+% Path construction commands
+%
+%
+
+\def\pgfsys@moveto#1#2{\pgf@sys@fail{path constructions}}
+% This command is used to start a path at a specific point (#1bp,#2bp)
+% or to move the current point of the current path to (#1bp,#2bp)
+% without drawing anything upon stroking (the current path is
+% `interrupted').
+%
+% Here (and in the following) the coordinates are in TeX's big points
+% (bp), unless the coordinate system has been scaled. A big point is
+% 1/72 inches. Note that TeX's point pt is 1/72.27 inches.
+%
+% Example:
+%
+% \pgfsys@moveto{10}{10}
+% \pgfsys@lineto{0}{0}
+% \pgfsys@stroke
+%
+% This will draw a line from (10bp,10bp) to the origin of the picture.
+
+\def\pgfsys@lineto#1#2{\pgf@sys@fail{path constructions}}
+% Continue the current path to (#1bp,#2bp) with a line.
+
+\def\pgfsys@curveto#1#2#3#4#5#6{\pgf@sys@fail{path constructions}}
+% Continue the current path with a bezier curver to (#5bp,#6bp). The
+% control points of the curve are at (#1bp,#2bp) and (#3bp,#4bp).
+
+\def\pgfsys@rect#1#2#3#4{\pgf@sys@fail{path constructions}}
+% Append a rectangle to the current path whose lower left corner is at
+% (#1bp,#2bp) and whose width/height is given by (#3bp,#4bp).
+%
+% This command can be `mapped back' to moveto and lineto commands, but
+% it is included since pdf has a special, quick version of this command.
+
+\def\pgfsys@closepath{\pgf@sys@fail{path constructions}}
+% Close the current path. This results in joining the current point of
+% the path with the point specified by the last moveto
+% operation. Typically, this is preferable over using lineto to the
+% last point specified by a moveto, since the line starting at this
+% point and the line ending at this point will be smoothly joined by
+% closepath.
+%
+% Example:
+%
+% \pgfsys@moveto{0}{0}
+% \pgfsys@lineto{10}{10}
+% \pgfsys@lineto{0}{10}
+% \pgfsys@closepath
+% \pgfsys@stroke
+%
+% versus
+%
+% \pgfsys@moveto{0}{0}
+% \pgfsys@lineto{10}{10}
+% \pgfsys@lineto{0}{10}
+% \pgfsys@lineto{0}{0}
+% \pgfsys@stroke
+%
+% The difference between the above will be that in the second triangle
+% the corner at the origin will be wrong; it will just be the overlay
+% of two lines going in different directions, not a sharp pointed
+% corner.
+
+
+
+
+
+
+%
+%
+% Stroking and filling commands
+%
+%
+
+\def\pgfsys@stroke{\pgf@sys@fail{path usage}}
+% Stroke the current path (as if it were drawn with a pen). A number
+% of so-called graphic state parameters influence this, which can be
+% set in different ways:
+%
+% - linewidth
+% The `thickness' of the line. A width of 0 is the thinnest width
+% renderable on the device. On a high-resolution printer this may
+% become invisible and should be avoided. A good choice is 0.4pt,
+% which is the default.
+%
+% - stroke color
+% This special color is used for stroking. If it is not set, the
+% current color is used.
+%
+% - cap
+% The cap describes how the endings of lines a drawn. A round cap
+% adds a little half circle to these endings. A butt cap ends the
+% lines exactly at the end (or start) point without anything
+% added. A rectangular cap ends the lines like the butt cap, but the
+% lines protrude over the endpoint by the line thickness. (See also
+% the pdf or postscript manual). If the path has been closed, no cap
+% is drawn.
+%
+% - join
+% This describes how a bend (a join) in a path is rendered. A round
+% join draws bends using small arcs. A bevel join just draws the two
+% lines and then fills the join minimally so that it becomes
+% convex. A miter join extends the lines so that they form a single
+% sharp corner, but only up to a certain miter limit. (See the pdf
+% or postscript manual once more).
+%
+% - dash
+% The line may be dashed according to a dashing pattern.
+%
+% - clipping area
+% If a clipping area is established, only those parts of the path
+% that are inside the clipping area will be drawn.
+%
+% In addition to stroking a path, the path may also be used for
+% clipping after it has been stroked. This will happen if the
+% \pgfsys@clipnext is used prior to this command, see there for
+% details.
+
+\def\pgfsys@fill{\pgf@sys@fail{path usage}}
+% This command fills the area surrounded by the current path. If the
+% path has not yet been closed, it is closed prior to filling. The
+% path itself is not stroked. For self-intersecting paths or paths
+% consisting of multiple parts, the nonzero winding number rule is
+% used to determine whether a point is inside or outside the
+% path, except if \ifpgfsys@eorule holds -- in which case the even-odd
+% rule should be used. (See the pdf or postscript manual for details.)
+%
+% The following graphic state parameters influence the filling:
+%
+% - fill color
+% If the fill color is not especially set, the current color is
+% used.
+%
+% - clipping area
+% If a clipping area is established, only those parts of the filling
+% area that are inside the clipping area will be drawn.
+%
+% In addition to filling the path, the path will also be used for
+% clipping if \pgfsys@clipnext is used prior to this command.
+
+\def\pgfsys@fillstroke{\pgf@sys@fail{path usage}}
+% First, the path is filled, then the path is stroked. If the fill and
+% stroke colors are the same (or if they are not specified and the
+% current color is used), this yields almost the same as a
+% \pgfsys@fill. However, due to the line thickness of the stroked
+% path, the fillstroked area will be slightly larger.
+%
+% In addition to stroking and filling the path, the path will also be
+% used for clipping if \pgfsys@clipnext is used prior to this command.
+
+\def\pgfsys@clipnext{\pgf@sys@fail{path usage}}
+% This command should be issued after a path has been constructed, but
+% before it has been stroked and/or filled or discarded. When the
+% command is used, the next stroking/filling/discarding command will
+% first be executed normally. Then, afterwards, the just-used path
+% will be used for subsequent clipping. If there has already been a
+% clipping region, this region is intersected with the new clipping
+% path (the clipping cannot get bigger). The nonzero winding number
+% rule is used to determine whether a point is inside or outside the
+% clipping area or the even-odd rule, depending on whether
+% \ifpgfsys@eorule holds.
+
+\def\pgfsys@discardpath{\pgf@sys@fail{path usage}}
+% Normally, this command should `throw away' the current path.
+% However, after \pgfsys@clipnext has been called, the current path
+% should subsequently be used for clipping. See \pgfsys@clipnext for
+% details.
+
+
+
+
+
+%
+%
+% Stroking options
+%
+%
+\def\pgfsys@setlinewidth#1{\pgf@sys@fail{setting the line width}}
+% Sets the width of lines, when stroked, to #1bp.
+
+\def\pgfsys@buttcap{\pgf@sys@fail{setting the line cap}}
+% Sets the cap to a butt cap. See \pgfsys@stroke.
+
+\def\pgfsys@roundcap{\pgf@sys@fail{setting the line cap}}
+% Sets the cap to a round cap. See \pgfsys@stroke.
+
+\def\pgfsys@rectcap{\pgf@sys@fail{setting the line cap}}
+% Sets the cap to a rectangular cap. See \pgfsys@stroke.
+
+\def\pgfsys@miterjoin{\pgf@sys@fail{setting the line join}}
+% Sets the join to a miter join. See \pgfsys@stroke.
+
+\def\pgfsys@setmiterlimit#1{\pgf@sys@fail{setting the line cap}}
+% Sets the miter limit of lines to #1. See the pdf or postscript
+% documentation.
+
+\def\pgfsys@roundjoin{\pgf@sys@fail{setting the line cap}}
+% Sets the join to a round join. See \pgfsys@stroke.
+
+\def\pgfsys@beveljoin{\pgf@sys@fail{setting the line cap}}
+% Sets the join to a bevel join. See \pgfsys@stroke.
+
+\def\pgfsys@setdash#1#2{\pgf@sys@fail{setting the dashing pattern}}
+% Sets the dashing patter. #1 should be a list of lengths given in big
+% points (bp) separated by spaces. #2 should be a single value given
+% in bp.
+%
+% The list of values in #1 is used to determine the lengths of the
+% `on' phases of the dashing and of the `off' phases. For example, if
+% #1 is `3 4', then the dashing pattern is `3bp on followed by 4bp
+% off, followed by 3bp on, followed by 4bp off, and so on'. A pattern
+% of `.5 4 3 1.5' means `.5bp on, 4bp off, 3bp on, 1.5bp off, .5bp on,
+% ...'. If the number of entries is odd, the last one is used twice,
+% so `3' means `3bp on, 3bp off, 3bp on, 3bp off,...'. An empty list
+% means `always on'.
+%
+% The second argument determines the `phase' of the pattern. For
+% example, for a pattern of `3 4' and a phase of `1', the pattern
+% would start: `2bp on, 4bp off, 3bp on, 4bp off, 3bp on, 4bp off...'.
+
+

