%\section{Introduction}
% When writing yet another \LaTeX\ introduction with a demonstration of
% font sizes, I discovered that \cmd{\Huge} and \cmd{\huge} were set to
% the same size. No good for a demonstration! I localized the definition
% in the \fln{size12.clo} class option file and found that the font size
% for \cmd{\Huge} had to be increased from 24.88pt to 29.86pt.
%
% \DescribeMacro{\HUGE}
% Therefore, I produced a package \this\ redefining \cmd{\Huge} and
% defining an even ``bigger'' font size command \cmd{\HUGE}, because I
% wanted to be able to use font sizes up to 35.83pt, as provided by the
% \fntec\ fonts' standard edition.
%
% \DescribeMacro{\ssmall}
% Additionally, I defined a size command \cmd{\ssmall} filling the
% gap between the sizes selectable by \cmd{\tiny} and \cmd{\scriptsize}.
%
% The documentation in the \LaTeXe\ distribution's source file
% \fln{fontdef.dtx} reminded me to also declare math sizes for the new
% text sizes.
% When studying the docs, I found that the math script sizes defined in
% \fln{fontdef.dtx} grew faster than the text sizes, and that at least
% the script sizes for 24.88pt seemed to be absolutely inappropriate.
% Therefore, I designed two sets of text/math size combinations
% including the new 29.86pt and 35.83pt text sizes,
% one set just fixing the 25pt math script and scriptscript sizes,
% and another one with somewhat smaller scriptscript sizes in order to
% maintain the typical $10:7:5$ ratio for text sizes from 10pt upwards.
% The math size changings can be activated by means of options
% passed to the \this\ package.
%
% For testing the new sizes and for visualizing the effects of the math size
% settings, a \LaTeX\ file \testfile\ containing sample text and math
% expressions at various sizes is provided.
%
%\section{User Interface}
% The \this\ package can be loaded by the \LaTeXe\ command
% \begin{quote}
% |\usepackage|\oarg{options}|{|\thisfln{}|}|
% \end{quote}
% By default, \this\ neither redefines existing macros nor changes
% the standard math size declarations.
% However, the package provides the additional font size selection commands
% \cmd{\HUGE} and \cmd{\ssmall}, and declares math sizes
% for the new 29.86pt and 35.83pt text sizes.
%
% Available Options are:
% \begin{description}
% \item[\opt{10pt}]
% This option provides the same settings as the default.
% \cmd{\HUGE} is defined to select a 29.86pt font size, and
% \cmd{\ssmall} is made to give 6pt.
% These definitions continuously extend the set of size commands given in
% the \fln{size10.clo} standard class option file.
%
% \item[\opt{11pt}]
% This option makes \cmd{\HUGE} and \cmd{\ssmall} select 29.86pt and
% 7pt, respectively, which is suitable for use with the settings given in
% the \fln{size11.clo} standard class option file.
%
% \item[\opt{12pt}]
% With this option, \cmd{\HUGE} and \cmd{\ssmall} are defined to
% select 35.83pt and 7pt, respectively.
%
% Additionally, the size selection command \cmd{\Huge} is redefined
% to give 29.86pt.
% This is done because the setting given in the \fln{size12.clo} standard
% class option file saturates the \cmd{\Huge} font size at the same level
% as given by \cmd{\huge} (24.88pt)---presumably with the \fntcm\ font
% restrictions of old \LaTeX~2.09 in mind.
% Nowadays, with \LaTeXe's flexible \NFSS, font size selection commands
% are not associated with a predetermined font family any longer,
% hence such restrictions are out of place.
% Note that \NFSS\ automatically resorts to lower sizes if a demanded font
% size is not available, so standard \fntcm\ font users will not be
% affected by the new size settings, but \fntec\ font users can benefit
% from them.
%
% \item[\opt{ecpatch}]
% This is a bug fix for the \fntec\ font declarations given in the
% \LaTeXe\ releases from December 1996 through December 1997.
% Therein, the declarations of the \fntec\ fonts do not include
% font sizes above 24.88pt, although the \fntec\ font standard edition
% provides font metrics files for 29.86pt and 35.83pt.
% As a consequence, \NFSS\ would deny usage of those font sizes
% and substitute 24.88pt instead.
%
% The \opt{ecpatch} option installs macros which override any declaration
% of an \fntec\ font with an own declaration including the 29.86pt
% and 35.83pt sizes.
%
% Regard this patch as a temporary bug fix; the proper way requires
% updating the \LaTeXe\ distribution source file \fln{cmfonts.fdd}
% from which the \fln{t1cm*.fd} files are generated, and remaking the
% \LaTeXe\ format file.
% Indeed, a proper fix has been incorporated into the \LaTeXe\
% distribution shortly after December 1997; therefore, recent distributions
% should not require the \opt{ecpatch} option.
%
% As can be concluded from the above, the decision whether to use
% \opt{ecpatch} or not should be determined by the availibility of
% \fntec\ (\emph{not} \fntdc!) fonts and by the version of the
% \LaTeXe\ base distribution both of which may vary independently from the
% author's main \LaTeX\ input file.
% Therefore, the appropriate spot for invoking \opt{ecpatch}
% is a configuration file placed somewhere in the \LaTeXe\ input
% directory tree with filename \thisfln{.cfg},
% containing a line like
% \begin{quote}
%\begin{verbatim}
%\ExecuteOptions{ecpatch}
%\end{verbatim}
% \end{quote}
% This frees authors of \LaTeXe\ input files from the need of specifying
% \opt{ecpatch} themselves when using the \this\ package
% and thus preserves the portability of \LaTeXe\ documents across
% different \LaTeXe\ releases.
%
% Note that \opt{ecpatch} is useful only if the following conditions
% are met:
% \begin{enumerate}
% \item
% The ``official'' \fntec\ fonts are available,
% including TFM files for the sizes 29.86pt and 35.83pt.
% With \fntdc\ fonts instead, \opt{ecpatch} will not work
% correctly.\footnote{
% \opt{ecpatch} may work with the last (``new'')
% \fntdc\ font release if provided with TFM files for all standard
% \fntec\ font sizes.
% Typically, the 29.86pt size would be missing.}
% \item
% The \LaTeXe\ base has been configured to support \fntec\ fonts
% (i.e.\ \fln{cmfonts.fdd} has been unpacked by \fln{ec.ins}\footnote{
% Using \fln{newdc.ins} for \fntdc\ fonts with all TFM files mentioned
% above could also work.}).
% \item
% The \LaTeXe\ base (or at least its \fln{cmfonts.fdd}) has a release
% date before 1998. Later releases do not need \opt{ecpatch}.\footnote{
% Applying \opt{ecpatch} to newer \LaTeXe\ releases has not caused
% any harm in my testings so far.}
% \end{enumerate}
% Anyway---upgrading your system to a recent \LaTeXe\ base
% with ``official'' \fntec\ fonts would be a better solution
% than using \opt{ecpatch}.
%
% \item[\opt{normalscripts}]
% This option decreases the script and scriptscript sizes associated
% with the 24.88pt text size by one magstep, in order to damp the
% script size explosion defined in the \LaTeXe\ source file
% \fln{fontdef.dtx}.
% With this setting, a formula like $\frac{X}{Y}$ within a \cmd{\Huge}
% paragraph (e.\,g.\ a document title) does no longer affect line spacing,
% as should be.
%
% \item[\opt{smallscripts}]
% Starting from the \opt{normalscripts} math size settings, this option
% further reduces the scriptscript sizes associated with text sizes of
% 17.28pt and above.
% The idea behind this is to maintain an approximate $10:7:5$ ratio
% between text, script, and scriptscript sizes in bigger-than-normal
% writings.
% \end{description}
%
% The math script size option names roughly describe the changes to the
% standard \LaTeX\ setup.
% Therefore, \opt{normalscripts} may not look ``normal'' in the sense of
% ``just right'', but differs from the standard setup in 24.88pt
% writings only.
% I prefer \opt{smallscripts} which results in scriptscript sizes that are
% not really small---they are simply not as big as the standard ones.
% Note that this option only affects math expressions with nested fractions
% and/or sub-/superscripts in large writings (17.28pt text size and above),
% e.\,g.\ in titles or section headers.
% Therefore, it is quite likely that you have not encountered an example
% of that kind so far.
% But once you have, you should remember this package\dots
%
%\section{The test file \testfile}
% A test file \testfile\ is provided for evaluating the math size
% settings. You may rename it and then manipulate it as you wish,
% typically for testing the options passed to the \this\ package.
% The test document shows sample text and math expressions at various
% sizes, each framed above and below by horizontal lines delimiting the
% amount of vertical space that is normally available for math expressions
% within paragraphs of text.
% If the expressions overprint the delimiters, they are likely to cause
% stretching of the baseline skip when used within a paragraph.
%
% However, the output for sizes above 24.88pt may be erroneous or
% misleading under certain circumstances:
% \begin{itemize}
% \item
% Even when using \fntec\ text fonts, math expressions may still use
% \fntcm\ fonts which are limited to 24.88pt in their declarations
% to \NFSS\@.
% This does not matter for scripts and scriptscripts because even
% \cmd{\HUGE} writings do not request script sizes greater than 24.88pt.
% However, the main (i.\,e.\ non-script) symbols of math expressions in
% \cmd{\HUGE}, or even in \cmd{\Huge} (for \opt{12pt} documents),
% will be shrinked to 24.88pt size,
% thereby issuing \NFSS\ warnings about unavailable font sizes
% for OT1, OML, or OMS encodings.
% (If there are messages about unavailable T1 font sizes,
% you should try the \opt{ecpatch} option or get a recent
% version of \LaTeX\ and of the \fntec\ fonts.)
%
% \item
% As another effect of the main symbol size shrinking,
% the vertical position of the main math axis is lowered,
% thereby moving fraction rules towards the denominators.
%
% \item
% The calculation of the amount of vertical space available within a
% normal line yields wrong results if fonts with the desired size
% are not available.
% In detail, the appearant amount of free vertical space gets increased by
% twice the difference between the requested font size and the size chosen
% by \NFSS\@.
%
% If you use properly-declared \fntec\ fonts for testing the samples,
% this problem should not occur.
% \end{itemize}
%
% By adding extreme magnification factors to the \fntcm\ font declarations,
% I have verified that the aforementioned artifacts disappear
% when math fonts in the requested sizes are made available (though heavily
% ``bolded'' by the magnification).
% However, I have not included that hack for demonstration,
% in order not to provide any means for over-using the \fntcm\ math fonts.
% According to the \LaTeXe\ newsletters \fln{ltnews09.tex}
% and \fln{ltnews11.tex}, \TeX\ users can look forward to a modern
% math font concept allowing easy setup and use of alternate math fonts.
% Therefore, making documents which explicitly misuse \fntcm\ fonts for
% huge math expressions would be counterproductive.
% However, even without math fonts at more than 24.88pt, the improvements
% in typesetting huge math expressions can be demonstrated by varying
% the options passed to the \this\ package in the test file \testfile.

