+%
+% This file contains the implementation for using units in labels.
+%
+% Default the unit setting system isn't used, It is thus required to use the key "use units".
+%
+% Programming Structure:
+%
+% 1. All associated keys are first set. This includes some prefix values of the unit system.
+% In example one can redefine prefix and postfix such that units are shown on a per-user setting.
+%
+% 2. The other main thing is scaling of the dimension. If one uses units one might not
+% have scaled the data. For this the keys "scaled <axis> ticks" are used at a base 10.
+% Currently it is not provided to scale in other bases.
+% FIXME Adding of other bases.
+%
+% 3. Some predefined SI prefixes are specified which should minimize mistakes.
+% For example the key "change <axis> base,<axis> SI prefix=kilo" allows the
+% <axis> to be rescaled according to the above at base 10 with a factor of -3 and sets the
+% unit prefix to "k".
+% FIXME Adding other basis systems than SI. For example the addition of CGS units.

+% Sorts array '#1' using N log N time.
+%
+% The sort key is provided as argument in
+% /pgfplots/array/iflessthan/.code args={#1#2#3#4}, see above.
+%
+% Remarks:
+% - the sorting algorithm is a sub-optimal mergesort currently -
+% but it has runtime N log N.
+% - As usual, it is very difficult to move the final result out of the
+% current scope. The initial configuration allocates a *global* copy of #1
+% to carry results out of one TeX group. This means that memory will NEVER be freed.
+% I don't see a general N log N alternative for doing so (short of discarding
+% the scopes for local groups).
+% BUT:
+% you can redefine the code key pair
+% |/pgfplots/array/unscope pre|
+% and
+% |/pgfplots/array/unscope post|
+% to define your own routine which may benefit from special needs of
+% your application. The |... pre| command is invoked JUST before the
+% \endgroup and the |... post| JUST after the |\endgroup|.

+% IMPLEMENTATION NOTES:
+% I allocate an array which provides storage capacity and two pointers
+% (indices) into that array.
+%
+% The deque is stored as
+% - an array: \csname pgfpldq@<name>\endcsname
+% - the pointers:
+% \csname pgfpldq@<name>@beg\endcsname
+% \csname pgfpldq@<name>@end\endcsname (one after the end)
+%
+% ATTENTION: <name> may NOT be a control sequence!
+% this is in contrast to my other container structures.
+
+
+% Allocates a new, empty deque #1.
+%
+% #1 the name of a deque (NO control sequence!)
+% #2 is an integer denoting the maximum capacity. For now, this
+% capacity is fixed afterwards and denotes the maximum number of
+% entries.

+% Set a key to a value
+%
+% #1 = key
+% #2 = tokens
+%
+% Description:
+%
+% This command sets the key to the given tokens. The tokens are stored as
+% is and can even contain things like #9.
+%
+% Keys are organized hierarchically using something similar to Unix
+% paths. Thus, a typically key might be called "/tikz/length" or
+% "/tikz/length dimension/.@cmd". Some keys starting with a dot are
+% special, so they should not be used as normal key names (they are
+% similar to Unix files starting with a dot -- you can use them, but
+% be careful).
+%
+% Keys are always local to the current TeX group.
+%
+% Example:
+%
+% \pgfkeyssetvalue{/tikz/length}{2cm-3cm}
+% \pgfkeyssetvalue{/algo/swap}{{#2}{#1}}
+
+\long\def\pgfkeyssetvalue#1#2{%
+ \pgfkeys@temptoks{#2}\expandafter\edef\csname pgfk@#1\endcsname{\the\pgfkeys@temptoks}%
+}
+
+
+
+% Add text to a key at the end
+%
+% #1 = key
+% #2 = a value to be added at the beginning
+% #3 = a value to be added at the end
+%
+% Description:
+%
+% This command adds #2 to the definition of the key. The key should
+% have been set previously using \pgfkeyssetvalue.
+%
+% Example:
+%
+% \pgfkeysaddvalue{/tikz/length}{}{-3cm}
+
+\long\def\pgfkeysaddvalue#1#2#3{%
+ {%
+ \toks0{#2}%
+ \pgfkeysifdefined{#1}

+ {\pgfkeys@temptoks{}}%
+ \toks1{#3}%
+ \xdef\pgfkeys@global@temp{\the\toks0 \the\pgfkeys@temptoks \the\toks1}% believe or don't: the spaces are important