+%
+% Color stuff
+%
+%
+
+\def\pgfsys@color@rgb@stroke#1#2#3{\pgf@sys@fail{color}}
+% Sets the color used for stroking operations to the given rgb tuple
+% (numbers between 0 and 1).
+%
+% Example: Make stroked text dark red: \pgfsys@color@rgb@stroke{0.5}{0}{0}
+%
+% The special stroking color is only used if the stroking color has
+% been set since the last \pgfutil@color command. Thus, each \pgfutil@color command
+% should reset both the stroking and filling colors.
+
+\def\pgfsys@color@rgb@fill#1#2#3{\pgf@sys@fail{color}}
+% Sets the color used for filling operations to the given rgb tuple
+% (numbers between 0 and 1). This color may be different from the
+% stroking color.
+
+\def\pgfsys@color@rgb#1#2#3{\pgfsys@color@rgb@stroke{#1}{#2}{#3}\pgfsys@color@rgb@fill{#1}{#2}{#3}}
+% Sets the color used for filling and stroking operations. This is a
+% ``low-level'' version of the \pgfutil@color command. It is currently only
+% used by the plain tex version to support colors.
+
+\def\pgfsys@color@cmyk@stroke#1#2#3#4{\pgf@sys@fail{color}}
+% Sets the color used for stroking operations to the given cymk tuple
+% (numbers between 0 and 1).
+
+\def\pgfsys@color@cmyk@fill#1#2#3#4{\pgf@sys@fail{color}}