% The definitions given here are similar to most size command definitions
% in \LaTeXe's \fln{classes.dtx}.
% The following rules have been observed and taken as guidelines:
% \begin{itemize}
% \item
% Size commands other than \cmd{\footnotesize}--\cmd{\normalsize} are
% not intended for typesetting document structures more complex
% than paragraphs.
% Therefore, their definitions do not contain specifications
% of dimension parameters for list environments or displayed equations.
% \item

% Baselineskips above 10pt are set to somewhat rounded pt sizes
% around 1.2~times the text size.
% \end{itemize}
% \end{macro}
% \end{macro}
%
% \subsection{Math Size Options}
% Consider the declarations in \LaTeXe's \fln{fontdef.dtx}:
% \begin{quote}
%\begin{verbatim}
%\DeclareMathSizes{\@xpt}{\@xpt}{7}{5}
%\DeclareMathSizes{\@xipt}{\@xipt}{8}{6}
%\DeclareMathSizes{\@xiipt}{\@xiipt}{8}{6}
%\DeclareMathSizes{\@xivpt}{\@xivpt}{\@xpt}{7}
%\DeclareMathSizes{\@xviipt}{\@xviipt}{\@xiipt}{\@xpt}
%\DeclareMathSizes{\@xxpt}{\@xxpt}{\@xivpt}{\@xiipt}
%\DeclareMathSizes{\@xxvpt}{\@xxvpt}{\@xxpt}{\@xviipt}
%\end{verbatim}
% \end{quote}
% The script and scriptscript sizes for |\@xxvpt| are one magstep
% bigger than the sizes extrapolated from the context.
% This seems to be an error. And in fact, fractions like $\frac{X}{Y}$
% placed in 25pt text strech the baseline skip, whereas this does not
% happen at lower sizes.
%
% This will be fixed when given the option \opt{normalscripts}:
% \begin{macrocode}
\DeclareOption{normalscripts}{
\DeclareMathSizes{\@xxvpt}{\@xxvpt}{\@xviipt}{\@xivpt}}
% \end{macrocode}
%
% In any case, declare math sizes for the new point sizes.
% \begin{macrocode}
\DeclareMathSizes{\@xxxpt}{\@xxxpt}{\@xxpt}{\@xviipt}
\DeclareMathSizes{\@xxxvipt}{\@xxxvipt}{\@xxvpt}{\@xxpt}
% \end{macrocode}
%
% There remains a one-magstep ratio between the script and scriptscript
% sizes for text sizes above |\@xivpt|, whereas for text sizes between
% |\@xpt| and |\@xivpt|, approximately two magsteps are taken.
% An option is defined for applying the two-magsteps rule to text sizes
% above |\@xivpt|, including the new |\@xxxpt| and |\@xxxvipt| sizes.
% \begin{macrocode}
\DeclareOption{smallscripts}{

