+% \subsection{Page-wise Float Placement}
+% \label{sec:imp-ovv-float}
+% \changes{v1.32-3}{2015/10/10}
+% 	{Add the section ``Page-wise Float Placement'' to discuss the
+%	 page-wise float problem.} 
+% 
+% In the release on 2015/01/10, \LaTeX{}'s float placement mechanism was
+% drastically changed to avoid {\em out-of-order\/} appearance of \pwise{}
+% floats as follows.  Since the cause of overtaking of a \pwise{} float by a
+% \cwise{} float is that they are in two separated lists \!\@dbldeferlist!
+% for the former and \!\@deferlist! for the latter, in the new implemenation
+% the two lists are merged to let all floats go to \!\@deferlist!.  To
+% distinguish \pwise{} and \cwise{} floats in the list, \!\end@dblfloat!
+% lets the \pwise{} float processed by the macro have a special depth of
+% |1sp|, while depth of \cwise{} floats are 0 since \!\@endfloatbox! add a
+% \!\vskip! of 0 at the end of the box of floats.
+% 
+% Then all macros invoked in \!\output!-routine examine the depth of floats
+% in the list they are working on against a newly introduced macro
+% \!\f@depth! by also newly introduced \!\@testwrongwidth!, so that they
+% process only floats of a page/column category specified by \!\f@depth!,
+% while those not matching to \!\f@depth! are let go to \!\@deferlist! to
+% inhibit succeeding floats of the same type to overtake them.  The
+% \!\def!inition of \!\f@depth! is done only by modified
+% \!\@dblfloatplacement!, always invoked in a group, to let it have |1sp| so
+% that float placement macros usually work on \cwise{} ones with the default
+% setting of $\!\f@depth!=\!\z@!$ except for special occasions in which the
+% placement of \pwise{} floats is tried.
+% 
+% Though the mechanism should work well with {\em ordinary\/} multi-columned
+% documents, it is incompatible with \Paracol{} almost inherently.  That is,
+% in the first place we have to separate float-related lists into the sets
+% of them corresponding to columns as we do\footnote{

+% 

+% If counters \counter{figure} and \counter{table} are global and we have to
+% avoid inter-column overtaking with respect to, for example, the partial
+% ordering rooted by the top-left corner, merging \cwise{} lists together
+% with the merge of \cs{@deferlist} and \cs{@dbldeferlist} might be a
+% solution to let the depth of a \cwise{} float be $c\,\texttt{sp}$ while
+% that of \pwise{} is $\C$\,\texttt{sp}.  However such implementation is not
+% only tough but also doubtful to be worthwhile.}.
+% 

+% Therefore, it is obviously nonsense to merge the list for  \pwise{} floats,
+% i.e., \!\@dbldeferlist!, to \!\@deferlist! of a particular column, and
+% thus we have to stick with the conventional implementation to process
+% \pwise{} and \cwise{} floats separately as follows.
+% 