+
+\def\pgfsys@color@cmyk#1#2#3#4{\pgfsys@color@cmyk@stroke{#1}{#2}{#3}{#4}\pgfsys@color@cmyk@fill{#1}{#2}{#3}{#4}}
+% Sets the color used for filling and stroking operations.
+
+\def\pgfsys@color@cmy@stroke#1#2#3{\pgf@sys@fail{color}}
+% Sets the color used for stroking operations to the given cym tuple

+
+\def\pgfsys@color@cmy#1#2#3{\pgfsys@color@cmy@stroke{#1}{#2}{#3}\pgfsys@color@cmy@fill{#1}{#2}{#3}}
+% Sets the color used for filling and stroking operations.
+
+\def\pgfsys@color@gray@stroke#1{\pgf@sys@fail{color}}
+% Sets the color used for stroking operations to the given gray level
+% (number between 0 and 1).
+
+\def\pgfsys@color@gray@fill#1{\pgf@sys@fail{color}}

+
+\def\pgfsys@color@gray#1{\pgfsys@color@gray@stroke{#1}\pgfsys@color@gray@fill{#1}}
+% Sets the color used for filling and stroking operations.
+
+\newif\ifpgfsys@color@reset@inorder
+% This if decides whether the color resetting of the
+% \pgfsys@color@reset command may assume that all color commands are
+% given ``in order.'' This means that this command will not be called,
+% say, at the beginning of a box that is later inserted at a point
+% where a fill color was actively set. This may allow the command to
+% produce more compact code when it ``knows'' that no special fill or
+% stroke color has been set.
+\pgfsys@color@reset@inordertrue
+
+
+\def\pgfsys@color@reset{}
+% This command will be called when the \pgfutil@color command is used. It
+% should purge any internal settings of stroking and filling
+% color. After this call, till the next use of a command like
+% \pgfsys@color@rgb@fill, the current color installed by the \pgfutil@color
+% command should be used.
+
+\def\pgfsys@color@unstacked#1{}
+% This slightly obscure command causes the color stack to be
+% tricked. When called, this command should set the current color to
+% #1 without causing any change in the color stack.
+
+
+
+%
+%
+% Coordinate system transformations
+%
+%
+
+\def\pgfsys@transformcm#1#2#3#4#5#6{\pgf@sys@fail{transformations}}

+\def\pgfsys@beginscope{\pgf@sys@fail{scoping}}
+% Saves the current graphic state on a graphic state stack. All
+% changes to the graphic state parameters mentioned for \pgfsys@stroke
+% and \pgfsys@fill will be local to the current graphic state and will
+% the old values will be restored after endscope is used.
+%
+% WARNING: pdf and postscript differ with respect to the question of