+
+
+
+% Makes a key equal a given code
+%
+% #1 = key
+% #2 = a code name
+%
+% Description:
+%
+% This command executes a \let command so that a key gets the same
+% value as the parameter #2.
+%
+% Keys are always local to the current TeX group.
+%
+% Example:
+%
+% \pgfkeyslet{/algo/swap}{\myswap}
+
+\def\pgfkeyslet#1#2{%
+ \expandafter\let\csname pgfk@#1\endcsname#2%
+}
+
+
+% Retrieve the code stored in a key into a code
+%
+% #1 = key
+% #2 = code
+%
+% Description:
+%
+% This command will set #2 to "point" to the value stored in the key.
+%
+% Example:
+%
+% \pgfkeysgetvalue{/tikz/swap}{\myswap}
+
+\def\pgfkeysgetvalue#1#2{\expandafter\let\expandafter#2\csname pgfk@#1\endcsname}
+
+
+
+% Retrieve the value stored in a key
+%
+% #1 = key
+%
+% Description:
+%
+% This command will expand to the value stored in the key. The key
+% should previously have been set using \pgfkeyasetkey or \pgfkeyslet.
+%
+% Example:
+%
+% The length is \pgfkeysvalue{/tikz/length}.
+
+\def\pgfkeysvalueof#1{\csname pgfk@#1\endcsname}
+
+
+
+% If for testing whether a key exists
+%
+% #1 = key
+% #2 = if-case
+% #3 = else-case
+%
+% Description:
+%
+% This if will be executed if the key exists. In eTeX mode this works
+% like a normal if, in normal TeX mode you need to provide an \else.
+%
+% Example:
+%
+% \pgfkeysifdefined{/tikz/length}{key exists}{does not exist}
+
+\long\def\pgfkeysifdefined#1#2#3{\pgfkeys@ifcsname pgfk@#1\endcsname#2\else#3\fi}
+
+% Tests whether a key is assignable. For standard keys which just
+% store their value, this is identical to \pgfkeysifdefined.
+%
+% But \pgfkeysifassignable is true for command keys as well (but not
+% for handled keys).

+% Execute settings
+%
+% #1 = list of settings
+%
+% Description:
+%
+% The list of settings should contain comma-separated settings. Each
+% setting has the following form:
+%
+% /path/key=value
+%
+% The parts "/path/" and "=value" are optional. When the path is not
+% specified, the value of the token register "\pgfkeypath" is used. If
+% "=value" is missing, the value of the setting "/path/key/.@def" is used
+% instead. If this key is set to "\pgfvaluerequired", the key
+% "/errors/value required/.@cmd" is executed. Theis error handler,
+% like all other error handlers, will get the current key as its first
+% parameter (unexpanded) and the current value as its second value
+% (also unexpanded).
+%
+% Any spaces at the beginning and at the end and around the
+% equals-sign are removed. The key with the complete path is set to
+% the code \pgfcurrentkey.
+%
+% The setting is then processed according to the following rules:
+%
+% 1) If the key /path/key/.@cmd" is present, its code is executed
+% with the value computed above, followed by \pgfeov (end of
+% value). So, to handle
+%
+% "/stuff/height= 1.5 ,"
+%
+% /stuff/height/.@cmd should be set to some code, that can
+% handle the parameter
+%
+% "1.5\pgfeov"
+%
+% For instance, saying
+%
+% \pgfkeys{/stuff/height/.@cmd}{#1\pgfeov}{\def\myheight{#1}}
+%
+% will do nicely.
+%
+% 2) Otherwise, if the key /path/key is present, this key is
+% set to the value computed above.
+%
+% 3) Otherwise, if the key /handlers/key/.@cmd is present, it is executed
+% with the same parameters as in 1). Additionally, the
+% token register \pgfcurrentkeypath will be set to "/path/" and the
+% macor \pgfcurrentkeywithoutpath to "key". So, in the above
+% example if neither "/stuff/height/.@cmd" nor
+% "/stuff/height" is present, but "/handlers/height" is,
+% then "/handlers/height" is executed with the parameters:
+%
+% "1.5\pgfeov"
+%
+% and \pgfcurrentkey is set to "/stuff/height" and \pgfcurrentkeypath
+% is set to "/stuff/" and \pgfcurrentkeywithoutpath to "height".
+%
+% 4) Otherwise, if the key "/path/.unknown/.@cmd" is present, its code is
+% executed with the same parameters as in 3).
+%
+% 5) Otherwise, the key "/handlers/.unknown/.@cmd" is executed with the same
+% parameters as in 1).
+%
+% After all settings have been processed, the value of the token
+% register \pgfdefaultkeypath is set to its original value. Thus, any local
+% change of this token register has no effect outside the call.
+%
+% Example:
+%
+% \pgfkeys{/tikz/.is family}
+% \pgfkeys{/tikz/line width/.cd,
+% .def=\pgfsetlinewidth{##1},
+% .set default=.4pt}
+% \pgfkeys{tikz,line width=1pt}

