+fix2col.dtx
+fix2col.ins
+   Superceeded by fixltx2e, part of the base LaTeX distribution.
+   Two column fixes.
+   a) Fix mark handling so \firstmark is taken from the first column
+      if that column has marks at all.
+      (A copy of Piet van Oostrum's fixmarks package, more or less.)
+   b) Keep two column floats like figure* in sequence with single
+      column floats like figure.
+      (Modelled on  Ed Sznyter's 2.09 package, fixfloats.)

+% \section{Introduction}
+% This package makes two independent changes to \LaTeX's two column
+% output routine to fix the following two longstanding `features'.
+%
+% \begin{itemize}
+% \item
+% If the \TeX\ mark system is used (for example using the 
+% `headings' page style in the standard \LaTeX\ classes) then any marks
+% that originate on the first column are `lost' as \LaTeX\ constructs
+% the second column. An example document showing how this can result
+% in incorrect page headings may be found in the latex bug database:\\
+% \url{http://www.uni-mainz.de/cgi-bin/ltxbugs2html?pr=latex/2613}
+%
+% \item
+% The second feature is documented in the \LaTeX\ book. By default
+% \LaTeX\ does not attempt to keep double and single column floats in
+% sequence, so if `Figure 1' is a double column float produced with
+% |figure*|, then it may float 
+% after `Figure 2' if that is a single column, |figure|, float.
+% Further correspondence about this may also be found in the
+% bug database:\\
+% \url{http://www.uni-mainz.de/cgi-bin/ltxbugs2html?pr=latex/2346}

+% \section{Notes on the Implementation Strategies}
+%
+% \subsection{Preserving Marks}
+%
+% 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{Preserving Float Order}
+%
+% 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.
+%
+% Use of the package showed that one also has to change the way
+% \LaTeX{} handles star-form floats: if they are immediately deferred
+% (as done normally) certain situations can still result in the float
+% sequence getting out of order. This happens when a floats are placed
+% in the middle of a paragraph.  In that case the wide float is
+% deferred immediately while a column wide float early on in the same
+% paragraph might not be handled until the end of the paragraph when
+% it is finally seen by the output routine. Since by that time the
+% wide float is already on the |\@deferlist| the column float will
+% also end up there (which is not only incorrect because it may have
+% fitted onto the page but also because it is then placed at the end
+% of this list). Version v0.03 now fixes this problem.

+%
+% \subsection{Preserving Marks}
+%
+% This is just a change to the single command |\@outputdblcol|
+% so that it saves mark information for the first column and restores
+% it in the second column.
+%    \begin{macrocode}
+\def\@outputdblcol{%
+  \if@firstcolumn
+    \global\@firstcolumnfalse
+%    \end{macrocode}
+% Save the left column

+    \splitmaxdepth\maxdimen
+    \vbadness\maxdimen
+    \setbox\@outputbox\vsplit\@outputbox to\maxdimen
+%    \end{macrocode}
+%
+% One minor difference from the current \package{fixmarks}, pass the 
+% marks through a token register to stop any |#| tokens causing an
+% error in a |\def|.
+%    \begin{macrocode}
+    \toks@\expandafter{\topmark}%
+    \xdef\@firstcoltopmark{\the\toks@}%
+    \toks@\expandafter{\splitfirstmark}%
+    \xdef\@firstcolfirstmark{\the\toks@}%
+%    \end{macrocode}
+%
+% This test does not work if truly empty marks have been inserted, but
+% \LaTeX\ marks should always have (at least) two brace groups.
+% (Except before the first mark is used, when the marks are empty,
+% but that is OK here.)
+%    \begin{macrocode}