+% \begin{enumerate}\def\labelenumi{(\arabic{enumi})}
+% \item
+% \label{item:ovv-float-end@dblfloat}
+% We \!\def!ine our own \!\end@dblfloat! namely \!\pcol@end@dblfloat!
+% whose definition is exactly same as the old version of \!\end@dblfloat!,
+% and replace the new version with it by \!\let!ting them equivalent in
+% \!\pcol@zparacol! by which start \env{paracol} environments.  Therefore,
+% \pwise{} floats composed in a \env{paracol} environment is processed in
+% the traditional way, i.e., being inclueded in \!\@dbldeferlist! rather than
+% \!\@deferlist! and having ordinary depth 0.
+% 
+% \item
+% \label{item:ovv-float-@dblfloatplacement}
+% Each invocation of \!\@dblfloatplacement! in our own \!\output!-routine is
+% followed by a \!\let! to nullify the setting of $\!\f@depth!=|1sp|$ done
+% by \!\@dblfloatplacement! by doing \!\f@depth!=\!\z@!.  By this setting,
+% \!\@tryfcolumn! in \!\pcol@startpage!  and \!\@makefcolumn! in
+% \!\pcol@output@clear! work on their argument \!\@dbldeferlist! in the way
+% exactly same as in 2014 or before.
+% 
+% \item
+% \label{item:ovv-float-@addtodblcol}
+% Among \LaTeX's macros in its \!\output!-routine which we use in our own
+% one as well, only \!\@addtodblcol! changed its target from
+% \!\@dbldeferlist! to \!\@deferlist!.  That is, if the macro fails to put a
+% \pwise{} float to the page we just have started by \!\pcol@startpage!,
+% the float is added to \!\@deferlist! rather than \!\@dbldeferlist!.
+% Therefore, when we apply \!\@sdblcolelt! to the copy of \!\@dbldeferlist!
+% to invoke \!\@addtodblcol! for each of its element float, we have to save
+% \!\@deferlist! somewhere, to \!\reserved@c! in reality, and clear it prior
+% to the application.  Then after all elements are processed, we have to let
+% \!\@dbldeferlist! have what \!\@deferlist! have, while \!\@deferlist!
+% should regain its origial contents from the saved place.  A subtle issue
+% is that we might work with \LaTeX{} of 2014 or older in which the floats
+% are returned to \!\@dbldeferlist!.  Therefore to make \Paracol{}
+% compatible with both of new and old versions, we have to {\em add}
+% \!\@deferlist! to \!\@dbldeferlist! rather than replacing
+% \!\@dbldeferlist! with \!\@deferlist!.  This addition should work well,
+% because we clear both lists before the application of \!\@sdblcolelt!  and
+% then one of them will have the still-deferred floats after the application
+% while the other remains empty.
+% 
+% \item
+% \label{item:ovv-float-@output@start}
+% We convert \!\@deferlist! to \!\@dbldeferlist! in \!\pcol@output@start! to
+% start a \env{paracol} environment, and peforms the reverse operation in
+% \!\pcol@output@end! to close the environment.  Though it is very unlikely
+% (or maybe impossible) that the \!\@deferlist! {\em imported\/} in the
+% former operation has \LaTeX's (i.e., not \Paracol's) double-column floats
+% of |1sp| deep, we make such floats old-fashioned making their depth 0 so
+% that they can be put in a page built in the \env{paracol} environment.  On
+% the other hand, the latter cannot {\em export\/} a list having floats of
+% |1sp| deep because they have been produced in the closing \env{paracol}
+% environment or have passed our {\em custom\/} \!\pcol@output@start! when
+% they were imported\footnote{

+% 

+% Therefore, if one try to {\em smuggle\/} a double-column float of the new
+% scheme into a \env{paracol} and to pass it through the environment to
+% another double-column world, the float will become a single-column one.
+% Even if such guy really exists and complains abount this transformation,
+% however, we have good right to say ``don't do that''.}.
+% \end{enumerate}
+% 

+% Note that the operations (1), (2) and (4) are fully compatible with 2014
+% or older version of \LaTeX{}, because with the old version; (1) 
+% \!\pcol@end@dblfloat! is equivalent to \!\end@dblfloat!; (2) modification
+% of \!\f@depth! cannot be seen because it does not exist;  and (4) we
+% virtually do nothing in the importation.  As for (3), we explicitly take
+% care of the compatibility as shown above.

+% Another debugging tool is for investigating memory leak problems.  Since
+% \Paracol{} uses \!\insert! registers for various purposes, management
+% operations of them especially that for proper release of them are crusial
+% for the correctness of the implmentation.  A source of toughness in
+% debugging {\em memory leak} caused by missing a release of a register back
+% to \!\@freelist! is that the resulting shortage is revealed long after the
+% leakage to make it hard to find the point of the leakage.
+% 
+% The set of macros is to help such debugging by logging the aquire and
+% release of \!\insert! registers into a file named $\arg{job}|.fls|$
+% associated with \!\pcol@F@write! where $\arg{job}$ is given by
+% \!\jobname!.  After opened when \Paracol{} is loaded, the file is written by
+% $\!\pcol@FF!\arg{msg_a}\arg{msg_b}$ with a line of the following form,
+% where $p=\!\pcol@page!$, $c=\!\pcol@currcol!$, $\ptop=\!\pcol@toppage!$,
+% $\page(p)=\!\c@page!$, and $\arg{n}_b=\!\pcol@F@n!$ is the cardinality of
+% \!\@deferlist! counted by \!\pcol@F@count!.
+% 

+% \begin{itemize}\item[]
+% $\arg{msg_a}|(|p|:|c|/|\ptop|:|\page(p)|)|=\arg{n_b}\arg{msg_b}$
+% \end{itemize}
+% 

+% The argument $\arg{msg_b}$ is empty when $\!\pcol@FF!$ is invoked from
+% $\!\pcol@F!\arg{msg_a}$ for snapshot, while
+% $\arg{msg_b}=\hbox{`|<=|$\arg{n_b}$'}$ when invoked from