+% Quickly set keys
+%
+% #1 = default path
+% #2 = key-value pairs
+%
+% Desscription:
+%
+% This command starts the execution with the default path set to
+% #1. This command should only be used when speed is important (like
+% in a heavily used macro like \tikzset). Normally, keys should be
+% used to set the path. Note that if #1 equals /, then \pgfkeys will
+% actually be quicker!
+%
+% Example:
+%
+% \pgfqkeys{/tikz}{myother length/.code=\def\myotherlength{#1}\pgfkeysalso{length=#1}}
+
+\def\pgfqkeys{\expandafter\pgfkeys@@qset\expandafter{\pgfkeysdefaultpath}}%
+\long\def\pgfkeys@@qset#1#2#3{\def\pgfkeysdefaultpath{#2/}\pgfkeys@parse#3,\pgfkeys@mainstop\def\pgfkeysdefaultpath{#1}}
+
+
+% Sets keys while setting keys
+%
+% #1 = key-value pairs
+%
+% Desscription:
+%
+% This code may only be called inside the code that is executed for a
+% key. The #1 should be a list of settings pairs. They will be executed
+% as if they had been given as the argument to the \pgfkeys command.
+%
+% Example:
+%
+% \pgfkeys{tikz,myother length/.code=\def\myotherlength{#1}\pgfkeysalso{length=#1}}
+
+\long\def\pgfkeysalso#1{\pgfkeys@parse#1,\pgfkeys@mainstop}
+
+
+
+% Quickly sets keys while setting keys
+%
+% #1 = default path
+% #2 = key-value pairs
+%
+% Desscription:
+%
+% This command executes #2 with the default path set to #1. This
+% command will cause chaos if used incorrectly. The only safe
+% place to use it instead of \pgfkeys is at the beginning of a TeX group.
+%
+% Example:
+%
+% \begingroup
+% \pgfqkeysalso{/tikz}{myother length/.code=\def\myotherlength{#1}\pgfkeysalso{length=#1}}
+
+\long\def\pgfqkeysalso#1#2{\def\pgfkeysdefaultpath{#1/}\pgfkeys@parse#2,\pgfkeys@mainstop}
+
+
+
+
+% Now setup the default handelers and keys:
+
+% Define a key macro with one argument (\def or \edef)
+%
+% #1 = key
+% #2 = code
+%
+% Description:
+%
+% This command will setup things so the key/.@cmd contains a macro
+% that takes one parameter and has #2 as its code.
+%
+% Example:
+%
+% \pgfkeysdef{/my key}{\show#1}
+
+\long\def\pgfkeysdef#1#2{%
+ \long\def\pgfkeys@temp##1\pgfeov{#2}%

+
+
+% Define a key macro with mutliple arguments (\def or \edef)
+%
+% #1 = key
+% #2 = argument pattern
+% #2 = code
+%
+% Description:
+%
+% This command will setup things so the key/.@cmd contains a macro
+% that takes #2 as its parameter pattern and has #3 as its code.
+%
+% Example:
+%
+% \pgfkeysdefargs{/swap}{#1#2}{#2#1}

+% 2.1 perhaps insert \pgfmanualpdflabel{<label>}{} where needed.

+% 3. Verify that the |...| commands occuring in situations where catcodes can't
+% be changed (footnotes or macro arguments) work as expected.
+%
+% 4. Consider telling the pretty printer that several control sequences
+% have arguments which are options (see below for the predefined list).

