label: Cache extents

When a label has width-chars or max-width-chars set, we end

its work. We can avoid this by caching a few sizes.

 freestanding chapters. As an exception, man pages for tools are currently
 maintained in docbook, since the conversion from markdown to docbook is
 losing too much of the expected formatting.
 
 In addition to typical markdown formatting such as \*emphasis\* or \_italics\_,
-the GTK documentation supports additional link formats, like:
+gtk-doc supports a few abbreviations for cross-references and formatting:
 
-`[class@Namespace.ClassName]`
+`#ClassName`

-`[method@Namespace.Method.name]`

-### Introspection annotations

+/**
+ * SECTION:gtkshortcut
+ * @Title: GtkShortcut
+ * @Short_desc: A key shortcut
+ *

+```
 
-The purpose of the annotations for function arguments, properties, signals,
-etc., is to describe the API in a machine readable way. The annotations
-are consumed by language bindings and by the documentation tools.

-For more information about the annotations used by GTK, you should refer to
-the [GObject Introspection documentation][gi-annotations].

-[gi-annotations]: https://gi.readthedocs.io/en/latest/annotations/giannotations.html
-
-### Type description
-
-Each type should be annotated with a description of what the type does.
-
-For classes, the description should contain an overview of the type;
-what it does; typical use cases; and idiomatic examples of its use.
-
-For widget classes, the description should also contain:
-
-  - special XML elements and attributes parsed by the class, in case of a
-    custom GtkBuildable implementation
-  - the CSS element name to be used by selectors
-  - the CSS selector hierarchy for children, in case of a composite widget
-  - the accessible role of the class
-
-Each section in a type description can have a heading; it's preferred to use
-second and third level headings only.
+   For classes, the title should be the name of the class. While it's
+   possible to add section titles directly to the `sections.txt` file, this
+   is considered deprecated, and should not be done for newly written code.

-## Functions to support using cairo
-
-[Cairo](http://cairographics.org) is a graphics library that supports vector
-graphics and image compositing that can be used with GTK.
-
-GDK does not wrap the Cairo API; instead it allows to create Cairo
-drawing contexts which can be used to draw on [class@Gdk.Surface]s.
-
-Additional functions allow use [struct@Gdk.Rectangle]s with Cairo
-and to use [struct@Gdk.RGBA], `GdkPixbuf`, and [class@Gdk.Surface]
-instances as sources for drawing operations.
-
-For more information on Cairo, please see the
-[Cairo API reference](https://www.cairographics.org/manual/).

-The GDK and GTK headers annotate deprecated APIs in a way that produces
-compiler warnings if these deprecated APIs are used. The warnings
-can be turned off by defining the macro `GDK_DISABLE_DEPRECATION_WARNINGS`
-before including the `gdk.h` header.
-
-GDK and GTK also provide support for building applications against defined
-subsets of deprecated or new APIs. You can define the macro
-`GDK_VERSION_MIN_REQUIRED` to specify up to what version you want to receive
-warnings about deprecated APIs; and the macro `GDK_VERSION_MAX_ALLOWED` to
-specify the newest version whose API you want to use. If you attempt to use
-a function deprecated before the version of GTK specified in
-`GDK_VERSION_MIN_REQUIRED`, or a function introduced after the version of
-GTK specified in `GDK_VERSION_MAX_ALLOWED`, the compiler will warn you when
-building your code.
