%    These packages provides fixes to \LaTeXe{} which are desirable
%    but cannot be integrated into the \LaTeXe{} kernel or the 
%    font definition files directly as they would produce a version 
%    incompatible to earlier releases (either in formatting or 
%    functionality).
%
%    By providing these fixes in the form of packages, users can benefit
%    from them without the danger that their documents will fail or
%    produce unexpected results at other sites since the documents
%    contain a clear indication (the |\usepackage| line, preferably
%    with a required date) that the fixes are needed.

% \section{Introduction}
%
% In the newsletter \texttt{ltnews07.tex}, which accompanied the
% \LaTeXe{} maintenance release of June 1997, we wrote:
% \begin{quote}
%    Many of the problem reports we receive concerning the standard
%    classes are not concerned with bugs but are suggesting, more or
%    less politely, that the design decisions embodied in them are
%    `not optimal' and asking us to modify them.
%    
%    There are several reasons why we have decided not to make such
%    changes to these files.
%    \begin{itemize}
%    \item However misguided, the current behaviour is clearly what
%    was intended when these classes were designed.  \item It is not
%    good practice to change such aspects of `standard classes'
%    because many people will be relying on them.
%    \end{itemize}
%    
%    We have therefore decided not to even consider making such
%    modifications, nor to spend time justifying that decision.  This
%    does not mean that we do not agree that there are many
%    deficiencies in the design of these classes, but we have many
%    tasks with higher priority than continually explaining why the
%    standard classes for \LaTeX{} cannot be changed.
% \end{quote}
%
% Back then we probably should have said that this decision also
% covers changes to the \LaTeX{} kernel and font definitions,
% if the change results in
% noticeable differences in the formatting of documents or otherwise
% produces severe incompatibilities between releases. The important
% point to stress here is that ``people rely on the fact that a
% document formatted at one site produces identical output at a
% different site''. By fixing a certain problem in version
% \meta{date}, people making use of the fix will get incorrectly
% formatted documents if they send them to others who still run on a
% version prior to \meta{date}.
%
% In theory one could get around this by adding a line like
% \begin{quote}
% |\NeedsTeXFormat{latex2e}[|\meta{date}|]| 
% \end{quote}
% on top of the document. However, this fails for two reasons. Firstly,
% most people will not be aware that they make use of a feature or fix
% that is only available in their version of \LaTeX{}; and thus do not
% add such a line in their documents. Secondly, even if there is such a
% line the receiving site might not be able to upgrade their \LaTeX{}
% in time to process the document properly (the latter is a sad fact
% of life).
%
% By providing the \Lpack{fixltx2e} and \Lpack{fix-cm} packages 
% we hope to help people in this respect since, when they
% are used, a document will contain a clear
% indication that special features/fixes are needed and if the
% receiving site does not have the packages available (or not available
% with the right version) it is far easier to download and install them
% from some archive than to upgrade \LaTeX{} in a rush.
%
% The packages are independent from each other and deal with different 
% subjects:
% \Lpack{fixltx2e} provides general changes to the \LaTeX{} kernel,
% while \Lpack{fix-cm} improves the definitions of the Computer Modern 
% font families.
%
% We will try to maintain the packages in such a way that they can be used
% with all maintenance releases of \LaTeXe{} so that, if urgently
% needed, people can simply add them to the current directory in case
% they cannot upgrade their \LaTeX{} for whatever reason.
%
% The packages are \textbf{NOT} provided so that people can stop
% upgrading their \LaTeX{} system. They will contain only fixes of a
% certain nature, others will still go into the kernel and extensions
% in form of packages, and support files will still be added to the
% base system at regular intervals.
%
%
% \subsection{Using \Lpack{fixltx2e}}
%
% To use the \Lpack{fixltx2e} package include the line
% \begin{quote}
%   |\usepackage{fixltx2e}[|\meta{date}|]|
% \end{quote}
% into the preamble of your document, where \meta{date} is the date of
% the \Lpack{fixltx2e} package that you are using. 
% This way your document will produce a warning if processed at a site
% that only has an older version of of this package.