+% 5. @Christian: consider extensions of the parser such that it identifies path commands (at least partially)

+% This file provides an interface to the
+% pgfmanual.prettyprint.code.tex thing -- it allows to
+% *generate pdf crossrefs inside of codeexamples automatically*
+% without any user input.
+%
+% Thus, you write
+% \begin{codeexample}[]
+% \begin{tikzpicture}[options]
+% \end{tikzpicture}
+% \end{codeexample}
+% and pdf cross references to the definitions of 'tikzpicture'
+% and any options will be generated automatically.
+%
+% Furthermore, pdf cross references will be generated for everything
+% within vertical bars, |....|.
+%
+%
+%
+%
+%
+% The only necessary thing is that \pgfmanualpdflabel has been called
+% for every (fully qualified) key, control sequence, environment or
+% whatever.

+% Collects arguments inside of a token list, dealing with nested
+% catcode-12-braces.
+%
+% #1: is the NUMBER of arguments to collect.
+% #2: is TeX code which shall be invoked after
+% \pgfmanualprettyprinterhandlecollectedargs has been invoked (see
+% below).
+%
+% PRECONDITION:
+% there is a large token list following
+% \pgfmanualprettyprintercollectargcount with balanced braces. The braces
+% have \catcode 12.
+% POSTCONDITION:
+% 1. the arguments will be collected as
+% '<result> := {<first arg>}{<second arg>}',
+% 2.1 the macro \pgfmanualprettyprinternumcollectedargs will contain
+% the *actual* number of *completely* collected arguments,
+% 2.2 the if \ifpgfmanualprettyprinterarghasunmatchedbraces will be
+% set to \c true if the last found argument had an unmatched brace,
+% 3. then, \pgfmanualprettyprinterhandlecollectedargs{<result>} will be
+% invoked. Just define \pgfmanualprettyprinterhandlecollectedargs
+% properly.
+% Afterwards, #2 will be invoked to recover from the argument
+% collection.
+%
+%
+% Example:
+% \pgfmanualprettyprintercollectargcount{2}{\donnextstep}
+% {_12 first argument }_12 {_12 second argument }_12 next tokens%
+%
+% will result in the expansion
+% \pgfmanualprettyprinterhandlecollectedargs{{_1 first argument }_2 {_1 second argument }_2 }
+% \donnextstep
+% next tokens
+%
+%
+%
+% ATTENTION:
+% \pgfmanualprettyprinterhandlecollectedargs will be invoked with a SINGLE
+% argument. The argument as such will contain extra braces, one pair
+% of braces for each of the #1 arguments. These braces will have
+% catcode 1 and 2, i.e. they can *really* be used in TeX. Thus, the
+% finish routine will be invoked with
+% \pgfmanualprettyprinterhandlecollectedargs{{<arg>}}
+% for one argument and with
+% \pgfmanualprettyprinterhandlecollectedargs{{<first arg>}{<second arg>}}
+% for two and more arguments. Note the extra set of braces for one
+% arg.
+% It might happen that not all arguments have been found if
+% end-of-input occured before. The
+% \pgfmanualprettyprinterhandlecollectedargs routine has to check
+% this using the macro \pgfmanualprettyprinternumcollectedargs which
+% contains the actual number of collected args.
+%
+% @remark This macro checks for the end-of-input indicator, \pgfmanual@EOI. In case it encounters
+% \pgfmanual@EOI, it
+% 1. stops collecting, leaving the \pgfmanual@EOI as next token to be read,
+% 2. sets \ifpgfmanualprettyprinterarghasunmatchedbraces to \iftrue if necessary,
+% 3. assigns \pgfmanualprettyprinternumcollectedargs
+% 4. invokes the finish routine.
+% The \pgfmanual@EOI needs to be collected by following routines in
+% this case. You can also use \pgfutil@ifnextchar\pgfmanual@EOI{}{} in
+% following routines to check for \pgfmanual@EOI.

+% ******************************
+%
+%
+% This file provides a high-level automatic export feature for tikz pictures.
+% It allows to export EACH SINGLE FIGURE into a separate PDF.
+%
+% The simplest way is to use the 'convert with system call' option; it simply converts every figure using the write18 method. If that is not possible, a list of figure file names is generated and you need to generate these figures manually (or with a script).
+%
+%
+% It replaces \tikzpicture/ \endtikzpicture and \tikz and invokes \beginpgfgraphicnamed ... \endpgfgraphicnamed
+% commands if necessary.
+
+% handle with extreme care and only in small, local groups:

+% This file provides a high-level automatic export feature for tikz pictures.

