-Title: The Node file format
+# The Node file format
 
 GSK render nodes can be serialized and deserialized using APIs such as `gsk_render_node_serialize()` and `gsk_render_node_deserialize()`. The intended use for this is development - primarily the development of GTK - by allowing things such as creating testsuites and benchmarks, exchanging nodes in bug reports. GTK includes the `gtk4-node-editor` application for creating such test files.
 
 The format is a text format that follows the [CSS syntax rules](https://drafts.csswg.org/css-syntax-3/). In particular, this means that every array of bytes will produce a render node when parsed, as there is a defined error recovery method. For more details on error handling, please refer to the documentation of the parsing APIs.
 
 The grammar of a node text representation using [the CSS value definition syntax](https://drafts.csswg.org/css-values-3/#value-defs) looks like this:
-
-    document: <@-rule>*<node>
-    @-rule: @cicp "name" { <property>* }
-    node: container [ "name" ] { <document> } | <node-type> [ "name" ] { <property>* } | "name"
-    property: <property-name>: <node> | <value> ;
+**document**: `<node>\*`
+**node**: container [ "name" ] { <document> } | `<node-type> [ "name" ] { <property>* }` | "name"
+**property**: `<property-name>: <node> | <value> ;`
 
 Each node has its own `<node-type>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.

 Just like nodes, textures can be referenced by name. When defining a named texture, the name has to be placed in front of the URL.
 
-# Color states
-
-Color states are represented either by an ident (for builtin ones) or a string
-(for custom ones):
-
-    color-state: <ident> | <string>
-
-Custom color states can be defined at the beginning of the document, with an @‌cicp rule.
-
-The format for @‌cicp rules is
-
-    @‌cicp "name" {
-      ...
-    }
-
-The following properties can be set for custom color states:
-
-| property  | syntax           | default  | printed     |
-| --------- | ---------------- | -------- | ----------- |
-| primaries | `<integer>`      | 2        | always      |
-| transfer  | `<integer>`      | 2        | always      |
-| matrix    | `<integer>`      | 2        | always      |
-| range     | `<range>`        | full     | non-default |
-
-Note that the primaries, transfer and matrix properties always need
-to be specified, since GTK does not allow creating color state objects
-with these being set to 2 (== unspecified).
-
-Range can have the following values:
-
-    range: narrow | full
-
-# Colors
-
-Colors can be specified with a variation of the modern CSS color syntax:
-
-    color(<color-state> <number> <number> <number> ["/" <number>])
-
-The traditional syntax for sRGB colors still works as well:
-
-    rgba(<number>, <number>, <number>, <number)
-    rgb(<number, <number>, <number>)
-
-# Rectangles
-
-Rectangles can be specified just as four integers for x, y, width and height:
-
-    rect: <number> <number> <number> <number>
-
-Rounded rectangles use a CSS-like syntax:
-
-    rounded-rect: <rect> [ "/" <number>{1,4} [ "/" <number>{1,4} ] ]

+GTK extends the CSS syntax with several additional ways to specify colors.
 
 The first is a reference to a color defined via a @define-color rule in CSS.
 The syntax for @define-color rules is as follows:
 
 ```
-@define-color name color
+@define-color Name Color
 ```
 
 To refer to the color defined by a @define-color rule, prefix the name with @.
 
-The standard CSS mechanisms that should be used instead of @define-color are
-custom properties, :root and var().
-
 GTK also supports color expressions, which allow colors to be transformed to
 new ones. Color expressions can be nested, providing a rich language to
 define colors. Color expressions resemble functions, taking 1 or more colors
 and in some cases a number as arguments.

-DESCRIPTION
------------
-
-``gtk4-image-tool`` can perform various operations on images.
-
-COMMANDS
---------
-
-Information
-^^^^^^^^^^^
-
-The ``info`` command shows general information about the image, such
-as its format and color state.
-
-Showing
-^^^^^^^
-
-The ``show`` command displays one or more images, side-by-side.
-
-``--undecorated``
-
-Removes window decorations. This is meant for rendering of exactly the image
-without any titlebar.
-
-Compare
-^^^^^^^
-
-The ``compare`` command compares two images. If any differences are found,
-the exit code is 1. If the images are identical, it is 0.
-
-``--output=FILE``
-
-  Save the differences as a png image in ``FILE``.
-
-``--quiet``
-
-  Don't write results to stdout.
-
-Conversion
-^^^^^^^^^^
-
-The ``convert`` command converts the image to a different format or color state.
-
-``--format=FORMAT``
-
-  Convert to the given format. The supported formats can be listed
-  with ``--format=list``.
-
-``--color-state=COLORSTATE``
-
-  Convert to the given color state. The supported color states can be
-  listed with ``--format=list``.
-
-``--cicp=CICP``
-
-  Convert to a color state that is specified as a cicp tuple. The cicp tuple
-  must be specified as four numbers, separated by /, e.g. 1/13/6/0.
-
-Relabeling
-^^^^^^^^^^
-
-The ``relabel`` command changes the color state of an image without conversion.
-This can be useful to produce wrong color renderings for diagnostics.
-
-``--color-state=COLORSTATE``
-
-  Relabel to the given color state. The supported color states can be
-  listed with ``--format=list``.
-
-``--cicp=CICP``
-
-  Relabel to a color state that is specified as a cicp tuple. The cicp tuple
-  must be specified as four numbers, separated by /, e.g. 1/13/6/0.

- * GdkCicpParams:
- *
- * The `GdkCicpParams` struct contains the parameters that define
- * a colorstate according to the ITU-T H.273
- * [specification](https://www.itu.int/rec/T-REC-H.273/en).
- *
- * See the documentation of individual properties for supported values.
- *
- * The 'unspecified' value (2) is not treated in any special way, and
- * must be replaced by a different value before creating a color state.
- *
- * `GdkCicpParams` can be used as a builder object to construct a color
- * state from Cicp data with [method@Gdk.CicpParams.build_color_state].
- * The function will return an error if the given parameters are not
- * supported.
- *
- * You can obtain a `GdkCicpParams` object from a color state with
- * [method@Gdk.ColorState.create_cicp_params]. This can be used to
- * create a variant of a color state, by changing just one of the cicp
- * parameters, or just to obtain information about the color state.

- * GdkMemoryTextureBuilder:
- *
- * `GdkMemoryTextureBuilder` is a builder used to construct [class@Gdk.Texture] objects
- * from system memory provided via [struct@GLib.Bytes].
- *
- * The operation is quite simple: Create a texture builder, set all the necessary
- * properties - keep in mind that the properties [property@Gdk.MemoryTextureBuilder:bytes],
- * [property@Gdk.MemoryTextureBuilder:stride], [property@Gdk.MemoryTextureBuilder:width],
- * and [property@Gdk.MemoryTextureBuilder:height] are mandatory - and then call
- * [method@Gdk.MemoryTextureBuilder.build] to create the new texture.
- *
- * `GdkMemoryTextureBuilder` can be used for quick one-shot construction of
- * textures as well as kept around and reused to construct multiple textures.
- *
- * Since: 4.16