%
% \subsection{\fntec\ Font Declaration Patch}
% \begin{macro}{\UndeclareFontFamily}
% |\UndeclareFontFamily|\marg{ENC}\marg{family} makes \NFSS\ forget
% the font information for the font family \meta{family} with encoding
% \meta{ENC} and thus causes the corresponding font declaration file
% (\fln{\meta{enc}\meta{family}.fd}) to be reloaded on demand.
% \begin{macrocode}
\newcommand\UndeclareFontFamily[2]{%
\global\expandafter\let\csname#1+#2\endcsname\relax}
% \end{macrocode}
% \end{macro}
%
% The \fntec\ font declaration patch is an optional bug fix,
% and possibly obsolete.
% \begin{macrocode}
\DeclareOption{ecpatch}{
\typeout
{*** Using EC font declaration patch for pre-1998 LaTeX2e releases ***}
% \end{macrocode}
%
% \begin{macro}{\EC@family}
% Declaration of font families from the \fntec\ or the previously

% It is defined in the relevant font definition files by means of
% \cmd{\providecommand}.
% Hence, predefining this macro will override the definition given in the
% \fln{fd} files.
% Now take the original definition and complete the size specification
% with 29.86pt and 35.83pt entries.
% Since \cmd{\nfss@catcodes} have not been activated, white space in the
% \cmd{\DeclareFontShape} call must be avoided.
% \begin{macrocode}
\def\EC@family#1#2#3#4#5{%
\DeclareFontShape{#1}{#2}{#3}{#4}{%

% \end{macro}
%
% Now undeclare font families that are usually mapped
% to \fntec\ or \fntdc\ fonts.
% On demand, they will be redeclared under control of the predefined

\UndeclareFontFamily{T1}{cmfr}
% \end{macrocode}
% The patch is now complete.
% \begin{macrocode}
}

%% and the 12pt option does not provide a command for 9pt.
%% The 11pt option fills both gaps, but misses the extremes 35.83pt and 5pt.
%% Therefore, a shorthand for lower-level size switches is provided.
%% E.g. \Size{20.74}{25} selects a 20.74pt font size with 25pt baselineskip.