+%
+% The simplest way is to use

+% it simply converts every figure using the write18 method. If that is not possible,
+% you need to reconfigure \tikzexternalize: it can generate a list of figure file names
+% and you need to generate these figures manually (or with a script).
+%

-% for every available surface, a macro '\pgfplots@surfenabled@CCC'
-% is defined to be either '0' or '1'.
+% - for every available surface, a macro '\pgfplots@surfviewdepth@CCC'
+% is defined to be either 'f' (foreground) or 'b' (background).
% Thus, we don't have real TeX booleans, "only" those one-character
% strings.
+% There are high-level routines to check these flags.
+% - every tick label position will be initialised, i.e. the macros
+% \pgfplots@[xyz]ticklabelaxisspec
+% will be initialised.
%
% ABOUT THE ALGORITHM:
-% I find it really hard to decide exactly which surfaces shall be drawn. After
-% all, PGF is 2D and notions like "above" are not possible.
-% So, I resorted to an heuristic approach which will (hopefully) prove
-% to be a good idea:
+% Given \pgfplots@view@dir@threedim@[xyz], we know the view direction (in 3D!).
+% Now, we compute the scalar products <n,(1,0,0)'> <n,(0,1,0)'> and
+% <n,(0,0,1)'> between the view direction n and the unit vectors in 3D
+% space. Of course, these scalar products are just specific components
+% of n. Using the sign of the scalar product, we know whether n points
+% roughly into the same or the opposite direction of each unit vector
+% and we can deduce foreground and background side surfaces of the
+% unit cube. The idea is: foreground surfaces won't be drawn, only
+% background surfaces.
%
-% ASSUMPTION:
-% 1. We have a right-handed-coordinate system. The heuristics here
-% WILL fail in every other case.
-% 2. The z-axis points to the top of the paper.
-% Again, the heuristics WILL fail if that is not the case.
-% Both assumptions happen to be reasonable for most cases.
-% I will have to think about those cases where they are not
-% reasonable.
+% Given this knowledge, we can also deduce the default axes for tick
+% labels.
%
-% Now, the heuristics ONLY CHECKS THE 'y' components of the the three
-% basis vectors. Since per assumption (1.), z_y > 0, there remain only
-% a handful of cases for x_y > 0, x_y <0, y_y > 0 and y_y <0. I have
-% hard-coded good approaches for each of them below.
+% The operation is relatively fast.

+% Handles the 'every 3d description' style.
+%
+% This requires a different type of attention than any other key --
+% because all other keys are set in a context where the dimension of
+% the axis is unknown (it might be 2 or 3 dimensional).
+%
+% The idea is:
+% Call \pgfplots@BEGIN@prepare@description@styles as soon as the
+% dimension is fixed, but before any style changes of the user
+% interface are applied.
+%
+% Example:
+% \begin{axis}[xlabel style={}]
+% will be processed here. The reason: 'every 3d description' will
+% certainly use a different style for axis labels than the default 2d
+% style.
+%
+% Thus, all style changes which are relevant for 'every 3d description'
+% have NOT YET been processed (they have been appended to 'every axis').

-% Then, we use the rotated XY plane as viewport, that means

+% zvec = v * [0 0 1]' = <third column of v>
% and we define the projection onto the twodimensional surface

-% P( q ) = [ q^T xvec, q^T yvec ]'
+% spanned by 'xvec' and 'zvec' as

+
+% Declares a routine which can be used to get point meta input.
+%
+% Such a routine is invoked in a context where point coordinates are
+% processed, i.e. during 'plot coordinates', 'plot table' or the like.
+%
+% The routine is called `#1'. It consists of several methods:
+% - \csname pgfpmeta@#1@assign\endcsname{}
+% During the survey phase, this macro is expected to assign
+% \pgfplots@current@point@meta
+% This method should prepare everything which is needed to invoke
+% the postprocessors, i.e. it prepares the input for point meta
+% transformations to [0,1000] or the scatter plot things. In other
+% words: if it is a numeric input method, it should return a
+% floating point number.
+% It is allowed to return an empty string to say "there is no point
+% meta".
+% PRECONDITION for '@assign':
+% - the coordinate input method has already assigned its
+% '\pgfplots@current@point@meta' (probably as raw input string).
+% - the other input coordinates are already read.
+% POSTCONDITION for '@assign':
+% - \pgfplots@current@point@meta is ready for use:
+% - EITHER a parsed floating point number
+% - OR an empty string,
+% - OR a symbolic string (if #3=symbolic)
+% The default implementation is
+% \let\pgfplots@current@point@meta=\pgfutil@empty
+%
+% - \csname pgfpmeta@#1@issymbolic\endcsname -> expands to either '1' or '0'
+% A numeric source will be processed numerically, i.e. the final map
+% to [0,1000] will be initialised and meta limits will be updated.
+% A symbolic input routine won't be processed.
+% Default is '0'
+%
+% - \csname pgfpmeta@#1@explicitinput\endcsname -> expands to either
+% '1' or '0'. In case '1', it expects explicit input from the
+% coordinate input routines. For example, 'plot file' will look for
+% further input after the x,y,z coordinates.
+% Default is '0'
+%
+% - \csname pgfpmeta@#1@initfor\endcsname##1{....}
+% a macro used to initialise the point meta source when it is
+% selected.
+% This macro body is invoked by pgfplots when someone types
+% 'point meta=x' -> will invoke 'pgfpmeta@x@initfor{}'.
+% The first argument to initfor can be supplied by the user.
+% PRECONDITION for 'initfor':
+% - it will be invoked just before
+% '\pgfplotspointmetainputhandler' will be changed.
+% Default is to do nothing.

