means:
%    \begin{itemize}
%    \item
%
%      Any request for \texttt{m} needs no entry, i.e., there are no entries
%      which have \texttt{m} as the second argument.
%
%    \item
%
%       Any request to set both weight and width (e.g., \texttt{sbx} or
%       \texttt{ulc}) needs no entry. For that reason, there are no entries
%       which have a weight+width as second argument (except for cases
%       involving \texttt{bx}, see below). In particular, this is also true
%       for cases involving \texttt{m}, e.g., \texttt{bm} (bold medium width)
%       which automatically gets reduced to \texttt{b}, or \texttt{mc}
%      (medium weight condensed) which becomes \texttt{c} as a result.
%
%       There is one exception: we do have rules for a request for
%       \texttt{bx}; this is because the Computer Modern fonts (or related
%       families like Latin Modern) need \texttt{bx} as their bold series
%       default (\cs{bfdefault}),
%       since they only have a \texttt{b} series for a
%       restricted set of font faces. Many other font families have only
%       \texttt{b} but no \texttt{bx}, so we have explicit rules
%       that fall back from \texttt{bx} to \texttt{b}.
%    \end{itemize}
%
% \item
%
%    For each combination of a non-\texttt{m} \meta{weight} and a
%    non-\texttt{m} \meta{width}, there are 19~entries which have
%    ``\meta{weight}\meta{width}'' as first argument: 8~of them have
%    the weight values from \texttt{ul} to \texttt{ub} except \texttt{m} as
%    second argument, another 8~have the width values from \texttt{uc}
%    to \texttt{ux} except \texttt{m} as second argument, and (further down
%    in this file) there is one entry which has \texttt{bx} as second
%    argument and two further entries which have \texttt{m?}\ and
%    \texttt{?m} as second argument. Rules which have \texttt{m} or a
%    weight+width (other than \texttt{bx}) as second argument aren't needed
%    (see above).
%
% \item
%
%    For each non-\texttt{m} \meta{weight}, there are at least 11~entries
%    which have ``\meta{weight}'' as first argument: 8~of them have the
%    width values from \texttt{uc} to \texttt{ux} except \texttt{m} as
%    second argument, and (further down in this file) there is one entry
%    which has \texttt{bx} as second argument and two further entries
%    which have \texttt{m?}\ and \texttt{?m} as second argument. Rules
%    which have a single weight value as second argument aren't needed
%    because the second and third arguments would then be identical. In
%    some cases, there are extra rules which make use of the fourth
%    argument to specify an alternative result series.
%
% \item
%
%    Similarily, for each non-\texttt{m} \meta{width}, there are at least
%    11~entries which have ``\meta{width}'' as first argument: 8~of them
%    have the weight values from \texttt{ul} to \texttt{ub} except
%    \texttt{m} as second argument, and (further down in this file) there
%    is one entry which has \texttt{bx} as second argument and two
%    further entries which have \texttt{m?}\ and \texttt{?m} as second
%    argument. Rules which have a single width value as second argument
%    aren't needed because the second and third arguments would then be
%    identical. In some cases, there are extra rules which make use of the
%    fourth argument to specify an alternative result series.
%
% \item
%
%    Only a few entries have ``alternative'' values.
%
%    The idea is that you don't want the normal substitution to kick
%    in because that would reset the shape first and it may be better
%    to stay with \texttt{b} when a change to \texttt{c} is requested
%    and \texttt{bc} doesn't exist, than to go to first change the
%    shape to \texttt{n} and then find that \texttt{bc/n} doesn't
%    exist either and thus ending up with \texttt{m/n}.
%
%    We do this, for example, when \texttt{sb}, \texttt{eb}, or
%    \texttt{ub} is requested but can't be fulfilled. In that case it
%    is better to try to stay with some sort of bold rather than
%    ending up with \texttt{m}. There are some other cases where an
%    ``alternative'' value is specified; these are explained below in
%    the appropriate places.

%    This special rule normally does nothing since nearly every font
%    implements the \texttt{b} bold series. The exception are Computer
%    Modern and Latin Modern and fonts based on them. They usually
%    only have \texttt{bx}, but then they normally provide an
%    \texttt{.fd} file declaration mapping from \texttt{b} to
%    \texttt{bx} and thus pretend that \texttt{b} exists. But in case
%    any of them does not, we offer an alternative result and switch
%    to \texttt{bx} if \texttt{b} can't be found.

%    Here are the special rules for \texttt{m?}. We offer \texttt{m} as
%    alternative result series for all entries where this is not already the
%    result series, because otherwise, if the result series does not exist,
%    \texttt{m?}\ would be tried as the series value, which cannot work. (Of
%    course, this does not help if the \texttt{m} series does not exist
%    either, but this should only affect very few fonts.)

%  \begin{macro}{\fontseries}
%    The \cs{fontseries} command takes one argument which is the requested new
%    font series. In the original implementation it simply saved the
%    expanded value in \cs{f@series}. Now we do a bit more processing

%
%    There is kind of the same problem with returning back from
%    \texttt{sc} to normal. It sort of needs its own letter.  In
%    \texttt{fontspec} this was solved by the first time \cs{upshape} changes
%    \texttt{it} or \texttt{sl} back (so only \texttt{sc} remains) and
%    second time it changes then \texttt{sc} back to normal.  Maybe
%    that's not a bad way to handle it, but decided for a slightly
%    different approach: \texttt{n} always returns to ``normal'', ie
%    resets everything and \texttt{up} changes italic or slanted to
%    upright and \texttt{ulc} undoes small caps.
%
%    So we now offer \cs{normalshape} (using \cs{shapedefault}) which

%    The next rule might be a bit surprising, and rightly so.
%    It would be more correct if \texttt{sc}
%    were not affected by \texttt{up}, so that it
%    remains \texttt{sc} as shown in the commented out rule. However,
%    for nearly three decades commands such as \cs{upshape} or
%    \cs{textup} changed small caps back to the ``normal'' shape. So
%    for backward compatibility we keep that behavior.
%
%    As a result you are currently typesetting in \texttt{scit} or
%    \texttt{scsl} using \cs{upshape} twice will return you to the
%    normal shape too, the first will change to \texttt{sc} and the
%    second (because of the rule below) change that to
%    \texttt{n}. This is the way \texttt{fontspec} implemented its
%    version on this interface, so this rule means we are also
%    compatible with the way \texttt{fontspec} behaved. Still it
%    remains an oddity which I would rather liked to have avoided.

%    The next rule assumes that if \texttt{scit} exists then
%    \texttt{it} exists as well. If not, the mechanism will save
%    \texttt{ulc} in \cs{f@series}, which most certainly doesn't
%    exist. So when a font is later selected that would result in a
%    substitution (so no harm done really). Alternatively, we could in
%    this case use \texttt{n} as alternative, which may be a bit
%    faster, but such a  setup would be so weird in the first place

% \section{Make sure we win \ldots}
%
%    This code implements one aspect of what the package \textsf{fontaxes}
%    provide. So its redefinitions for the various shape commands,
%    such as \cs{itshape} should no longer happen. We therefore force
%    the standard definitions at \cs{AtBeginDocument} (later when this
%    is defined). Once
%    \texttt{fontaxes} is no longer doing such redefinitions that could
%    be taken out again.
%
%    We use a separate macro so that we can easily disable this (in
%    case of rollback).
