% ******************************
%
% \iframe sets isomorphous frames. Isomorphous frames are stretchable
% neither horizontally nor vertically; they are only scalable by the
% same factor in all directions.
%
% The syntax of \iframe is the following:
% \iframe IFRAME (HPOS, VPOS) WIDTH MINHEIGHT HSTRETCH VSTRETCH
%         UNITHEIGHT:CONTENTS
%
% *  IFRAME should be a macro that draws the frame in a picture environment,
%    assuming that the unitlength has been set equal to the height of the
%    area which is to contain the frame's contents.
%
% *  HPOS and VPOS determine the position of the frame's contents within
%    the frame; they are given by the distance between the frame's lower
%    left corner and the lower left corner of the contents area.
%    HPOS and VPOS should be in units, assuming that the unitlength is
%    the height of the contents area.
%
% *  WIDTH is 1000 times the width/height ratio of the frame's contents area.
%
% *  MINHEIGHT is the minimum height of the contents.
%
% *  HSTRETCH should be a macro that takes two arguments: a dimension
%    HSIZE and a box number BOX. HSTRETCH reads the box and enlarges
%    it to have width HSIZE. The following HSTRETCH macros are defined:
%    -  \ifrl  (sets the box flushed left)
%    -  \ifrr  (sets the box flushed right)
%    -  \ifrch (sets the box centered)
%    VSTRETCH does the similar thing for the vertical dimension:
%    -  \ifrt  (sets the box flushed up by increasing its depth)
%    -  \ifrb  (sets the box flushed down by increasing its height)
%    -  \ifrcv (sets the box `centerd' by increasing depth and height by
%              the same amount)
%
% *  UNITHEIGHT (optional) is an identifier (just some string of alphabetic
%    characters) which identifies the so-called unit height. Every time
%    a frame is set, the smaller of the contents height and the unit height
%    is set to the larger one. After compiling the entire file, the unit
%    height will have been increased to fit the largest contents which have
%    been framed with it. The unit height is then saved, and reloaded the
%    next time the file is compiled. All frames using that unit height
%    will be set to the same size then, which is determined by the largest
%    box which should fit in it.
%
% *  CONTENTS is what is to be framed.

% of the squared contents, causing the circle to stick out.

% ******************************
% �     STRETCHABLE FRAMES     �
% ******************************
%
% Stretchable frames consist of four parts: two side parts (left and right)
% and two ledger parts (top and bottom).
% The side and ledger parts are macros which take (unfortunately) a lot
% of arguments: eight to be exact. The first is the box in which the side or
% ledger part is to be set. The second is the basic width of the box to
% be framed. Imagine this is the top border of the box to be framed:
% ------*-------------------------*---.
%   #3                             #4
% The asterisks specify the part of the border that has to be spanned by
% the top ledger of the frame. The total length of this border should be
% given by the second argument of the macro. The third and the fourth
% argument should specify the distances between the ends and the
% fastening points (indicated by the asterisks). Of course these distances
% are usually zero. After the ledger has been fastened the fastening
% points should be moved, because the fastening points are considered
% to be the corners of the framed box and could be needed to position
% the side parts of the frame. Imagine a strange ledger like this one:
%
%   *################
%     #################################*
%       ###########################
% ------o-------------------------o---
% The asterisks indicate the new fastening points. The position of the left
% fastening point should be stored in the dimensions identified by argument
% five and seven. The fifth argument should be set to the horizontal distance
% from the left end of the framed box border to the new left fastening point.
% The seventh argument should be set to the vertical distance between the
% framed box border and the fastening point. This distance should be
% negative if the new fastening point is outside the box, which it usually
% is. Similarly, the position of the right fastening point should be
% stored in the sixth and eighth argument. Note that if a new fastening
% point is positioned to the left or right of the framed box, its
% horizontal coordinate should be set negative. For example: in the
% above figure the right fastening point sticks out horizontally, so
% the sixth argument should be set to a negative value.
%
% For left part macros, swap left en top, and swap right and bottom in
% the above explanation. For bottom part macros, mirror the above story
% in the horizontal axis. For right part macros, mirror the left part
% explanation in the vertical axis.
%
% The basic syntax of a stretchable frame call is:
%    \sframe LEFTSIDE TOPLEDGER RIGHTSIDE BOTTOMLEDGER -HORIZALIGN |VERTALIGN
%            CONTENTS
% LEFTSIDE to BOTTOMLEDGER are as explained above.
% -HORIZALIGN and |VERTALIGN are optional. If specified the aligns have
% the following syntax:
%            [MINDIM] STRETCH UNITDIM:
% where [MINDIM] and UNITDIM are optional (however, it does not make sense
% to omit both of them). The effect of specifying aligns is similar to
% the effect of specifying minimal heights, stretches and unit heights for
% an \iframe. The difference is that \iframe aligns work in horizontal and
% vertical direction simultaneously, while \sframe offers independent
% handling of the horizontal and vertical directions.
%
% \sfrsrule is a predefined macro which can be used as a left or right
% side. It draws a vertical rule with thickness \fboxrule.
% \sfrlrule does the similar thing horizontally and can be used as a
% top or bottom ledger. Note however that
%    \sframe\sfrsrule\sfrlrule\sfrsrule\sfrlrule{stuff}
% does _not_ draw a proper box around stuff. There will be no corners!
% The solution is to divide the frame constructing process in phases.
% The first phase is drawing the side parts. The second phase is
% drawing the ledger parts, taking in account the width contributed
% by the already drawn side parts. Up to four phases can be used.
% The phases can be specified simply by typing the phase number
% between brackets just before each part, for example:
%    \sframe [1]\sfrsrule [2]\sfrlrule [1]\sfrsrule [2]\sfrlrule {stuff}
% Each part for which no phase is specified will be drawn in phase four.
%
% To specify an empty side or ledger, specify any macro with a invalid
% phase number, e.g.: "[0]\open".
%
% There is a environment variant of \sframe: use
% \begin{sframed}... STUFF\end{sframed} instead of \sframe...{STUFF}.