+%
+% - column indices,

+% The low-level tikz plot handler for 3D mesh and surface plots.
+%
+% It expects
+% a) a coordinate stream which is a linearized matrix, iterated either
+% rowwise or column wise,
+% b) the current set of options in /pgfplots/mesh/.
+%
+%
+% ATTENTION:
+% this handler is NOT as general as the others. In particular, it
+% can't be interrupted by TeX groups: every single statement,
+% starting with streamstart and ending with stream end, must be in
+% the same scope!
+%
+% As a consequence, you can't use this handler inside of (all) TikZ
+% input streams. Try it out. It will work in pgfplots, however.
+%
+% Furthermore, it relies on a couple of pgfplots macros. This may
+% change in future versions.
+% It relies on:
+% - \ifpgfplots@curplot@threedim
+% - \pgfplots@current@point@meta
+% -> it also invokes \pgfplots@perpointmeta@preparetrafo and its
+% @APPLY counterpart which checks for
+% - \pgfplots@metamax
+% If you use it outside of pgfplots, use
+% \global\let\pgfplots@metamax=\pgfutil@empty
+% This is can be used without an initialised
+% pgfplots axes - as long as \pgfplots@current@point@meta is in
+% the range [0,1000].
+% - for the case 'shader=interp', a bounding box must be established
+% before the plot is finished. This must be done using
+% \def\pgfplotspointbbupperright{\pgfqpointxyz{2}{2}{0.9}}
+% \def\pgfplotspointbblowerleft {\pgfqpointxyz{0}{0}{0.1}}
+% or something like that.
+%
+% Besides these internals, it also relies on all public /pgfplots
+% configuration keys related to mesh/surface plots.
+%
+% Please note that the 'z buffer' feature will not work without
+% pgfplots (especially the z buffer=sort feature).
+%

-% Draws tick labels at the A positions of the currently set oriented
+% Draws tick labels at the positions of the currently set oriented
% surface.
%
% Tick positions are taken out of the already precomputed list
% \pgfplots@prepared@tick@positions@major@...
%
+% For 2D axes, this task is relatively simple:
+% we iterate through every prepared major tick position and place a
+% tick label. Open points, however, are the question whether to use
+% the RIGHT or the LEFT axis line on the current oriented surface:
+%
+% direction 'b' (second oriented)
+% |-------------------------|
+% | |
+% | |
+% | |direction 'a' (first oriented)
+% | |
+% | |
+% | |
+% |-------------------------|
+% Left Right
+%
+% Given the axis line which shall contain the labels, we have to
+% decide how to align the tick label nodes: on the left or on the
+% right? Of course, we want to align them such that they are "outside"
+% of the figure! That's simple as well: "Left axis line => outside
+% means left", "Right axis line => outside means right".
+%
+% That's all, basically.
+%
+% For 3D axes, all these points are basically ... the same!
+% Now it can happen that the current oriented surface shall
+% not contain ANY tick label. In that case, we do nothing.
+% Furthermore, the "outside" direction (i.e. the anchoring of the
+% label nodes) is a little bit more difficult.
+%