-%
-%  The different types of floats are identified by a \meta{type} name,
-%  which is the name of the counter for that kind of float.  For
-%  example, figures are of type `figure' and tables are of type `table'.
-%  Each \meta{type} has associated a positive \meta{type number}, which
-%  is a power of two.  E.g.,\\
-%  figures might be have type number~1, tables type number~2, programs
-%  type number~4, etc.
-%
-%  The locations where a float can go are specified by a
-%  \meta{placement specifier}, which is a list of the possible
-%  locations, each denoted by a letter as follows:
-%    \begin{center}
-%    \begin{tabular}{l@{ : }l@{ --- }l}
-%     h & here   & at the current location in the text.\\
-%     t & top    & at the top of a text page.\\
-%     b & bottom & at the bottom of a text page.\\
-%     p & page   & on a separate float page
-%    \end{tabular}
-%    \end{center}
-%  In addition, in conjunction with these, you can use `!' which means
-%  that the current values of the float positioning parameters are
-%  ignored for this float. (Has no effect on `p', float page
-%  positioning.)
-%  For example, `pht' specifies that the float can appear in any of
-%  three locations: page, here or top.

-% Where floats may appear on a page, and how many may appear there
-% are specified by the following float placement parameters.  The
-% numbers are named like counters so the user can set them with
-% the ordinary counter-setting commands.
-%
-%  \c@topnumber      : Number of floats allowed at the top of a column.
-%  \topfraction      : Fraction of column that can be devoted to floats.
-%  \c@dbltopnumber, \dbltopfraction 
-%                    : Same as above, but for double-column floats.
-%  \c@bottomnumber, \bottomfraction 
-%                    : Same as above for bottom of page.
-%  \c@totalnumber    : Number of floats allowed in a single column,
-%                          including in-text floats.
-%  \textfraction     :Minimum fraction of column that must contain text.
-%  \floatpagefraction: Minimum fraction of page that must be taken
-%                          up by float page.
-%  \dblfloatpagefraction 
-%                    : Same as above, for double-column floats.
-%
-% The document style must define the following.
-%
-%    \fps@TYPE   : The default placement specifier for floats of type
-%                  TYPE. 
-%
-%    \ftype@TYPE : The type number for floats of type TYPE.
-%
-%    \ext@TYPE   : The file extension indicating the file on which the
-%                  contents list for float type TYPE is stored.
-%                    For example,  \ext@figure = 'lof'.
-%
-%    \fnum@TYPE  : A macro to generate the figure number for a caption.
-%                  For example, \fnum@TYPE == Figure \thefigure.
-%
-%    \@makecaption{NUM}{TEXT} : 
-%              A macro to make a caption, with NUM the value
-%              produced by \fnum@... and TEXT the text of the caption.
-%              It can assume it's in a \parbox of the appropriate width.
-%
-% \@float{TYPE}[PLACEMENT] : This macro begins a float environment for a
-%     single-column float of type TYPE with PLACEMENT as the placement
-%     specifier.  The default value of PLACEMENT is defined by

-% The paragraph setting parameters are normalised at this point, however

-% context so |\@setminipage| is called if needed.
-%
-% The float mechanism, like minipage, sets the flag |@minipage| true
-% before executing the user-supplied text. Many \LaTeX\ constructs
-% test for this flag and do not add vertical space when it is true.
-% The intention is that this emulates \TeX's `top of page' behaviour.
-% The flag must be set false at the start of the first paragraph. This
-% is achieved by a redefinition of |\everypar|, but the call to
-% |\@parboxrestore| removes that redefinition, so it is re-inserted 
-% if needed. If the flag is already false then the |\caption| was not
-% the first entry in the float, and so some other paragraph has already
-% activated the special |\everypar|. In this case no further action is
-% needed.

-%   MARGINAL NOTES:
-%
-%   Marginal notes use the same mechanism as floats to communicate
-%   with the \output routine.  Marginal notes are distinguished from
-%   floats by having a negative placement specification.  The command
-%   \marginpar [LTEXT]{RTEXT} generates a marginal note in a parbox,
-%   using LTEXT if it's on the left and RTEXT if it's on the right.
-%   (Default is RTEXT = LTEXT.)  It uses the following parameters.
-%
-%   \marginparwidth : Width of marginal notes.
-%   \marginparsep   : Distance between marginal note and text.
-%        the page layout to determine how to move the marginal
-%        note into the margin.   E.g., \@leftmarginskip ==
-%        \hskip -\marginparwidth \hskip -\marginparsep .
-%   \marginparpush  :  Minimum vertical separation between \marginpar's
-%
-%  Marginal notes are normally put on the outside of the page
-%  if @mparswitch = true, and on the right if @mparswitch = false.
-%  The command \reversemarginpar reverses the side where they
-%  are put.  \normalmarginpar undoes \reversemarginpar.
-%  These commands have no effect for two-column output.
-%
-%  SURPRISE: if two marginal notes appear on the same line of
-%  text, then the second one could appear on the next page, in
-%  a funny position.