+% Transparency
+%
+%
+
+\def\pgfsys@stroke@opacity#1{\pgf@sys@fail{opacity}}
+% Sets the opacity of stroking operations. 1 means fully opaque, 0
+% means fully transparent.
+
+\def\pgfsys@fill@opacity#1{\pgf@sys@fail{opacity}}
+% Sets the opacity of filling operations. 1 means fully opaque, 0
+% means fully transparent.
+
+\def\pgfsys@transparencygroupfrombox#1{\pgf@sys@fail{transparency groups}}
+% This takes a TeX box and converts it into a transparency
+% group. This means that any transparency settings apply to the box as
+% a whole. For instance, if a box contains two overlapping black
+% circles and you draw them normally with 50% transparency, then the
+% overlap will be darker than the rest. By comparison, if the circles
+% are part of a transparency group, the overlap will get the same
+% color as the rest.
+
+\def\pgfsys@definemask{\pgf@sys@fail{image masks}}
+% This command declares a mask for usage with images. It works similar
+% to \pgfsys@defineimage: Certain macros are set when the command is
+% called. The result should be to set the macro \pgf@mask to a pdf
+% object count that can subsequently be used as a soft mask. The
+% following macros will be set when this command is invoked:
+%
+% - \pgf@filename
+% File name of the mask to be defined.
+%
+% - \pgf@maskmatte
+% The so-called matte of the mask (see the pdf documentation for
+% details). The matte is a color specification consisting of 1, 3 or
+% 4 numbers between 0 and 1. The number of numbers depends on the
+% number of color channels in the image (not in the mask!). It will
+% be assumed that the image has been preblended with this color.
+
+\def\pgfsys@fadingfrombox#1#2{\pgf@sys@fail{fadings}}

+\def\pgfsys@usefading#1#2#3#4#5#6#7{\pgf@sys@fail{fadings}}

+% Shading commands
+%
+%
+
+\def\pgfsys@horishading#1#2#3{\pgf@sys@fail{shadings}\pgf@sys@noshading{#1}}
+% Declares a horizontal shading for later use. The effect of this
+% command should be the definition of a macro called `@pgfshading#1!'
+% (or \csname @pdfshading#1!\endcsname, to be precise). When invoked,
+% this new macro should insert a shading at the current position.
+%
+% #1 is the name of the shading, which is also used in the output
+% macro name. #2 is the height of the shading and must be given as a
+% TeX dimension like `2cm' or `10pt'. #3 is a shading color
+% specification as specified in the pgfuserguide. The shading
+% specification implicitly fixes the width of the shading.
+%
+% When `@pgfshading#1!' is invoked, it should insert a box of height
+% #2 and the width implicit in the shading declaration.
+
+\def\pgfsys@vertshading#1#2#3{\pgf@sys@fail{shadings}\pgf@sys@noshading{#1}}
+% Like horishading, only for vertical shadings. This time, the height
+% of the shading is implicit in #3 and the width is given as #2.
+
+\def\pgfsys@radialshading#1#2#3{\pgf@sys@fail{shadings}\pgf@sys@noshading{#1}}
+% Declares a radial shading. Like the previous macros, this command
+% should setup the macro `@pgfshading#1!', which upon invocation
+% should insert a radial shading whose size is implicit in #3.
+%
+% The parameter #2 is a pgf point specification if the starting point
+% of the shading. See the pgfuserguide for details.
+
+\def\pgfsys@functionalshading#1#2#3#4{\pgf@sys@fail{shadings (functional)}\pgf@sys@noshading{#1}}
+% Declares a shading using a PostScript-like function that provides a
+% color for each point. Like the previous macros, this command
+% should setup the macro `@pgfshading#1!' so that it will produce a
+% box containing the desired shading.
+%
+% Parameter #1 is the name of the shading. Parameter #4 is a
+% Postscript-like function (type 4 function of the PDF specification)
+% as described in Section 3.9.4 of the PDF Specification version 1.7.
+% Parameter #2 and #3 are pgf point specifications that specifies the
+% lower left and upper right coordinate.
+%
+% When function #4 is evaluated, the coordinate of the current
+% point will be on the (virtual) PostScript stack in bp units. After
+% the function has been evaluated, the stack should consist of three
+% numbers (not integers! - the Apple PDF renderer is broken in this
+% regard, so add cvr's at the end if needed) that represent the red,
+% green, and blue components of the color.
+%
+% A buggy #4 will result is *totally unpredictable chaos* during
+% rendering.