+% This here does the main work for any tick label ANCHORING.
+%
+% FIXME : the new 'near ticklabel' anchors are now the default method
+% to place tick labels.
+%
+% This feature here can be used to disable this anchoring, i.e. set
+% 'ticklabel anchor=tikz' to use a stupid heuristics.
+%
+% There are actually two choices:
+% Choice 1: near ticklabel
+% This choice places tick labels fully automatic outside of the
+% figure, all on a line which is parallel to the axis which
+% contains the corresponding tick labels.
+%
+% Since we are currently working on a restricted surface, we have
+% three direction related to that surface:
+% 'a': this is the direction in which tick positions are known.
+% 'b': the 'orthogonal' axis to 'a' which is also in the surface.
+% 'n': the surface normal.
+% Now, the idea for tick labels is to place them at
+% SCALE_b * b + SCALE_n * n,
+% where the SCALE_[bn] numbers are choosen such that the label is
+% outside of the axis.
+%
+% The offset is simply added to the transformation matrix (as a
+% shift).
+%
+% Choice 2: tikz.
+% This is more or less a backwards compatibility feature. It does
+% not change the transformation matrix. It simply sets the 'at' key
+% of each node to the tick position and prepares the correct anchors
+% for the TikZ '\node' commands.
+% That's all here.
+%
+% PRECONDITION:
+% - called inside of \pgfplots@drawticklabels@onorientedsurf@
+% POSTCONDITION:
+% - defines
+% - \pgfplots@tickposchoicea
+% if called, sets keys such that tick labels are RIGHT (TOP) of

+% The lowlevel call for surface shadings. It uses a pattern type 2
+% dictionary as fill color and has thus several things to do. This is
+% a little bit more complicated than using the '/sh' operator (as
+% other pgf shadings do): the surface shading must be positioned
+% exactly at the requested coordinates, otherwise it is quite useless.
+%
+% Since shadings are *not* affected by changes in the canvas
+% transformation matrix (shifts, rotations etc), it is necessary to
+% pack the shading into a separate xform object which is then rotated
+% and translated correctly.
+%
+% There is just one more transformation necessary: the shift inside of
+% the xform. This shift is done using changes in the canvas
+% transformation matrix and it is UNDONE in the /Matrix argument of
+% the pattern dictionary. This last step can't be done with the /sh
+% operator which is why I am using pattern dictionaries.

+% An implementation for signed integers which maps the signed integer linearly into
+% the unsigned data range before it proceeds.
+%
+% The idea is thus, to first introduce a linear mapping
+%
+% phi : [- smallest_possible, +largest_possible ] -> [0, 256^bytes-1 ]
+%
+% A signed integer in TeX is in [ - (2^31-1), 2^31-1 ].
+% Thus, we should map
+%
+% phi : [ -(2^31-1), 2^31-1 ] -> [ 0, 2^32-1 ].
+%
+% A simpler case is to employ the symmetry in TeX's registers and
+% leave one out, i.e. to map to 2^32-2:
+%
+% phi : [ -(2^31-1), 2^31-1 ] -> [ 0, 2^32-2 ].
+%
+% Then,
+%
+% phi(x) = ( x + 2^31 -1 ) / (2^31-1 + 2^31-1) * (2^32-2) = x+ 2^31-1.
+%
+% The same map phi(x) = x + 2^31 -1 with target space [0, 2^32-1 ]
+% could be realized with the input space [- (2^31-1), 2^31 ].
+%
+% I am using this encoding procedure, phi(x) = x + 2^31 -1.
+%
+% As a consequence, the binary pattern FF FF FF FF does never occur as
+% result of the mapping.
+%
+% To invert the mapping (i.e. to decode the result), set up the unique
+% linear map
+%
+% psi : [ 0, 2^32-1 ] -> [ -(2^31-1), 2^31 ].
+%
+% Then, psi( phi(x) ) = x and the decoding procedure is correct.
+%
+% This doesn't need TeX register arithmetics on the whole range.
+%
+% REMARK: the whole operation does also work if bytes<4 (i.e. we have
+% less than 32 bits in the target range). In this case, the mapping is
+% phi : [ -(2^31-1), 2^31-1 ] -> [ 0, 2^{8*bytes}-1 ]
+% and a further, *lossy* quantization still will be applied. The
+% quantization step is an integer division performed in signed number
+% arithmetics (i.e. it is symmetric around 0).