-%
-%   \footnote{NOTE}       : User command to insert a footnote.
-%
-%   \footnote[NUM]{NOTE}: User command to insert a footnote numbered
-%                       NUM, where NUM is a number -- 1, 2,
-%                       etc.  For example, if footnotes are numbered
-%                       *, **, etc. within pages, then \footnote[2]{...}
-%                       produces footnote '**'.  This command does not
-%                       step the footnote counter.
-%
-%   \footnotemark[NUM] : Command to produce just the footnote mark in
-%                        the text, but no footnote.  With no argument,
-%                        it steps the footnote counter before generating
-%                        the mark.
-%
-%   \footnotetext[NUM]{TEXT} : Command to produce the footnote but
-%                              no mark.  \footnote is equivalent to
-%                              \footnotemark \footnotetext .
-%
-%   As in PLAIN, footnotes use \insert\footins, and the following
-%   parameters: 
-%
-%   \footnotesize   : Size-changing command for footnotes.
-%
-%   \footnotesep    : The height of a strut placed at the beginning of
-%                     every footnote.
-%   \skip\footins   : Space between main text and footnotes.  The rule
-%                     separating footnotes from text occurs in this
-%                     space. This space lies above the strut of height
-%                     \footnotesep which is at the beginning of the
-%                     first footnote.
-%   \footnoterule   : Macro to draw the rule separating footnotes from
-%                     text. It is executed right after a \vspace of
-%                     \skip\footins. It should take zero vertical
-%                     space--i.e., it should to a negative skip to
-%                     compensate for any positive space it occupies.
-%                     (See PLAIN.TEX.)
-%
-%   \interfootnotelinepenalty : Interline penalty for footnotes.
-%
-%   \thefootnote : In usual LaTeX style, produces the footnote number.
-%                  If footnotes are to be numbered within pages, then
-%                  the document style file must include an \@addtoreset
-%                  command to cause the footnote counter to be reset
-%                  when the page counter is stepped.  This is not a good
-%                  idea, though, because the counter will not always be
-%                  reset in time to ensure that the first footnote on a
-%                  page is footnote number one.
-%
-%   \@thefnmark : Holds the current footnote's mark--e.g., \dag or '1'
-%                 or 'a'. 
-%
-%   \@mpfnnumber  : A macro that generates the numbers for \footnote
-%                  and \footnotemark commands. It == \thefootnote
-%                  outside a minipage environment, but can be
-%                  changed inside to generate numbers for
-%                  \footnote's.
-%
-%   \@makefnmark : A macro to generate the footnote marker from
-%                 \@thefnmark The default definition was
-%                 \hbox{$^\@thefnmark$}.
-%
-%                 This is now replaced by
-%                 \textsuperscript{\@thefnmark}
-%
-%   \@makefntext{NOTE} :
-%        Must produce the actual footnote, using \@thefnmark as the mark
-%        of the footnote and NOTE as the text.  It is called when
-%        effectively  inside a \parbox, with \hsize = \columnwidth.
-%          For example, it might be as simple as
-%               $^{\@thefnmark}$  NOTE
-%
-% In a minipage environment, \footnote and \footnotetext are redefined
-% so that
-%    (a) they use the counter mpfootnote
-%    (b) the footnotes they produce go at the bottom of the minipage.
-% The switch is accomplished by letting \@mpfn == footnote or mpfootnote
-% and \thempfn == \thefootnote or \thempfootnote, and by redefining
-% \@footnotetext to be \@mpfootnotetext in the minipage.

+%	{Add comments about the out-of-order appearance of page-wise floats
+%	 even with \protect\LaTeX-2015/01/10 or later.}
+% In the release on 2015/01/10, \LaTeX{} changed its mechanism of the
+% placement of double-column floats (or in our terminology, \pwise{}
+% floats) to avoid {\em out-of-order\/} appearance of them.  That is, until
+% the release on 2014/05/01 a double-column float (e.g., \env{figure*}) can
+% be overtaken by a single-column float of the same category (e.g.,
+% \env{figure}) when they cannot be put into the page in which texts around
+% them are put.  In order to cope with the problem, the new version merged
+% two lists to keep {\em deferred\/} double- and single-column floats into
+% one so that the appearance order of them is determined by their order in
+% the single list.  Though this change should have made people happy when
+% they typeset {\em ordinary\/} two-column (or multiple-column) documents,
+% the new feature might not be welcomed by \Paracol{} users because your
+% parallel-columns have their own {\em stream\/} of floats to be put in the
+% corresponding columns.  Therefore, and for the sake of simplicity of
+% \Paracol's implementation, the author decided to nullify this new feature
+% in \env{paracol} environments.  That is, even with new releases of
+% \LaTeX{}, your \pwise{} floats given in a \env{paracol} environment can be
+% overtaken by \cwise{} floats.