+% This command declares a new colored or uncolored pattern. Uncolored
+% patterns have no inherent color, the color is provided when they are
+% set. Colored patters have an inherent color.
+% #1 = name of the pattern (must be a plain suffix for use in
+% postscript/pdf/etc.)
+% #2 to #5 = four coordinates describing the corners of a bounding box
+% of pattern cells
+% #6 = x-step
+% #7 = y-step
+% #8 = pattern code
+% #9 = 0 if uncolored patter, 1 if colored pattern.
+
+\def\pgfsys@setpatternuncolored#1#2#3#4{\pgf@sys@fail{patterns}}
+% Sets an uncolored pattern #1 as filling color. The numbers #2, #3,

+%
+%
+
+% Marks the current position on the page. This position can later be

+\def\pgfsys@markposition#1{\pgf@sys@fail{marking the current position}}
+
+% Sets #2 to a pgfpoint macro that returns the position #1 is
+% returned in a coordinate system where the x-axis goes right and the
+% y-axis goes up. The origin of this coordinate system may or may not
+% lie in the lower left corner; you should shift the coordinate system
+% to the position "pgfpageorigin" to make sure that the origin is at
+% the lower left corner. Typically, getting this position
+% requires two runs of TeX. On the first run, the macro will be set to
+% \relax, indicating that the position is not available.
+%
+% If #1 is set to the special position "pgfpageorigin", the position
+% of the the lower left page corner is returned.

+
+\def\pgfsys@transformxyscale#1#2{\pgfsys@transformcm{#1}{0}{0}{#2}{0bp}{0bp}}
+% This command will scale the low-level coordinate system (and

+% y-direction. Note that this applies to everything, including
+% lines. So a scaled line will have a different width and may even

+%
+% In essence, this command does the same as if you first said

+% Called, when an image should be defined.
+%
+% This command does not take any parameters. Instead, certain macros
+% will be preinstalled with appropriate values when this command is
+% invoked. These are:
+%
+% - \pgf@filename
+% File name of the image to be defined.
+%
+% - \pgf@imagewidth
+% Will be set to the desired (scaled) width of the image.
+%
+% - \pgf@imageheight
+% Will be set to the desired (scaled) height of the image.
+%
+% If this macro and also the height macro are empty, the image
+% should have its `natural' size.
+%
+% If exactly only of them is specified, the undefined value the
+% image is scaled so that the aspect ratio is kept.
+%
+% If both are set, the image is scaled in both directions
+% independently, possibly changing the aspect ratio.
+%
+%
+% The following macros presumable mostly make sense for drivers that
+% can handle pdf:
+%
+% - \pgf@imagepage
+% The desired page number to be extracted from a multi-page
+% `image'.
+%
+% - \pgf@imagemask
+% If set, it will be set to `/SMask x 0 R', where x is the pdf
+% object number of a soft mask to be applied to the image.
+%
+% - \pgf@imageinterpolate
+% If set, it will be set to `/Interpolate true' or `/Interpolate
+% false', indicating whether the image should be interpolated in
+% pdf.
+%
+%
+% The command should now setup the macro \pgf@image such that calling
+% this macro will result in typesetting the image. Thus, \pgf@image is
+% the `return value' of the command.

+
+
+% This package provides the pgf system path abstraction layer. This
+% layer is used to construct paths first ``abstractly.'' These
+% abstract paths can still be modified, before they are ``made
+% concrete.''
+%
+% An abstract path consists of a sequence of basic building blocks,
+% each of which is a tuple consisting of two numbers (specifying a
+% coordinate) and a token. Possible tokens are:
+%
+% 1. moveto
+% 2. lineto
+% 3. rectcorner
+% 4. rectsize
+% 5. curvetosupporta
+% 6. curvetosupportb
+% 7. curveto
+% 8. closepath
+% 9. specialround
+%
+% A curveto must always be preceeded by a curvetosupporta and a
+% curvetosupportb. A non-empty path must always begin with a
+% moveto. The coordinates of a closepath are non-specified, currently,
+% but they might be set to the coordinate of the path segment start,
+% in the future.
+
+
+% Access to the current path:
+%
+% Lots of stuff is added to the current path and it can get very long
+% (containing literally tens of thousands of tokens). For such macros,
+% adding things using a simple "g@addtomacro" takes more and more
+% time, resulting in quadratic runtime. To avoid this, ideally, one
+% would collect things in an array and then use a divide and conquer
+% merger. A simple intermediate solution is the following, implemented
+% here: We have the path and two buffers. New tokens are added to the
+% first buffer, which is quite small. When it overflow, its contents
+% is added to the second buffer, which is large. If that buffer
+% overflow, the contents is finally added to the main path (which can
+% have arbitrary length). Whenever the main path is set or read, the
+% buffers are flushed.
+%
+% Because of this buffering, it is imperative that the main path is
+% accessed only vie appropriate interface macros.