%
% \subsection{Using \Lpack{fix-cm}}
%
% \begin{sloppypar}
% To use the \Lpack{fix-cm} package, 
% load \danger it \emph{before} \cmd{\documentclass},
% and use the command \cmd{\RequirePackage} to do so, rather than the
% normal \cmd{\usepackage}:
% \end{sloppypar}
% \begin{verse}
%   |\RequirePackage{fix-cm}|\\
%   |\documentclass| \dots
% \end{verse}
% \textbf{Do not to load any other package before the document class}, 
% unless you have a thorough understanding of the \LaTeX{} internals 
% and know exactly what you are doing!
%
%
% \section{Fixes added}
%
% This section describes all the fixes/features that have been added
% to the initial release of the package. If applicable the bug report
% info (see \texttt{bugs.txt}) is given.

% >Description:
% as documented in lamport's book, p. 198, concerning figure
% placement, "a figure will not be printed before an earlier
% figure, and a table will not be printed before an earlier
% table."  however, there is a footnote stating, "However,
% in two-column page style, a single-column figure can come before
% an earlier double-column figure, and vice versa."
% 
% this twocolumn behavior is undesireable---at least by me and
% most professional organizations i publish in.  ed snyzter developed
% a hack fix for 2.09 several years ago which links the two
% counters, but i have not run across a similar "fix" for 2e...
% \end{verbatim}
%
% Originally fixed in package \Lpack{fix2col} which was merged into
% this package. Documentation and code from this package have been
% merged into this file.
%
% \subsubsection{Notes on the Implementation Strategy}
%
% The standard output routine maintains two lists of floats that have
% been `deferred' for later consideration. One list for single column
% floats, and one for double column floats (which are always
% immediately put onto their deferred list). This mechanism means
% that \LaTeX\ `knows' which type of float is contained in each box
% by the list that it is processing, but having two lists means
% that there is no mechanism for preserving the order between the
% floats in each list.
%
% The solution to this problem consists of two small changes to
% the output routine.
%
% Firstly, abandon the `double column float list' |\@dbldeferlist|
% and change every command where it is used so that instead the
% same |\@deferlist| is used as for single column floats.
% That one change ensures that double and single column floats
% stay in the same sequence, but as \LaTeX\ no longer `knows'
% whether a float is double or single column, it will happily
% insert a double float into a single column, overprinting the
% other column, or the margin.
%
% The second change is to provide an alternative mechanism for
% recording the two column floats. \LaTeX\ already has a compact
% mechanism for recording float information, an integer count register
% assigned to each float records information about the `type' of float
% `figure', `table' and the position information `htp' etc.
%
% The type information is stored in the `high' bits, one bit position
% (above `32') allocated to each float type. The `low' bits store
% information about the allowed positions, one bit each allocated for
% |h t b p|.  In the \LaTeX2.09 system, the bit corresponding to `16'
% formed a `boundary' between these two sets of information, and it
% was never actually used by the system. Ed Sznyter's
% \package{fixfloats} package not unreasonably used this position to
% store the double column information, setting the bit for double
% column floats. Then at each point in the output routine at which a
% float is committed to a certain region, an additional check must be
% made to check that the float is (or is not) double column. If it
% spans the wrong number of columns it is deferred rather than being
% added. 
%
% Unfortunately the bit `16' is not available in \LaTeXe. It is used
% to encode the extra float position possibility `|!|' that was added
% in that system. It would be possible to use position `32' and to
% move the flags for `table', `figure',\ldots\ up one position, to
% start at 64, but this would mean that in principle one less float
% type would be supported, and more importantly is likely to break
% any other packages that assume anything about the output routine
% internals. So here I instead use another mechanism for flagging
% double column floats: By default all floats have depth 0pt.
% This package arranges that double column ones have depth 1sp.
% This information may then be used in the same manner as in
% the \package{fixfloats} package, to defer any floats that are not of
% the correct column spanning type.
%

% >Description:
% When setting the document in two columns
% the headline shows the top mark of the second column,
% but it should show the top mark of the first column.
% \end{verbatim}
%
% Originally fixed in package \Lpack{fix2col} which was merged into
% this package. Documentation and code from this package have been
% merged into this file.
