- output routine for headers and footers) to `\_ensureblackA` which sets
- Black at the start of its parameter and returns to the current color at the
- end of its parameter.
-
- The current color is saved into `\_currentcolor` macro and colorstack is pushed.
- Finally, the `\_colorstackpop` is initialized by `\aftergroup` if
- `\localcolor` is declared.
-
- You can save the current color to your macro by `\let\yourmacro=\_currentcolor`
- and you can return to this color by the command `\_setcolor\yourmacro`.

+ \`\_setcolor``{<color-data>}{<fill-op>}{<stroke-op>}` is defined here.

+ before and prepare mapping from this integer value to the <color data>
+ and increments \^`\_colorcnt`.
+ If the <color data> were used already, then \^`\_setcolor`
+ does `\_colorattr=<stored-value>`.

-The colors have different behavior than fonts. Marks (whatsits) with color

-By default, \OpTeX/ sets `\localcolor`. It means that the typesetting

-write `\Black` explicitly. This is implemented using the `\aftergroup` feature.
-There is a limitation of this feature: when a color selector is used in a

-reconstruction of the previous color is processed at `\setbox` time, no in the
-box itself. You must correct it by double group:

-The implementation of colors is based on colorstack, so the current color
-can follow across more pages. It is not so obvious because PDF viewer (or PDF
-interpreter) manipulates with colors locally at each PDF page and it
-initializes each PDF page with black on white color.
+\secc Basic concept
+
+Setting of color in PDF is handled by graphics operators which change the
+graphics context. Colors for fills/strokes are distinguished, but apart from
+that, only one color is active at time and is used for all material drawn by
+following graphics operators, until next color is set. Each PDF content (e.g.
+page or form XObject) has its own graphics context, that is initialized from
+zero. Hence we have different concept of selecting fonts in \TeX/ (it
+depends on \TeX/ groups but does not depends on pages) and color handling in
+PDF.
+
+\TeX/ itself has no concept of colors. Colors have always been handled by
+inserting whatsits (either using `\special` for DVI or using
+`\pdfliteral`/`\pdfcolorstack` for PDF). It is very efficient and \TeX/ doesn't
+even have to know anything about colors, but it is also problematic in many
+ways.
+
+That is the reason why we decided to change color handling from
+`\pdfcolorstack` to \LuaTeX/ attributes in version 1.04 of \OpTeX. Using
+attributes, the color setting behaves exactly like font selection from \TeX/
+point of view: it respects \TeX/ groups, colors can span more pages,
+independent colors can be set for `\insert`s, etc. Moreover, once a material is
+created (using `\setbox` for example) then it has its fonts and its colors
+frozen and you can rely on it when you are using e.g. `\unhbox`. There are no
+internal whatsits for colors which can interfere with other typesetting
+material. In the end something like setting text to red (`{\Red text}`) should
+have the same nice behavior like setting text to bold (`{\bf text}`).
+
+\LuaTeX/ attributes can be set like count register -- one attribute holds one
+number at a time. But the value of attribute is propagated to each created
+typesetting element until the attribute is unset or set to another value. Very
+much like the font property. We use one attribute \^`\_colorattr` for storing
+the currently selected color (in number form).
Macros \^`\setcmykcolor``{<C> <M> <Y> <K>}` or \^`\setrgbcolor``{<R> <G> <B>}`
-or\nl \^`\setgreycolor``{<Grey>}` should be used in color selectors or user can
-specify these macros explicitly.
+or\nl \^`\setgreycolor``{<Grey>}` are used in color selectors. These
+macros expand to internal \^`\_setcolor` macro which sets the \^`\_colorattr`
+attribute to an integer value and prepares mapping between this value and the real
+color data. This mapping is used just before each `\shipout` in output routine.
+The \^`\_preshipout` pseudo-primitive is used here, it converts attribute
+values to internal PDF commands for selecting colors.

+ This package is \OpTeX/'s compatibility layer for PGF/TikZ. When users do
+ `\load[tikz]` they expect `tikz.tex` to be loaded, but this file gets loaded
+ instead. It does load `tikz.tex`, but also does fixups.

+ PGF's `\pgfutil@everybye` hooks into `\end`, but normally \OpTeX/ uses the
+ prefixed `\_end`. Here we make it hook into `\_byehook` which should
+ hopefully be preserved by all \OpTeX/ macro writers.

+ There is a general disagreement about the use/meaning of `\hoffset` and
+ `\voffset` -- \LaTeX/, the \LaTeX/ `crop`
+ package\fnote{\url{https://www.ctan.org/pkg/crop}}, TikZ, and \OpTeX/ all
+ try to use the values differently. Unfortunately this means a broken
+ behaviour observed by end users in
+ \OpTeX/\fnote{\url{https://github.com/pgf-tikz/pgf/issues/983}}.
+
+ The problem at hand is that PGF nowadays sets the page origin to include
+ `\hoffset` and `\voffset`. We instead set it to the origin (i.e. the point
+ $(0, 0)$).