+% Encodes a dimen (like 1pt or \dimen0) in binary form.
+%
+% The encoding works by mapping #1 linearly into the allowed integer
+% range using a quantization technique to respect the (possibly)
+% restricted number of bytes.
+%
+% The implementation is fast and uses only integer arithmetics.
+% It relies on \pgfplotsbinaryencodesignedmaplinearly and a scale.
+%
+% So, what we do is to setup a linear map into binary range with k
+% bytes. The range of a TeX dimen is precisely (in units of pt)
+% [ -(2^30-1) / 2^16, (2^30 -1) / 2^16 ] = [-16383.99998, 16383.99998]
+%
+% Thus, for an input dimen x, we set up the mapping
+% phi(x) = 2^16 * x * 2
+% which maps
+% phi: [ -(2^30-1) / 2^16, (2^30-1) / 2^16 ] -> [-(2^31 -2), 2^31-2].
+%
+% I simply use the \pgfplotsbinaryencodesignedmaplinearly to process
+% this further. To simplify the computation, I simply compute
+% phi_signed( phi(x) ),
+% where phi_signed denotes an application of
+% \pgfplotsbinaryencodesignedmaplinearly:
+% phi_signed( y ) = y +2^31 -1,
+% phi_signed( phi(x) ) = 2^16 * 2 * x + 2^31 - 1.
+% This is NOT a linear map to [0,2^32-1] as promised.
+% But, we can setup an inverse transformation PHI (which is linear) anyway
+% such that
+% PHI( phi_signed(phi(x)) ) = x
+% and that's all I want. Do do that, we use the unique linear decoder map
+% PHI : [ 0,2^32-1 ] -> [ -16383.999992, 16384 ].
+%
+% This is not exacty the input range of before, but using it results
+% in a proper decoder. The difference is due to the non-unique zero
+% representation in TeX's arithmetics.
+%
+%
+% REMARK: the whole operation does also work if bytes<4 (i.e. we have
+% less than 32 bits in the target range). In this case, a further
+% *lossy* quantization step is applied in phi_signed. The inverse
+% transformations are the same, however. See
+% \pgfplotsbinaryencodesignedmaplinearly for details about the
+% quantization step (or try it out).

+% - an array 'pgfpl@cm@#1' of RGB color triples,
+% - numbers 'pgfpl@cm@#1@h' and 'pgfpl@cm@#1@invh' for the mesh width
+% and inverse mesh width.
% Creates a new colormap.

+% #2 : a <color specification> as is expected for a shading spec of

+% - it supports 'rgb255' in addition to pgf,
+% - the length is not required (defaults to 1cm for the first and to
+% the last length+h for all others).
+% - the semicolons can be omitted.

+% Creates an area which is clickable. A click produces a popup which
+% contains information about the point under the cursor.
+%
+% The complete (!) context needs to be provided using key-value-pairs,
+% either in '#1' or set before invocation of \pgfplotsclickablecreate.
+%
+% This command actually creates an AcroForm which employs javascript
+% whenever it is clicked. A javascript Object is created which
+% represents the context (axis limits and options). This javascript
+% object is available at runtime.
+%
+% @remark This method is public and it is NOT restricted to pgfplots.
+% The pgfplots hook simply initialises the required key-value-pairs in
+% '#1'.
+% @remark This method does not draw anything. It initialises only a
+% clickable area and javascript code.
+%
+% The required key-value-pairs are documented in the pdf-manual or can
+% be seen above.
+%
+% @attention Complete key-value validation is NOT performed here. It
+% can happen that invalid options will produce javascript bugs when
+% opened with Acrobat Reader. Use the javascript console to find them.

-% Creates an area which is clickable. A click produces a popup which
-% contains information about the point under the cursor.
-%
-% The complete (!) context needs to be provided using key-value-pairs,
-% either in '#1' or set before invocation of \pgfplotsclickablecreate.
-%
-% This command actually creates an AcroForm which employs javascript
-% whenever it is clicked. A javascript Object is created which
-% represents the context (axis limits and options). This javascript
-% object is available at runtime.
-%
-% @remark This method is public and it is NOT restricted to pgfplots.
-% The pgfplots hook simply initialises the required key-value-pairs in
-% '#1'.
-% @remark This method does not draw anything. It initialises only a
-% clickable area and javascript code.
-%
-% The required key-value-pairs are documented in the pdf-manual or can
-% be seen above.
-%
-% @attention Complete key-value validation is NOT performed here. It
-% can happen that invalid options will produce javascript bugs when
-% opened with Acrobat Reader. Use the javascript console to find them.