%
% \subsubsection{Notes on the Implementation Strategy}
%
% The standard \LaTeX\ twocolumn system works internally by making
% each column a separate `page' that is passed independently to \TeX's
% pagebreaker. (Unlike say the \package{multicol} package, where all
% columns are gathered together and then split into columns later,
% using |\vsplit|.) This means that the primitive \TeX\ marks that are
% normally used for header information, are globally reset after the
% first column. By default \LaTeX\ does nothing about this.
% A good solution is provided by Piet van Oostrum (building on earlier
% work of Joe Pallas) in his \package{fixmarks} package.
%
% After the first column box has been collected the mark information
% for that box is saved, so that any |\firstmark| can be
% `artificially' used to set the page-level marks after the second
% column has been collected. (The second column |\firstmark| is not
% normally required.) Unfortunately \TeX\ does not provide a direct
% way of knowing if any marks are in the page, |\firstmark| always has a
% value from previous pages, even if there is no mark in this page.
% The solution is to make a copy of the box and then |\vsplit| it
% so that any marks show up as |\splitfirstmark|.
%
% The use of |\vsplit| does mean that the output routine will globally
% change the value of |\splitfirstmark| and
% |\splitbotmark|. The \package{fixmarks} package goes to some trouble
% to save and restore these values so that the output routine does
% \emph{not} change the values. This part of \package{fixmarks} is not
% copied here as it is quite costly (having to be run on every page) and
% there is no reason why anyone writing code using |\vsplit| should
% allow the output routine to be triggered before the split marks have
% been accessed.

% \subsection{Using EC fonts (T1 encoding) makes my documents look
%             bl**dy horrible (from c.t.t.)\\
%             I can't use arbitrary sizes with CM fonts (from c.t.t.)}
%
% No I'm not trying to collect any cites from the news group
% discussion on this topic. In a nutshell, if one adds
%\begin{verbatim}
%\usepackage[T1]{fontenc}
%\end{verbatim}
% to a document that uses the Computer Modern typefaces, 
% then not only the T1 encoding is used but the fonts
% used in the document look noticeably different. This is due to the fact
% that the EC fonts have more font series designs, e.g.\ a 14.4\,pt bold
% etc and those get used in the standard \texttt{.fd} files, while
% with Computer Modern (in OT1 encoding) such sizes were scaled
% versions of smaller sizes---with a noticeable different look and
% feel.
%
% So we provide a package \Lpack{fix-cm} to ensure that comparable
% definitions are used. In addition to that, the package
% \Lpack{fix-cm} also enables continuous scaling of the CM fonts.
% This package was written by Walter Schmidt.
%
%
%
%^^A \section{The macro package \textsf{fix-cm} for \LaTeXe}
%
%^^A The documentation in this section was prepared by Walter Schmidt.
%
%
%
% \subsubsection{What \Lpack{fix-cm} does} 
%
% ^^A Are you bothered by the T1 and TS1 encoded Computer Modern fonts,
% ^^A which look partially worse than the traditional ones?  Would you
% ^^A like to use the CM fonts with arbitrary sizes?  If so, the macro
% ^^A package \Lpack{fix-cm} can help you.
%
% Loading the package \Lpack{fix-cm} changes the font definitions of the 
% Computer Modern fonts, in order to achieve the following effects:
% \begin{itemize}
%   \item
%   The appearance of the T1 and TS1 encoded CM fonts (aka `EC') is
%   made as similar as possible to the traditional (OT1 encoded) ones.
%   Particularly, a number of broken or ugly design sizes are no
%   longer used, the look of the bold sans serif typeface at large
%   sizes is considerably improved, and mismatches between the text
%   fonts and the corresponding math fonts are avoided.  As a side
%   effect, PostScript and PDF documents may become smaller, because
%   fewer fonts need to be embedded.
%   \item
%   The Computer Modern fonts are made available with arbitrary sizes.
%   \item
%   Only those design sizes of the fonts will be used, that are
%   normally available in Type1 format, too.  You need not load the
%   extra package \Lpack{cmmib57} for this purpose.
% \end{itemize}
% The package acts on the following font families:
% \begin{itemize}
%   \item
%   The text font families \file{cmr}, \file{cmss}, \file{cmtt} and 
%   \file{cmvtt} with OT1, T1 and TS1 encoding.
%   \item 
%   The default math fonts used by \LaTeX, i.e., the font families 
%   \file{cmm} with encoding OML and \file{cms} with encoding OMS.
%   \item
%   The symbols used by the package \Lpack{latexsym}, i.e., the font
%   family \file{lasy}.
% \end{itemize}
% Note that the package does \emph{not} act on:
% \begin{itemize}
% \item Font families such as CM~Fibonacci, CM~Dunhill etc.,
%   which are provided for experimental purposes or for fun only.
% \item
%   CM text fonts with character sets other than Latin, e.g.,
%   Cyrillic.  Loading of the required font and encoding definitions
%   while the fonts are not actually used, would not be a good idea.
%   This should be addressed by particular packages or by changing the
%   standard FDs of these fonts.
% \item
%   Extra math fonts such as the AMS symbol fonts.  While
%   they match the style of Computer Modern, they are frequently used
%   in conjunction with other font families, too.  Thus,
%   \Lpack{fix-cm} is obviously not the right place to make sure that
%   they can be scaled continuously.  Ask the maintainers of these
%   fonts to provide this feature, which is badly needed!
% \item
%   The math extension font \file{cmex}.  Whether or not this font
%   should be scaled is a question of its own, and there are other
%   packages (\Lpack{exscale}, \Lpack{amsmath}, \Lpack{amsfonts}) to
%   take care of it.
% \end{itemize}
%
% \subsubsection{How to load the package}
% \begin{sloppypar}
% The package should be loaded \danger \emph{before} \cmd{\documentclass},
% using the command |\RequirePackage{fix-cm}|, rather than the
% normal \cmd{\usepackage}.
% Rationale:  
% If the package is loaded in the preamble, a preceding package or
% even the code of the document class may have used any of the CM
% fonts already.  However, the definitions of those fonts, that are
% already in use, cannot be changed any more.
% \end{sloppypar}
%
% \subsubsection{Usage notes}
% In contrast to what you may expect, \Lpack{fix-cm} does \emph{not}
% ensure that line and page breaks stay the same, when you switch an
% existing document from OT1 to T1 encoding.  The package does not
% turn off all of the additional design sizes in the EC fonts
% collection: Those, that contribute considerably to the typographical
% quality and do not conflict with the math fonts,
% are---indeed---used.
%
% Be careful when using arbitrary, non-standard font sizes with
% applications that need bitmap fonts: You may end up \danger with
% lots of possibly huge \file{.pk} files.  Also, \MF{} chokes
% sometimes on extremely small or large sizes, because of arithmetic
% problems.
%   
% \Lpack{fix-cm} supersedes the experimental packages \Lpack{cmsd} and
% \Lpack{fix-ec}, which are no longer distributed.
%
% The packages \Lpack{type1cm} and \Lpack{type1ec} must not be loaded
% additionally; they enable only continuous scaling.  
%

% ones where really quite different from one another.

% \subsection{Using EC fonts (T1 encoding) makes my documents look
%             bl**dy horrible}
%
% \subsubsection{Preliminaries} 
% The \LaTeX{} kernel does not declare the font encoding TS1.
% However, we are going to set up font definitions for this encoding,
% so we have to declare it now.
%    \begin{macrocode}
%<*fix-cm>
\input{ts1enc.def}
%    \end{macrocode}
%
% In case the package is loaded in the preamble, any of the CM fonts may
% have been used already and cannot be redefined.  Yet we try to
% intercept at least the problem that is most likely to occur, i.e., 
% a hidden \cmd{\normalfont}.  Most of the standard definitions 
% are ok, but those for T1 encoding and 10.95\,pt need to be removed:
%    \begin{macrocode}
\expandafter \let \csname T1/cmr/m/n/10.95\endcsname \relax
\expandafter \let \csname T1/cmss/m/n/10.95\endcsname \relax
\expandafter \let \csname T1/cmtt/m/n/10.95\endcsname \relax
\expandafter \let \csname T1/cmvtt/m/n/10.95\endcsname \relax
%    \end{macrocode}
%
% \Lpack{fix-cm} may still fail, if the EC fonts are preloaded in the 
% \LaTeX{} format file. This situation is, however, very unlikely and could occur
